HI
i have just been reading a lock book and came across this lever lock where it has a detector lever. a lever that lets the owner know if the lock has been tried to open with false key or implement. the lock has a lever amongst other levers inside the lock that if someone over-lifts anyone of the levers they get caught and held up in the over-lifted position. and when the owner puts key in and doesn't turn like normal knows that someone has been trying to manipulate the lock.
do they still make these locks if so do you come across them much.
