FAQ
Do smart locks work if the Wi-Fi goes down?
Yes. The keypad, fingerprint reader and physical key keep working locally. You only lose remote control and notifications until the connection returns.
What happens when the batteries die?
All four locks warn you in the app well before the battery runs out, and all include backup physical keys. The Tapo DL110 uses a rechargeable battery you top up over USB-C.
Will a smart lock fit my door?
Most fit standard US deadbolt doors. Schlage lists doors 1-3/8 to 1-3/4 inches thick with a 2-3/8 or 2-3/4 inch backset; check the compatibility guide for your model before buying.
Are smart locks secure?
Good ones use encrypted connections and tamper alarms. The Schlage Encode carries the highest residential BHMA rating for security and durability, and the eufy C220 is BHMA Grade 3 certified.
