Hybrid card lock malfunction repair for MC25 MIWA LA

"Cannot be locked with a card key."

After hearing, it seems that locking and unlocking was gradually becoming impossible.It means that the number of malfunctions is increasing day by day.

Considering this, I thought that the operation of the pins and mechanical mechanism would be slowing down due to deterioration over time.

Open the cover to expose the card reader and observe the movement.The arm part moves, but it is not locked.Therefore, it took 5 minutes to clean the lock arm, clean the pins, and wait for a smooth operation.

The movement of the lock arm is as small as a few millimeters, but it triggers the locking and unlocking operation, so it must be operated firmly.I forgot about it with MC25 after a long time, but I remembered it while working.

When this operation is not stable, it is necessary to remove the mechanical part in earnest and disassemble and inspect it, but this time it was not necessary.
