Replacng Ignition Lock Cylinder

[Pegger204]

I have a 2000 Silverado, my key won't turn at all, I've already bought a replacement cylinder for it but cannot remove the old one. I have the steering column apart and I know that I need to turn the key and depress the locking pin on the cylinder......

 

Sooooo anyone know how to replace it without being able to turn the key?

 

Thanks

Here try this link to a previous 2000 and 2003 may be of the same seed (I personally have not changed one in anything newer than a 97. Lots of additional info regarding air bags and such.

Have you tried to release the tab even though you can turn the key. I have never had to replace one where the key was stuck and wouldn't turn.

 

Also have you tried to remove the ignition switch and then see if the lock cylinder will turn?
