Usage Method:
Alarm Mode: Open the packaging, insert the key to open the lock, pull out the lock frame and rotate it 180 degrees, then insert it back into the lock body. When you hear the 'ding' sound, the alarm mode is activated. In this mode, if there is external force touching the lock body, the lock body will emit a sharp and piercing alarm sound. Normal Mode: Reverse the lock frame by 180 degrees again and press down. There will be no 'ding' sound as a prompt. The normal mode is activated. In this mode, no alarm sound will be emitted.
How to Replace the Battery:
Each lock comes with a set of batteries. Pull out the lock frame, unscrew the screws inside the lock frame, carefully open the bottom cover, and you can replace the battery. If there is no sound or the sound is not obvious, it indicates that the battery is dead.
