I have had a search and i can't find anything with the answer i am after so i thought i would ask.
I had a filing cabinet on which the key was lost and the user had in their wisdom tried to open the lock with some random instruments, safe to say they has messed the lock up pretty bad and there was no way it was going to be picked.
I was unsure of where to drill to open the lock, i assumed it would be essentially where the shear line is, just above the keyhole.
What i did instead which worked but was a pain in the rear to do was drilling right into the centre of the lock and in the process destroy every pin that was in the lock until the lock opened.
My question is this, is this the correct way to open a lock by drilling it?
I suppose it doesn't matter as long as you get in.
Excellent forum by the way.
