So the dealer just called today and said the lock cylinder housing needs to be replace on my 2001 Blazer. Anyone have a how to that can help me in replacing this myself? thanks.

 

im not quite sure what that means. if its in the door. you basically just have to take the door panel apart and unsnap the clip from inside and take it out if its like the older ones. and the ignition cylinder inside the steering shaft you need a wheel puller. i just did one the other day. hate it im always afraid im gonna brake something in there
