Ive changed out locks a few times and im kinda thinking with a 32oz hammer or so I could prolly knock alota these "locks" out one way or another. Never tried really really would love too!
A few years back we had a small fire in one of the buildings we were fixing up to rent out. The fire department got in the front door no problem, but by the time I got there they were beating the crap out of the lock on the back door with the back of an axe trying to get in. Apparently they first tried prying it with the halogen tool and still couldn't get in.
I walked over with a broken piece of hacksaw blade I had on the dash of my truck, slide it between the latch and the striker, and popped the door open just as fast as if I had used the key.
Brute force works, but sometimes you don't even need to work that hard. A little imagination goes a long way.
