MIWA-WEST917.MM, KagiLost key, Unlocking the entrance door

"Lost key, Unlocking the entrance door and cylinder replacement"

It was a 41-year-old old apartment in front of the station, and it was a 9-story pencil apartment.It was a request to unlock and replace the cylinder, but I was wondering if it was a knob.

When I arrived at the site, I was surprised at the narrowness of the site, but the location in front of the station is quite good.Remodeled and renovated rooms were sold second hand.

Well, unlocking was completed with normal thumbturn unlocking, but when I checked the actual product, it was MIWA MM lock.This is also rare.

WEST917.MM was attached, but since there is no spare key, the cylinder will also be replaced.

MM cylinder replacement method requires some attention.After sufficiently loosening the set screw on the front part, tilt the cylinder by 45 degrees to remove it, and install it by tilting it by 45 degrees.I don't know why it was designed this way.

For cylinder replacement, we chose KABA-ACE MM compatible product.
