This ain't lockpicking, this is a method to avoid having to break out a halligan bar for firefighters. We don't carry shotguns, and the person on the other side of the door called 911 and is in a position to not be able to unlock the door. So, we open it quickly doing as little damage as we can. I'm not going to break out a set of picks and try to pick a lock when I can either do this, or if this fails, go through regular forced entry.

74KU - I guess quick and little damage is a relative team. I meant that it was quick and little damage as compared with conventional forcible entry techniques which would have destroyed the door, frame, knob, and framing around the door. As far as firefighting forcible entry is concerned, the $20 or $30 to replace the knob is little damage. I will admit that I mangled the knob pretty good in this instance, I have also performed this same technique with no damage at all to the knob.

I like the card threw the door method.

Dent puller works much better.

Shotgun the fucker. Seriously though.. quick and with little damage? I am a noob lockpicker and still I have not come across a knob in lock I can't pick almost as fast as using the key...
