I found dieselgiant's write up on how to replace the cylinder if you can't turn the key. I just wanted to know how to replace it if you could. I am contemplating buying a cylinder from the dealer so that my door key and my ignition key match. My cylinder has been replaced by some cheesey aftermarket unit.

Hypothetically, if the cylinder were to fail, do I just stick a drill bit in the center of it and go at it? I have a good set of carbide bits, will that do? Also, had anybody tried brute strength to break it? That is sticking something like an offset screwdriver in it and applying a lot of force. I once talked to a guy who claimed to have experience with such things that said it had never failed him. Of course, all he cared about was that the car started.

EDITed for grammar.
