Hi all!
In my 99 Yukon, the ignition lock cylinder is wearing out. The key is loose in the cylinder, and I usually have to "shake" it a couple times to get it to start. Usually, it starts without a hitch. However, the plastic trim around the lock cylinder is all busted up...
So while I was at the junk yard today, I found a 2001 GMC Safari and it turns out my key somehow fit in the ignition cylinder perfectly and turned it like it was meant to be... I was amazed. A quick search revealed it was the same part number as the one my Yukon takes, meaning it should work. Anyways, I took the lock cylinder along with my other parts and was on my way.
When I got back and started installing parts, I pulled the old lock cylinder without any problems, dropped the new one in and... nothing. It wouldn't turn past the off position no matter what I did (FYI I'm fairly certain my passlock system has already been bypassed and even so, I don't think it would stop it from turning at all). I tried everything short of pulling the wheel to get it to turn... eventually I just said forget it, and drilled it out and removed it. I was able to start the truck with a large screwdriver (no lock cylinder at all), so my ignition switch is still good.
I then proceeded to drop the old one back in (I kept the key in the cylinder and everything). I installed it while it was in the run position, I cranked it back to off, and when I went to crank it on... nothing. I can jiggle the cylinder a little bit, and push it in and out, but it doesn't turn at all... the same thing as putting the wrong key in. I tried a couple of other GM keys (since the lock is worn out) and those didn't work either. Hours of searching left me nowhere.
TL;DR: Put new ignition lock cylinder in, wouldn't turn. Drilled it out, put old one back in, still won't turn at all.
Sooooooo...... any ideas? At the very least, how could I either remove the cylinder without drilling (and without the key turning), or get the damn key to turn?
Thanks!
