Does the Aqara Smart Lock U50 replace my entire lock?
No. The U50 retrofits onto your existing deadbolt, allowing you to keep your current exterior hardware and keys.

Yes. You can generate temporary or scheduled codes through the Aqara app for guests or short-term access.
Does the lock support smart home automations?
Yes. It can trigger routines such as locking doors at night, turning on lights when unlocked, or sending alerts when access occurs.
What happens if the batteries run low?
The lock provides low-battery warnings and supports emergency power options so you can regain access if batteries are depleted.
