Understanding Voice Assistant Ecosystem Compatibility in 2026
The Big Three: Alexa, Google Assistant, and Siri Evolution
Amazon’s Alexa has matured into Alexa+ with on-device natural language processing, meaning your lock can now process complex commands without cloud dependency. Google’s Assistant has merged deeper with Gemini, enabling contextual conversations where “lock up for the night” triggers your entire security routine. Apple’s Siri finally supports third-party smart locks natively in HomeKit Secure Video, eliminating the need for clunky bridge devices. When evaluating locks, verify certification levels—look for “Works with Alexa+ Certified” badges that guarantee local voice processing, Google Home’s “Seamless Setup” designation for automatic hub detection, and Apple’s “HomeKit Secure” label ensuring end-to-end encryption.
Emerging Voice Platforms to Watch
Samsung’s Bixby has pivoted to Bixby Home Grid, creating a decentralized voice network between Samsung appliances that could control your lock even during internet outages. Meanwhile, open-source voice assistants like Mycroft and Rhasspy are gaining traction among privacy-conscious users, with some lock manufacturers offering local-only voice packs. If you’re building a brand-agnostic smart home, prioritize locks supporting multiple simultaneous voice platforms through Matter’s multi-admin feature, which allows a single lock to respond to Alexa, Google, and Siri without conflicts.
Matter Protocol: The Game Changer for 2026
Matter 1.3 has finally delivered on its promise for smart locks, enabling true cross-platform voice control and eliminating the “walled garden” problem. A Matter-certified lock pairs directly with any Matter-compatible voice hub, whether that’s an Echo Show, Google Nest Hub, or Apple TV. Crucially, Matter over Thread provides mesh networking reliability that Wi-Fi can’t match—your lock stays reachable even if your router reboots. When shopping, insist on Matter-certified devices with Thread border router support, not just Matter-over-Wi-Fi, which still depends on cloud connectivity.
Key Security Standards You Can’t Compromise On
Encryption Protocols: Beyond AES-256
While AES-256 remains the baseline, 2026’s locks implement quantum-resistant algorithms like CRYSTALS-Kyber for key exchange during voice authentication sessions. Look for locks advertising “PQC-ready” (Post-Quantum Cryptography) certification, ensuring your device won’t become obsolete when quantum computing breaks current standards. Additionally, verify that voice commands use ephemeral session keys—each “unlock the door” command generates a unique encryption key that expires immediately after execution, preventing replay attacks.
Biometric Authentication Advances
Voice biometrics in 2026 go far beyond simple wake word recognition. Advanced locks create 3D voiceprints analyzing over 200 vocal characteristics, making spoofing nearly impossible. Some models now require “liveness detection”—subtle vocal stress patterns that prove you’re a live human, not a recording. When evaluating biometric features, check for on-device voice template storage using secure enclaves, not cloud-based voice profiles. The gold standard is FIDO2 certification for voice authentication, which ensures your voice data never leaves the lock’s hardware security module.
Physical Security vs. Digital Security Balance
A lock with military-grade encryption is useless if a crowbar defeats it in seconds. Verify ANSI/BHMA Grade 1 certification—the highest residential rating—with specific testing for smart lock components. The best 2026 models undergo “digital torque testing” that simulates app-based forced entry attempts, and “voice jamming resistance” testing against RF interference. Look for locks with separate mechanical and electronic locking cylinders, so a digital failure doesn’t compromise physical security.
Installation Complexity: What Your Door Needs
Assessing Your Current Door Hardware
Before falling in love with any lock, measure your door’s backset (2-3/8" or 2-3/4"), thickness (1-3/8" to 2-1/4" standard), and cross-bore diameter (2-1/8"). 2026’s smart locks increasingly require “smart door prep”—a reinforced strike plate with integrated sensors and a dedicated 1" hole for antenna placement. If you have a multipoint locking system common in European doors, you’ll need locks specifically certified for MPL compatibility, which use a motorized gearbox rather than a simple deadbolt throw.
Professional vs. DIY Installation Realities
While manufacturers claim “15-minute installation,” voice-integrated locks demand precise alignment for reliable operation. A 1/8" misalignment can cause the motor to strain, draining batteries 40% faster and causing voice command failures. DIY is viable if you own a door alignment tool and digital caliper, but professional installation ($150-$250) often includes firmware optimization, voice training for all household members, and integration with existing smart home scenes. Many brands now offer “certified installer networks” that guarantee voice recognition accuracy post-installation.
Retrofit vs. Deadbolt Replacement Options
Retrofit adapters that fit over existing deadbolts preserve your original keys but sacrifice voice responsiveness—they rely on detecting manual turns rather than motorized control. Full deadbolt replacements offer true voice-activated locking/unlocking but require permanent modification. In 2026, “hybrid retrofit” models have emerged, adding a motorized cam to your existing deadbolt while preserving key access. These cost 30% more but eliminate the risk of electronic lockout during power failures.
Power Management and Battery Life Innovations
Battery Types and Longevity Expectations
Lithium-thionyl chloride batteries now dominate premium locks, delivering 18-24 months of life versus 6-12 months from alkaline cells. However, voice assistant integration’s always-listening mode consumes 15-20% more power. Calculate real-world battery life by checking the lock’s “voice standby rating”—measured in milliwatts during passive listening. Locks with “adaptive listening” reduce power draw by 60% when you’re away, using geofencing to wake the microphone only as you approach.
Solar and Kinetic Energy Harvesting Features
2026’s flagship locks integrate photovoltaic cells into the keypad housing, trickle-charging an internal supercapacitor. In sunny climates, this extends battery life indefinitely. Kinetic harvesting captures energy from door vibrations and manual lock operations, generating enough power for 2-3 voice commands daily without battery drain. While these features add $50-$75 to the price, they pay for themselves in battery savings within two years. Verify the harvesting efficiency rating—look for locks that generate at least 50mW per hour in average conditions.
Backup Power Solutions for 2026 Models
Voice-enabled locks without power are just expensive deadbolts. The best models offer three-tier backup: a 9V battery terminal under the keypad for emergency power, a USB-C port for portable battery packs, and a “mechanical override” mode where a specific voice command sequence (known only to you) releases a spring-loaded mechanical key. Some locks now include supercapacitors that store enough charge for 50+ voice commands during outages. Test the backup system before final installation—many failures occur because homeowners don’t know the override sequence.
Connectivity Protocols: Making the Right Choice
Wi-Fi 6E and Thread Networks Explained
Wi-Fi 6E’s 6GHz band eliminates interference from legacy devices, providing sub-100ms voice command response times. However, it consumes 3x more power than Thread. Thread mesh networks create a self-healing fabric where each lock acts as a repeater, extending coverage to gates and garages. The sweet spot for 2026 is “Wi-Fi 6E with Thread fallback”—locks that primarily use Thread for voice commands but seamlessly switch to Wi-Fi for firmware updates and remote access. This hybrid approach reduces latency while preserving battery life.
Bluetooth 5.3 and Ultra-Wideband Integration
Bluetooth 5.3’s Periodic Advertising Enhancement allows your lock to broadcast its status without constant connection, enabling voice assistants to report “front door is locked” instantly. Ultra-Wideband (UWB) integration enables spatial awareness—your lock knows you’re standing at the door versus walking by on the sidewalk. This prevents accidental voice unlocks from neighbors. When evaluating UWB locks, check for “angle of arrival” (AoA) precision—sub-10cm accuracy ensures the lock only responds when you’re within 3 feet of the door.
Hub Requirements and Hub-Less Architectures
Matter’s multi-hub topology means your lock can connect to any combination of Echo, Nest, and Apple TV devices simultaneously. Hub-less locks with built-in Wi-Fi offer simpler setup but lack mesh reliability. For large homes, prioritize locks with “distributed hub intelligence”—they automatically connect to the nearest hub with the strongest signal, switching dynamically as you move through your home. Verify your chosen lock supports at least three concurrent hub connections to avoid single points of failure.
Voice Command Capabilities and Natural Language Processing
Basic vs. Advanced Voice Commands
Basic integration offers “Alexa, lock the front door.” Advanced locks understand contextual commands like “I’m going for a run, keep the door unlocked for 30 minutes” or “Let the dog walker in every Tuesday and Thursday at 2 PM.” The key differentiator is “intent parsing”—the lock’s ability to extract complex parameters from natural speech. Test this by asking demo units compound commands. Also check for “negative command recognition”—the lock should reject ambiguous commands like “unlock… wait, no, lock the door” without executing the partial command.
Multi-User Voice Recognition Features
Households require granular voice permissions. 2026’s locks support up to 50 voice profiles, each with customizable access levels. Your teenager’s voice might only unlock the door during curfew hours, while a housekeeper’s voice works only on scheduled days. The critical feature is “voice anti-spoofing” that detects synthesized speech—some locks now emit inaudible ultrasonic pulses and listen for the unique reflection pattern of a human vocal tract, making deepfake voice attacks virtually impossible.
Context-Aware Commands and Routines
The magic happens when your lock understands situational context. Saying “goodnight” should lock the door, arm the security system, and dim the lights—but only if all residents are home. Advanced locks cross-reference voice commands with smartphone presence, indoor motion sensors, and even smart bed presence detectors. Look for “routine branching” capabilities in the lock’s app, allowing you to create if-then scenarios: “If I say ‘I’m leaving’ and no other phones are home, then lock and arm; if others are present, just lock.”
Mobile App Integration and Remote Access Features
App Ecosystem Quality Indicators
A lock’s app is your backup control plane. In 2026, quality indicators include offline mode functionality (controlling the lock via Bluetooth when internet fails), “voice command simulation” for testing routines without speaking, and “digital twin” visualization showing real-time lock mechanics. Check app store reviews specifically for “voice sync reliability”—poor ratings here indicate frequent desynchronization between the lock’s voice module and cloud services. The app should also provide “voice health diagnostics,” reporting microphone sensitivity and background noise levels that could affect recognition.
Guest Access Management Evolution
Temporary voice access for guests is the new frontier. Instead of sharing codes, you can now enroll a guest’s voice for a specific duration. The lock generates a temporary voice template that auto-expires, leaving no permanent biometric data. For Airbnb hosts, look for “voice access portals”—guests receive a link to record their voice, which gets encrypted and sent directly to your lock without passing through the manufacturer’s servers. Verify this uses zero-knowledge architecture, meaning even the vendor can’t access guest voice data.
Activity Logs and Smart Notifications
Voice command logs should be forensic-level detailed: timestamped audio waveforms (stored locally), recognized intent, and execution result. The best locks use AI to filter noise from notifications—instead of alerting “voice command failed” 20 times when your TV mentions “unlock,” they recognize the audio source and suppress false alarms. Look for “notification intelligence” settings that learn which alerts you actually check, reducing noise by 90% over time.
Geofencing and Proximity-Based Automation
GPS vs. Bluetooth Beacon Accuracy
GPS geofencing suffers from 100-meter accuracy, causing premature unlocking while you’re still a block away. Bluetooth 5.3 beacons with AoA positioning achieve 1-meter precision but drain phone batteries. The 2026 solution is “hybrid proximity”—locks use GPS for coarse location (arming when you leave the neighborhood) and UWB beacons for fine-grained unlock as you approach the door. Check for “beacon power optimization” in the lock’s settings, which reduces phone battery impact to less than 2% per day.
Privacy Concerns with Location Tracking
Constant location monitoring raises surveillance concerns. Premium locks now implement “on-device geofencing”—your phone sends encrypted “entering/exiting” tokens rather than raw GPS coordinates. The lock never knows your exact location, only that you’ve crossed a predefined boundary. Look for locks certified by the EFF’s “Privacy by Design” standard, which mandates that location data is hashed with a daily rotating key, making historical tracking impossible even if the vendor’s servers are compromised.
Setting Up Reliable Auto-Unlock/Lock
Auto-unlock fails when your phone’s OS kills background apps. 2026’s locks combat this with “persistent presence channels”—a low-power connection that survives app termination. For reliability, set up “multi-factor presence”: auto-unlock only triggers when your phone’s Bluetooth beacon, Wi-Fi MAC address, and voice assistant presence all align. Test the setup by walking your actual approach path multiple times at different speeds. The lock should unlock consistently within 3-5 seconds of reaching your doorstep, never earlier.
Design Aesthetics and Build Quality Considerations
Material Durability for Extreme Weather
Voice-enabled locks contain sensitive microphones that fail in extreme temperatures. For cold climates, verify “cryogenic certification”—tested to -40°F with voice recognition accuracy above 95%. In coastal areas, insist on 316 marine-grade stainless steel housings; lesser alloys corrode within 18 months, blocking microphone ports. The keypad overlay should be “piezoelectric glass”—it works when wet and won’t crack from thermal shock. Check the IP rating: IP65 is minimum, but IP68 with “submersion voice testing” ensures the lock survives flooding.
Finish Options and Fingerprint Resistance
Satin nickel and oil-rubbed bronze remain popular, but 2026’s finishes incorporate antimicrobial copper alloys that kill 99.9% of bacteria within hours—crucial for touchscreens. For voice-only operation, consider “microphone-optimized” finishes: matte black reduces audio reflection interference, while brushed textures minimize wind noise pickup. “Physical vapor deposition” (PVD) finishes offer 10-year corrosion warranties but can interfere with NFC communication if applied too thickly. Test voice recognition before finalizing finish selection.
ANSI Grade Ratings Explained
ANSI Grade 1 certification requires surviving 250,000 cycles and 10 door strikes with a sledgehammer. For voice locks, also demand “Grade 1V” (Voice) certification—a new 2026 standard testing microphone durability during impact tests and voice recognition accuracy after vibration stress. Some manufacturers cheat by placing mics away from the impact zone; true Grade 1V locks maintain voice function even with cracked housings. Verify the rating includes “motor endurance testing”—the deadbolt motor must operate flawlessly for 50,000 voice commands, not just manual turns.
Smart Home Ecosystem Integration Depth
Beyond Voice: Scene and Routine Creation
Your lock should serve as a scene trigger and actuator. When you say “movie night,” the lock should confirm it’s engaged, dim lights, and set the thermostat. Look for “scene complexity support” in specifications—can the lock handle nested conditions? For example: “If door is locked after 10 PM and motion is detected outside, then turn on floodlights and send alert.” The lock’s app should expose its full state machine (locked, unlocked, jammed, voice-pending) as triggerable conditions in Alexa Routines, Google Home Scripts, and Siri Shortcuts.
Interoperability with Cameras and Doorbells
Voice commands should coordinate with visual verification. Saying “unlock the door” while your video doorbell sees an unrecognized person should trigger a confirmation prompt: “I see someone unfamiliar. Are you sure?” This requires “synced device state” protocols where the lock subscribes to your doorbell’s person detection feed. Check for “video-verified unlock” features that automatically show the doorbell feed on your smart display when a voice unlock is attempted, allowing visual confirmation before execution.
Security System Integration Protocols
Standalone smart locks create security gaps. In 2026, leading locks integrate directly with alarm panels using DMP or Contact ID protocols—locking the door arms the system, while alarm triggers automatically deadbolt all exits. For voice control, ensure your lock supports “partitioned arming” common in commercial systems, allowing you to say “arm the perimeter” to lock specific doors while keeping interior doors accessible. Verify two-way status sync: if the alarm is tripped, the lock should ignore voice unlock commands until disarmed, preventing burglars from ordering the door open.
Privacy and Data Protection in 2026
Local vs. Cloud Processing Models
The privacy gold standard is “voice-on-edge”—your lock processes voice commands using its own neural processing unit, sending only anonymized intent tokens to the cloud. Cloud-dependent locks transmit audio snippets, creating subpoena risk. Check the lock’s “voice data residency” settings; premium models let you choose between three modes: full edge processing (fastest, most private), hybrid (complex commands use cloud NLP), and cloud-only (avoid entirely). Insist on locks with “audio data purging”—raw voice recordings are overwritten within 30 seconds if no wake word is detected.
Data Retention Policies to Demand
Voice command logs are legally discoverable. Reputable manufacturers offer “zero-retention” modes where successful commands are logged only as timestamps, with no audio stored. Failed commands (potential break-in attempts) retain 3-second audio clips for 7 days, then auto-delete. Read the privacy policy for “law enforcement disclosure statistics”—some vendors publish transparency reports showing how often they provide voice data to authorities. The best policies include “user-controlled encryption keys,” where you hold the key to decrypt any stored audio, making vendor compliance with subpoenas impossible.
GDPR and Emerging Privacy Regulations
Beyond GDPR, 2026 sees enforcement of the American Data Privacy Protection Act (ADPPA) and China’s PIPL. Locks sold globally must support “privacy mode” that disables all cloud voice features for users in regulated regions. Check for “regional firmware” options—switches that physically disable microphones and enable sign-only mode when privacy laws require. Some locks now include “legal jurisdiction indicators” in their app, showing which country’s laws apply to your voice data based on your account registration location.
Price vs. Value: Real-World Cost Analysis
Understanding Total Cost of Ownership
A $200 lock can cost $600 over three years. Factor in: battery replacements ($25/year), subscription fees for advanced voice features ($3-10/month), and professional installation ($150). Energy-harvesting models command a $100 premium but save $75 in batteries over their lifetime. Calculate “voice cost per command”—divide the total TCO by estimated commands (10 per day = 3,650/year). Premium locks often cost less per command due to longevity. Also consider “failure cost”—a cheap lock that mishears commands and requires a locksmith costs more than a reliable premium model.
Subscription Services: Necessary or Upsell?
Voice assistant integration itself never requires a subscription—that’s a red flag. However, “voice intelligence services” like learning your command patterns, multi-home voice sync, and advanced guest voice management often cost $5/month. Evaluate necessity by testing the lock without subscriptions for 30 days. If voice recognition accuracy drops below 95% or remote voice commands fail, the subscription is effectively mandatory. Some manufacturers offer “lifetime voice service” for a one-time $150 fee—worthwhile if you plan to own the lock over 5+ years.
Warranty and Support Quality Metrics
Standard warranties cover mechanical defects for 1-3 years, but voice components often have separate, shorter coverage. Demand “voice module warranty” of at least 2 years covering microphone failure and recognition degradation. Support quality is measured by “voice issue resolution time”—top brands guarantee callback within 4 hours for voice recognition problems and offer remote diagnostics where they can test your lock’s microphones and NLP engine without a technician visit. Check support forums for “voice drift” complaints—if users report recognition degrading after 6 months, the manufacturer likely uses cheap microphones that age poorly.
Future-Proofing Your Investment
Over-the-Air Update Commitments
Voice assistants evolve monthly; your lock must keep pace. Insist on manufacturers with “voice feature parity guarantees”—written commitments that new Alexa, Google, and Siri capabilities will be added via OTA within 90 days of platform release. Check the update history in the app store—frequent updates indicate active development. The lock should support “A/B firmware updates,” where new voice models are tested on a small user subset before wide release, preventing widespread recognition failures. Some brands now offer “beta voice channels” letting you opt into cutting-edge NLP features early.
Modular Hardware Design Trends
Voice recognition hardware improves rapidly. Modular locks allow you to swap the voice module (microphone array and NPU) without replacing the entire deadbolt. Look for “voice module upgradeability” in specs—locks with USB-C accessible modules that can be replaced in 5 minutes. This extends useful life from 3-5 years to 7-10 years. The best designs use “standardized voice cartridges” compatible across product lines, so a 2026 lock can accept a 2028 voice module with improved far-field recognition and accent support.
AI and Machine Learning Integration Roadmap
Ask manufacturers for their “voice AI roadmap.” Leading brands publish 2-year plans detailing upcoming features like emotion detection (unlocking differently if you sound stressed), accent adaptation (learning your family’s specific speech patterns), and predictive locking (locking automatically when your voice pattern indicates you’re leaving). Avoid locks using static voice models that never improve. The best continuously learn from your corrections—when you repeat a command, they adjust sensitivity without cloud dependency.
Common Pitfalls and How to Avoid Them
Voice Assistant Drift and Calibration Issues
Microphones drift over time, causing 10-15% accuracy loss annually. Combat this with quarterly “voice recalibration”—a 5-minute process where you read a standard phrase set. Some locks auto-calibrate by comparing current voiceprints to enrollment samples, but this risks false positives. Set a calendar reminder for manual calibration every season change; temperature fluctuations affect microphone sensitivity. If your lock lacks manual recalibration, it’s a disposable product.
Network Congestion and Performance Degradation
During peak hours, your Wi-Fi may delay voice commands by 3-5 seconds. Thread networks avoid this but can become congested with too many devices. Use a “network priority” setting in your router to reserve bandwidth for your lock’s MAC address. For Thread, limit each network to 32 devices—split your home into separate Thread networks per floor if needed. Test voice latency at 8 AM and 8 PM; if response time exceeds 2 seconds, your network is the bottleneck, not the lock.
Return Policies and Compatibility Guarantees
Voice integration is subjective—your accent may not work with certain NLP models. Insist on 60-day return policies specifically covering “voice incompatibility.” Some retailers offer “voice trial periods” where you can test the lock’s recognition accuracy before permanent installation. Get written confirmation that returns are accepted if voice accuracy falls below advertised rates (typically 95%). Keep the original packaging and avoid drilling additional holes until you’re certain the voice features meet your expectations.
Frequently Asked Questions
1. Will my smart lock still work if the internet goes down?
Yes, but functionality depends on the architecture. Locks with local voice processing and Thread connectivity maintain full voice control within your home during internet outages. However, remote voice commands via phone apps require internet. Wi-Fi-only locks revert to Bluetooth control when offline, which may disable voice features entirely. Always choose a lock with “offline voice mode” that stores critical voice commands locally.
2. Can voice assistants unlock my door without my permission?
No, if configured correctly. All major platforms require a voice PIN for unlock commands by default in 2026. Additionally, enable “presence verification” so unlock only works when your phone is detected at home. Some locks support “voice challenge-response”—you say “unlock,” the lock asks “what’s the third word of your passphrase?” This prevents accidental unlocks from TV commercials or visitors.
3. How do I prevent my neighbors from controlling my lock with their voice assistant?
Voice profiles are isolated to your account and devices. Your neighbor’s Alexa can’t control your lock unless you explicitly share access through the voice app. However, sound leakage is real—a neighbor shouting through an open window could trigger your lock. Enable “proximity gating” using UWB or Bluetooth beacons so voice commands only work within 10 feet of the door, preventing distant activation.
4. Will my lock understand me if I have a cold or accent?
Modern locks use “vocal robustness training” that accounts for congestion, age-related voice changes, and accents. During setup, read provided phrases that include nasal sounds and varied pitch. The lock creates an “accent-adaptive model” that updates with each command. If accuracy drops below 90% when you’re ill, use the app’s “temporary voice mode” that relaxes matching thresholds for 24 hours while maintaining security.
5. What happens if someone records my voice and plays it back?
2026 locks defeat recordings through liveness detection. They emit ultrasonic pulses and analyze the Doppler shift unique to live vocal cords. Recordings lack this physiological signature and are rejected. Additionally, “audio watermarking” embeds inaudible signatures in your voice during enrollment; the lock verifies this watermark in real-time. For maximum security, enable “multi-factor voice” requiring a spoken PIN plus voiceprint match.
6. Can I use multiple voice assistants with one lock?
Yes, via Matter multi-admin. A single Matter-certified lock can pair with Alexa, Google, and Siri simultaneously, each maintaining separate voice profiles and permissions. However, command conflicts can occur—if you say “lock the door” within range of both an Echo and Nest Hub, both may respond. Use “assistant priority” settings in the Matter controller to designate a primary voice platform per room, preventing duplicate responses.
7. How often should I expect firmware updates for voice features?
Leading manufacturers release voice model updates quarterly, with critical security patches within 48 hours of vulnerability disclosure. Subscribe to the manufacturer’s security mailing list. In the lock’s app, enable “automatic voice model updates” but set a “stability delay” of 7 days—this waits for early adopters to test updates before installing them on your lock, balancing new features with reliability.
8. Do smart locks slow down emergency egress?
No—ANSI Grade 1 requires single-motion egress. Voice-enabled locks maintain traditional manual operation; the deadbolt turns freely from inside regardless of electronic state. In fact, some locks offer “emergency voice egress”—shouting “open sesame” during a fire (when smoke prevents reaching the door) triggers immediate unlock. This uses a loudness threshold, not voice matching, ensuring anyone can exit.
9. What’s the environmental impact of always-listening microphones?
Energy consumption is minimal—about 0.5 watts, comparable to a nightlight. However, the manufacturing impact matters more. Look for locks with “carbon-neutral voice modules” certified by the Carbon Trust. Some brands offer “eco voice mode” that disables always-listening, requiring a button press before voice commands, cutting power draw by 80%. Solar harvesting models can achieve net-zero operation in moderate climates.
10. Can I take my smart lock when I move?
Yes, but voice training data doesn’t transfer easily. You’ll need to factory reset the lock, erasing all voice profiles, then re-enroll at the new location. Keep the original mechanical keys and strike plate. Some manufacturers offer “voice profile export” that encrypts and transfers your voice model to a new device, but this is rare due to privacy concerns. Consider the lock a “semi-permanent” fixture—its value proposition is strongest when installed for 5+ years.
