Smart Locks
Choose a smart lock for a specific access task: giving a guest a code, checking lock activity or locking remotely. Confirm those functions on the exact model and app configuration. Door fit, battery failure and account recovery deserve as much attention as the unlocking method.
- Sharing access? Check individual guest codes, their permitted times and how to remove them.
- Need remote control? Confirm the network, hub, app and account requirements before buying.
- Check the door and frame separately: confirm the lock fits and the bolt moves freely without pushing or pulling the door.
What smart locks actually do
Smart locks offer different combinations of keypad, phone, fingerprint and physical-key access. A feature in the brand's app or another lock in its range may not be available on your model. Check local entry, remote control and activity history separately; they need not have the same connection requirements.
What to look for
Power and backup entry
Read the exact dead-battery entry procedure and keep the required backup accessible outside the locked home. Check battery type and low-battery alerts. A physical key is one option, not a universal requirement; some key-free locks use temporary external power plus a valid entry code.
Account access and recovery
Use a unique password and enable two-factor authentication where offered. Check how to recover access if you lose your phone, who has owner permissions, and how app and lock updates are delivered. Give guests only the permissions they need.
Auto-lock
Check the available delay settings and whether auto-lock uses a timer, a door-position sensor or another condition. Follow the setup instructions and test the behavior with your door. Choose a setting that suits your household; there is no universal two-to-five-minute recommendation.
Access log visibility
Ask which events appear, whether they identify a credential or only a manual operation, and how long records remain available. Check who can view or export them and what happens offline. A lock event is not proof of who physically entered the home.
Guest credentials
Confirm whether the model supports separate guest codes, scheduled or temporary access, and the number of credentials you need. Check how additions and removals reach the lock, especially when it is offline. Do not promise a visitor access until setup is complete.
Check these features on the exact model
- Fingerprint entry: check the supported operating conditions, enrollment instructions and alternative entry method. We have not measured recognition speed or failure rates.
- Integration: match the exact lock, radio or module, hub and app. Confirm the functions you need: locking, unlocking, status, guest codes or automations. A compatibility logo alone does not confirm every function.
- Tamper alerts: read what triggers the alert and whether it sounds locally, sends a phone notification or both. Check any connection requirements rather than assuming it prevents entry.
Two examples to check before buying
Backup entry: Yale's key-free Assure Lock 2 models YRD430 and YRD450 use a 9V battery at the exterior terminals to provide temporary power, followed by a valid entry code. This is a model-specific backup procedure, not a claim that every key-free lock works this way. Yale's Assure Lock 2 backup instructions.
Remote access and records: Schlage lists app pairing, a powered lock, home Wi-Fi and an internet-connected phone among the requirements for remote control of its Encode series. Its lock-history guide says the supported locks store history in the Schlage cloud and need stable Wi-Fi for real-time updates. Check the separate Apple Home requirements if that is the app you intend to use. Remote-control requirements · Lock-history requirements.
