PROTECTO KEYED??

Sometimes called construction keying, it can cause your own keys not to work. The other day as one time this last year the key would not enter the lock fully. What I found when taking the lock apart was that several of the wafer thin master pins used had bound in the pin hole. Thus not allowing the lock to properly function. Part of the problem was also the use of both graphite and an oily lubricant like WD-40, causing the lock to be gummy. It was the combination that caused the gumming in the lock.

Solution remove the master pins and degrease the lock and reassemble.

Just like new!
