ALPHA ed-LockPLUS, battery cover does not open

"Inspection to ensure that the battery cover does not open"

Battery low was displayed on the LCD display.However, it seems that the unlocking operation is still possible.However, if I don't replace it soon, I can hear the motor not turning.

Even in that state, you may be able to release the battery cover interlock.Since a PIN was required, I asked the client to operate it, but the interlock could not be released.This type seems to be irritating.It won't open even if I follow the instructions.Moreover, the operation guide was not pasted on the door.In this case, the user cannot operate it.

Therefore, I removed the cover with bypass release.There was also a contact failure in the terminal part, but it has been resolved.

This is the type that always fails to open even if you follow the operating guide.
