Alpha ed-Lock-Plus, battery replacement by removing the battery cover

"The touch panel does not work and the electronic lock cannot be used."

When I checked the photo on Google Maps, it looked like an electronic lock made by Alpha, KEIDEN, or MIWA.

It is possible that the lock is disabled due to the dead battery.

When I arrived at the site, there were multiple apartment properties with the same design on a large site.Each door has an electronic lock, but most of them are KEIDEN's "Fe-LOCK", which has many corrosion problems, and some are Alpha's "ed-Lock" and "ed-LockPlus".

The request was for the latest ALPHA ed-LockPLUS.

Unlock the battery cover bypass and replace the battery.It seems that the AA battery was replaced half a year ago, but it was a manganese battery with low performance.The client replaced the battery with a new manganese battery (?), but it did not work.

Daiso and top value manganese batteries are not suitable for electronic locks that require driving power for front doors.

As an operation check, it became normal operation with EVOLTA made by Panasonic on hand.The model this time was equipped with an emergency power supply terminal, so I will show you how to handle it and complete the work.Batteries are to be prepared by the customer.
