GM Six-Cut Tip

Generating a working door key for a 6 cut GM is easily accomplished by pole in the glove lock. The glove box lock, as many locksmith technicians know, gives four of the six cuts then I progress the other two. What can be difficult is popping the plug out of the “squeeze type” locks. 

Here’s what works quite well for me: I clamp the whole lock case in a vice with the bottom of the plug facing up. Of course I’m careful not to crush the plug. With my rick retaining ring pliers, I spread the plastic tabs which lock into grooves on the sides of the plug-ins for those tabs as far as possible. Next, I use an automatic center punch to pop the plug out. It’s a quick way to do that and doesn't damage the tabs.
