Smart locks can join routines, lock automatically when you leave, and let you check the door from anywhere. They also connect your front door to your home network, which deserves some thought.
How they connect
- Bluetooth: works from your phone near the door; usually needs a bridge for remote control.
- Wi-Fi: connects directly but uses more battery.
- Z-Wave, Zigbee, Thread or Matter: connect through a hub or compatible controller.
Useful automations
- Auto-lock a set time after the door closes.
- Notifications when a specific code is used.
- Locking at bedtime as part of a routine.
Settings to check
- Require a PIN or phone confirmation for voice-assistant unlocking.
- Enable two-factor authentication on the lock's account.
- Review who has access in the app periodically.
- Keep firmware updated.
Physical basics still apply
The bolt must slide freely into a solid strike. If the door binds, the motor struggles and batteries drain. Keep a mechanical backup.
Connection options
Locks may connect through Bluetooth, Wi-Fi, Z-Wave, Zigbee or a manufacturer's hub. Each has trade-offs for range, power and reliability. Wi-Fi locks use more battery. Hubs add another device that can fail.
Automation with care
Useful automations include locking at night, notifying you when a door opens and giving time-limited codes to guests. Avoid automations that unlock the door automatically when your phone is near, unless you accept the risk.
Security basics
Use strong account passwords, turn on two-step verification and update firmware. Check whether the lock works if the internet goes down. See phone-as-a-key locks and biometric locks.
A sensible first setup
Begin with the lock alone for a few weeks before adding automations. Learn how it behaves when batteries are low, when the wifi is off and when two people use the door at once. Then add one automation at a time, such as an evening lock reminder. This avoids the situation where a change breaks entry for the whole household on a busy morning.
