GOAL V.PXK＋SK-TMB+TM, inspection and repair of cylinder defect

"Hard to turn the key"

The request was to check for a defect in one lock in a tower apartment in the suburbs. I wonder if there is a single lock in the tower apartment. I think it's a double lock, but I'll check it out on site.

As expected, it was GOAL's push-pull grip handle lock GOE type. The cylinder was only getting a little stuck, so I usually fixed it by spray cleaning. There was no need for an overhaul.

As for the security thumbturn, the upper side is the TMB type that spins idly, and the lower side is the TM type that is eccentric, so if it is a double lock, it will not be easy to unlock them.
