He is asking how to remove the lock, not by pass it or pick it. Restricted information

Is anyone gunna turn someone down if they ask how to remove a door knob from a house? Medeco or kwikset; I don't think so. You have to be on the right side of the door to properly remove these locks or it would be destructive entry and it don't take a friggen genius to figure out to kick harder!!!
If someone was going to break into a car, they wouldn't remove the lock to do it, as the vehicle would already need to be open to do it in the conventional ways.
If you look at a metal filing cabinet lock and how it is attached, that is the basics of how auto door locks are attached.
Look for junked cars where the windows have been removed as this means that someone has already done all the "hard work" for you. All the door panel, electrical and window will be gone leaving you super easy access to the lock. Pop the clip and your ready to go.
Look for junked cars where the window has been blown out. You can stick a prybar where the window slides into the door and pop the retaining clip without having to remove any door parts.
If you remove the lock from inside the door
wear gloves When you grab that retaining clip and try to slide it to the side it will not want to give. And then at the last second it will pop off and your gunna slam the back of your hand into the sharp corners of the internal door structures.
Lock linkages are held on in one of two ways. They are riveted together, in which you would want a pair of side cutters. Position the jaws of the side cutters in between the two pieces of metal riveted together and they should pop the rivet off. Or the lock linkage is in the form of a "Z" in which case you follow the lock off the linkage.
Also, ask prices before you go popping locks off. I would also suggest getting locks with keys as you can use the key as a map when learning to pick these locks.
I cannot tell you about ignitions as that is strictly bypass info. But you know what they say "The only way to truly learn something is to do it" Maybe you could learn stuff by playing around with them and then when accepted into the adv forum you could post what you have learned... Just a thought. (Junked car... it don't really matter if things get broken in the process.)
