WEST917.GOAL-TXK, inspection and repair due to malfunction of entrance cylinder

"I can't lock it because the key won't stick"

It's a common problem during last night's stormy morning. There was a report that the entrance cylinder, which was in bad condition, suddenly stopped working.

The screw for fixing the pull-leg on the thumbturn side was also loose, and there was also a symptom that it would not turn when tightened.

When I disassembled it and searched for the cause, the cylinder was due to aged deterioration (dirt), and I was able to improve it by cleaning and lubricating normally.

The wrong screw was used by the vendor that installed the pull-leg screw. It could be improved by changing to the correct retaining screw, but it seems that the WEST TX cylinder did not match the door thickness in the first place and remained as it was. The tailpiece seemed long.
