Titan deadbolt lock

I have Titan deadbolt locks on three (3) doors in my house.

Of the three, the one on the front door gets the most use (and abuse).

It was getting more and more difficult to insert the key, like it was "gritty" inside the lock.

I put a little Liquid Wrench on the key, inserted the key, and turned the lock back and forth a few times.

Repeated treatment three times.

It made all the difference in the world. The lock now works just like it did when it was brand new.
