I'm curious why you are changing it.
Just had one replaced on a 2003 Chevrolet 1/2 ton pickup. Couldn't turn the key at all.
My repair place actually brought in a locksmith to do the job.
There are several videos showing how to do it but after looking at it I decided to have someone else do it that knew what they were doing.
2004 Monaco La Palma 36DBD, W22, 8.1, 7.1 MPG
