If you power off a fingerprint lock without closing the lock during the use of
external power, the lock cylinder will not automatically return to its original position.
That is, the fingerprint lock remains in NO state. To solve this problem, you can
replace the battery and then open the lock once to have the lock cylinder in position.
4.6 Unlock With an Emergency Mechanical Key
You can open the door using an emergency mechanical key in case the electronic

(1) Pry open the keyhole cover by inserting the sharp end of a ball-pen or
screwdriver with a diameter of less than 3 mm. Remove the cover.
(2) Insert the emergency key into the keyhole and rotate 90° to unlock.
