ed-Lock PLUS Irritated battery cover Interlock unlock

"I replaced the battery, but the lid cannot be removed."

Is the phenomenon that the lid cannot be removed a problem with ALPHA's electronic lock ed-Lock system?

When we arrived at the scene, it was a current model ed-Lock PLUS (ed-Lock PLUS) electronic lock with an emergency cylinder. (It's been a while, I wonder what I'll do...)
Looking at it, the LA-based lock has been completely changed from MIWA U9.RA.The other room was U9.RA.It is said that the old lock was changed when moving in.

(It would be a big construction to make such a change, but it would be surprising to do so at a cost. The interior looks like it has been renovated, so to make it a popular property with an electronic lock. The management company told me that the owner had invested. It's 34 years old, but it's a polite job.)

When I interviewed the client about the situation, he said that although the battery still remained, the lamp indicating replacement came on after two years had passed.I tried following the instructions on the door, but the cover was so hard that it wouldn't come off.

(Usually, the cover interlock is forcibly bypassed, but the battery is still there, so I thought I'd just use the normal procedure to unlock it, as described in the manual.)

After all, it was the first time for me to follow the normal procedure, so I decided to try it according to the procedure manual. (But this was a mistake)

With the door open, the situation doesn't change even if I press and hold the 'start button'.If you operate it, it will be locked by automatic locking.does not move forward. (Is it necessary to enter the PIN seriously and proceed from the "unlock" operation? It's a very troublesome specification.)

I asked the requester to enter my PIN and proceeded with the operation, but it was reset while I was reading and confirming the procedure.
I will proceed with the second operation, but this time the timing to press the "start button" for the second time has been delayed.
Proceed with the third operation. (At this point, the frustration increased)

Enter the security code for the third time, and press and hold the "start button" within 3 seconds to change the lamp display. "Oh?!"

(There is no notation anywhere, but the "ST" display must be in the lower right corner. What if it is not written! MAX irritated at this point.)

At last, the interlock was released and the battery was replaced, but I thought it would have been better if the bypass was released obediently.I wondered why it was designed so difficult, but I will never operate it again!It is a reflection meeting.

In addition, when I checked it, I found that the emergency power supply battery terminal was not equipped depending on the type.This type with an emergency unlocking cylinder does not have an emergency power supply terminal.Only the cylinderless type has an emergency battery terminal.In the event of an emergency due to a power shortage, it would be better to unlock with batteries rather than making a duplicate spare key (5000 yen?/key) for the emergency cylinder key.
