Unlocking and repairing electric locks for ward-operated condominiums MIWA AL02

"I have the key, but the door doesn't open."

I left the room with the key to get rid of the garbage in the morning, but the key didn't work.The client is an elderly person, and it seems that there are many elderly people in this condominium in particular.The chairman of the management union has contacted me.

I thought it was a malfunction of the cylinder, but it looked like an electric lock that was locked automatically.When the key is inserted and turned, the cylinder turns but does not seem to unlock.

If you check from GAP, you can see the single slow stroke dead & latch bolt and the trigger latch.However, the GAP is 8mm or more.

(In the catalog specifications, "(Note 1) Keep the gap between the door and frame within 6mm.], it is thought that the trigger latch was not working (the door was open) due to the too wide gap, and the operation was unstable.)

I pushed the trigger latch with a pick and turned the key to unlock it.After that, adjust the gap, but bite the plate of the strike with a spacer and adjust it to a gap of about 3 mm.

The strike is also fitted with a magnet, but this is an electrical switch (for solenoid switches), so it doesn't make sense in this house, which is used without electricity.

It is said that this condominium has introduced an electric lock so that it can be used for handicap in the future as well as for wheelchairs with barrier-free specifications.However, the wiring is free and has not been connected yet, so it seems that the system has stopped halfway through.
