me and my neighbor just looked at this. He is a trained mechanic and teaches for UTI. He thinks that the best bet is to replace the ignition assembly. Looked like the ignition has been oiled and maybe the tumblers have stop catching.

is replacing the ignition a do it yourself job? It looks fairly simple. and i have my neighbor who could help me. but will this mess with the passlock system? Should a dealer mechanic handle ignition replacement.

 

i just read in another thread that a locksmith could maybe come out and replace the ignition on the spot? https://montecarloforum.com/forum/sh...ad.php?t=17467

 

i was able to call AAA and they sent out a locksmith. for $125, he was able to drill out the locked up ignition and up in a new module from a vendor of his.

 

did it fix it?? did you find out the exact problem??

 

the locksmith said he see's GM ignitions locked up frequently. He said he replaces them on newer GM cars usually around 50K miles.

 

common problem is the shifter gets shifted when people do stereos, and so you have to make sure its all the way in park, then try again.
