Best Smart Locks
Compare premium deadbolts, retrofit locks, fingerprint keypads, Apple home keys, Matter over Thread, guest access, and emergency entry. This guide compares real products and platforms, explains the tradeoffs that matter in daily use, and separates useful automation from features that add cost without improving reliability.
Schlage Encode Plus is the best conventional premium deadbolt for built-in Wi-Fi, keypad access, Apple home keys, and established lock hardware. Aqara U200 is the strongest retrofit option for fingerprint access and Matter over Thread. Level Lock Pro is best when exterior appearance matters, while Ultraloq Bolt Fingerprint is a practical biometric choice.

Security Starts With the Door and Installation
A smart lock cannot correct a misaligned door, weak strike plate, loose frame, or poor deadbolt installation. Before comparing apps, make sure the bolt extends without rubbing and the door closes consistently.
Choose hardware from an established lock manufacturer, use long strike-plate screws where appropriate, and retain a tested emergency entry method.
- Correct door alignment first.
- Confirm backset, bore size, door thickness, and handing.
- Use a physical key or external emergency power option.
- Test every entry method before removing old keys.
Schlage Encode Plus
Schlage Encode Plus combines a conventional keypad deadbolt with built-in Wi-Fi and Apple home keys. Schlage states that it supports up to 100 access codes and works with Apple Home, Alexa, and Google Home.
It is a strong choice for homeowners who prioritize lock hardware, straightforward guest codes, and no separate Wi-Fi bridge.
- Best for conventional replacement installs.
- Strong Apple Home Key support.
- Built-in Wi-Fi simplifies remote access.
- Larger exterior footprint than invisible locks.
Aqara U200
Aqara U200 is a retrofit lock that keeps the existing exterior key cylinder on many compatible doors. The separate keypad adds fingerprint, PIN, NFC, and Apple home keys, while Matter over Thread connects it to supported ecosystems.
A Matter controller with a Thread border router is required for third-party Matter integration. Installation quality and calibration are critical.
- Best retrofit feature set.
- Fingerprint and Apple home keys.
- Rechargeable lock battery with separate keypad power.
- Requires careful compatibility and Thread planning.
Level Lock Pro
Level Lock Pro hides most smart hardware inside the door, preserving a conventional exterior appearance. It supports Apple home keys and Matter over Thread, with remote access through a compatible hub or bridge.
The design is attractive, but price, door fit, radio strength, and battery access deserve more attention than with a conventional keypad lock.
- Best visual design.
- Matter over Thread built in.
- Apple home keys and touch access.
- Premium price and fewer visible backup controls.
Ultraloq and Yale Options
Ultraloq Bolt Fingerprint models emphasize biometric entry and multiple backup methods. Yale Assure Lock 2 offers several keypad and connectivity configurations, making exact model selection important.
Never assume two locks with similar names support the same platforms. Verify the radio, keyway, fingerprint reader, Wi-Fi bridge, Matter support, and included accessories.
- Fingerprint is convenient for families.
- Keypads simplify temporary access.
- Model-specific compatibility must be verified.
- Avoid relying on auto-unlock as the only entry method.
Battery Life, Access Codes and Failure Planning
Battery estimates depend on radio type, temperature, door alignment, motor load, and daily use. Thread and Bluetooth can be efficient, while direct Wi-Fi generally draws more power.
Create named codes for family, cleaners, contractors, and guests. Remove expired access promptly and avoid sharing one permanent code with everyone.
- Replace batteries before critical warnings.
- Keep mechanical keys outside the locked home.
- Use time-limited codes when supported.
- Review activity history and administrator permissions.
Final Verdict
Schlage Encode Plus is the best conventional premium deadbolt for built-in Wi-Fi, keypad access, Apple home keys, and established lock hardware. Aqara U200 is the strongest retrofit option for fingerprint access and Matter over Thread. Level Lock Pro is best when exterior appearance matters, while Ultraloq Bolt Fingerprint is a practical biometric choice.
Build gradually, test every automation, keep manual controls, and document the accounts and hubs that make the system work. A smaller reliable setup is better than a large collection of devices that depends on fragile integrations.
