KWIKSET (Kwikset) TITAN (Titan) disassembly cleaning repair

"The key at the entrance is not working well, so please check it."

The key is hard and gets caught, so I want you to repair or replace it.

It seems that disassembly and cleaning is required this time.Although it has 6 pins when removed from the keyhole, it is a sidebar type like MIWA U9.It is a tumbler type cylinder, not a pin cylinder.

This is also a well-thought-out cylinder.

As for the work, it was improved with regular cylinder cleaning and lubrication.
