Which Ignition Lock Cylinder

[drdave81]

The lock cylinder seems to be going out on the 01 Yukon Denali I just bought. You have to roll the key around up/down/back/forth, etc until it finally turns. The vehicle only came with one key that is pretty worn down. I was going to replace the lock cylinder and just have two keys, not a big concern, but there are multiple options. There is one (currently available at the parts store, and cheapest) without an accessory position, one with a thumbwheel but doesn't say with or without accessory position, or one with accessory position but is out of stock everywhere around me. I guess I don't necessarily need the accessory position, or wouldn't care about the thumbwheel, but I'm not sure if I could even use either of those. Would anyone have any idea if they're all interchangeable or not?

haven't head of any like that but beware there are some that cannot be re-keyed, so you would end up having to have 2 identical looking keys or have your door locks re-keyed to match the ignition key, it's probably more economical to pay a little more for a better ignition cylinder or get the oem and have it re-keyed than to have to take the door apart to have it re-keyed.

I had mine replaced by the GM dealer. They use your VIN to get the exact replacement and can cut the key the same as the old on. Was well worth the reasonable cost.

I'll call the dealer, see what they want for an ignition cylinder. I usually just use the key fob, so the other key (which is an aftermarket one already) for door lock-only wouldn't be terrible.

A locksmith could handle that too.

A locksmith could handle that too.

Can confirm. We recently suffered two attempted truck thefts. The thief busted both door locks and the ignition cylinder. My mechanic had the door locks and ignition cylinders keyed to the original keys by a locksmith.

I'll check in with a locksmith once I'm back in town too. Thanks guys

I just changed my cylinder and I opted to go with an OEM (I heard that sometimes aftermarket just don’t work as well) from https://www.gmpartsdirect.com/

Looks like yours would be about $50

In case anyone ever wants to go this route.......

I replaced the ignition cylinder with an aftermarket one. I'll keep the other key for doors, on the off chance my key fobs don't work.

When you look up the ignition cylinders, there will be an option for one with and without accessory position. Mine has an accessory position, but I was able to install the cylinder for a vehicle without an accessory position. I still have an accessory position when I turn the key. There is no perceivable difference. The part number I used was: Locksmart LC63200 from Advance Auto.
