the lock still wont turn. Security thing.

After awhile, the correct ket will work. Must be on a timer.






Nope...no such thing....the actual physical key cylinders on these are very basic things....no trick timers or locks or anything of the sort
You are on your way to experiencing the very thing this post was about....you have a cylinder wearing, due to a obvious different "cut" on your other key, it is pushing one or more tumblers past the "normal" range of movement that the correct key uses and it has them catching on a burr or thickened lubricant that is used in the cylinder.
