Door Locks

Yes, the DL2 has built-in Bluetooth and a physical key, so it keeps working when Wi-Fi drops, and the DL1 is a PIN keypad lock with a mechanical key override. The EZVIZ DL01S adapter unlocks locally over Bluetooth, and only its remote access and cloud notifications depend on the EZVIZ A3 Home Gateway, which is sold separately.

Yes, the EZVIZ DL01S fits over most standard deadbolts on the inside of the door with no drilling, so the existing lock and cylinder stay in place. It gives app and Bluetooth unlocking with auto-lock, and the kit version adds the DL01CP outdoor keypad for passcode and proximity card entry. Check your deadbolt against the compatibility list in the EZVIZ manual first.

The DL2 fits doors with a thickness of 35–65mm, and its listing says it fits most UK doors and installs with basic tools. Measure the door leaf before ordering. The DL1 lock body is 13mm thin and is listed for aluminium, wood, steel, stainless steel and brass doors.

A fail-safe lock needs power to stay locked, so it releases when the power is removed. The CDVI ML-350M-PL-12 mortice lock and the RGL DBGLS150 drop bolt are both fail-safe, and CDVI says its lock suits managed escape routes when used with appropriate controls. Confirm the fire and building regulations for an escape route with your installer.

Its listing describes it for domestic and commercial use.
