Thread: Is the ignition key the same as the door key in a 2004 grand prix?

I have a 2004 grand prix and the key has never been able to unlock the door. I bought this car in 2009 so I am not the original owner. The ignitian key works for the glove box, trunk and to start the car but not for the door. My remote for unlocking the doors is not working at times and I have to climb through the trunk to get in the car at times. It is a real pain. Is there a seperate key or is there something wrong with my lock. I read somewhere that it dries up over time from not using it and to spray wd-40 inside to lubricate is this right?

bjornbjorn,

The key can be used for the ignition, as well as the driver’s door lock and storage compartments.

You may want to try WD-40. If that doesn't work, consider have a certified tech take a look at it.

Keep us posted.

Possible that the door might haved been changed all together but likely just seized up. Check the sticker inside the door by the latch and see if the vin numbers match up and let us know.

I'm guessing your door lock seized up like my trunk lock was. I had an 04 and the trunk lock never turned. It turned out to be a little corrosion. I removed the lock cylinder and tapped it with a small hammer to break the corrosion free and shot some white lithium grease in there to keep it from happening again. Haven't had a problem since. I check them from time to time not using the key fob as well so as to make sure they aren't freezing up.
