I recently got a 2004 zq8 crew cab. The key does not fit the door. Ot fits the ignition and tailgate. The door was never replaced. When the original owner figured out the key did not work on the door, the dealer refused to fix it.

Does anyone ha ve any ideas on how to get s key for the door? The fob works but if the battery were to die. How can you get in the truck?
Thanks for any ideas.

I talked to a couple of locksmiths. They will only work on making a key if I remove the lock myself.

Do you have any idea which locks are original to the truck? It appears that the door may have been replaced with one from salvage and the lock not switched.

If the door lock is original to the truck you could take your vehicle title to a Dealer and they could cut a key from a code they keep in the computer. You would then have two keys, but at least be able to open the door.

If the lock is not original it will need to to be removed to be re-keyed.

How to accomplish that would depend on a few choices, based on whether the truck is a daily driver or can be parked for a few days.

1. Daily driver: If you know someone that has some mechanical skills you could have them remove the handle assembly and replace it with a cheap one, without a lock cylinder, from RockAuto/Amazon. PN 25875521. Then you would have a useable locking door. Same situation you have now. Then you could have the lock re-keyed without having the truck parked. Cost for that would be about $20 in addition to the locksmith charges. If you can't do the work yourself and don't know anyone that can help, an auto repair shop might do it. Then you have more down time.

2. Non-daily driver: Same as above, but you don't have to purchase a handle. Not positive, but you should still be able to lock/unlock the door with the remote if the handle is removed. However, the door would have to be opened from inside.

Note: Might be a good idea to contact a locksmith prior to doing anything and make sure they have the lock cylinder tumblers for your truck. The tumblers are not the same as GM uses for most of their vehicles. They could probably make a key to fit that lock, but re-keying would be preferable and not much more work for a professional locksmith.


Keep us posted.

Thank you for the info and ideas. I know the history of this truck. The door was never replaced. The key just does not fit the truck door. I think when it gets warmer. I will park the truck in a secure location. Open the door, remove the lock and get a key made for this lock. My concern is (what if my battery dies)??? How do you get in the truck then?

The hood can be opened from outside. It is a little tricky the first time. Looking through the grille, above the bowtie emblem, you will see the face of the hood latch. In the center of it there is a bolt head. Just above, and to the right of it you will see a square shaped opening and a space where you can get a screwdriver behind the silver colored latch hook. Move it to your right and the hood will unlatch.

This key combination is not making much sense. How would a key fit the ignition and the tailgate, but not fit the door? I remember some years ago there were a couple of cases where the door lock cylinder would not turn, even with the correct key. It was due to the cylinder seizing from non-use. The Owner's always used the remote. If that might be the case with your lock, maybe try to free it up with some WD40.

I will try that. I know it was never used for a long time before it was tried. I will try some wd40 this weekend. Hope it works. 🙏

Keep us posted. Thanks.

I speayed wd40 in the lock and nothing. I am going to try again later or tomorrow after it has had time to sock in and loosen things up. Still hopefully.

I called the dealer about a new lock for the door. $100 plus another 12 for a key. But still have to take to a locksmith to set the lock to match the colorado. Just looking at options.

Yeah, you might have to work at it a bit. The part number for the lock cylinder is 89022371 . You can search for a better price. Ebay has them for about $75, but you have to scroll through all the garbage to find them.

I have sprayed wd40 in the lo c k 3 days now. Still cannot turn the key. I feel like the key may not be going in a the way. Like it's maybe a 1/4 inch shy of going in.

Might try 'lightly' tapping on the key? If you don't have a spare key it might be a good idea to get one and make sure it works in the ignition before tapping on one of them. You don't have to worry about the lock because it isn't working now anyway.
