My local dealership wanted to sell me a new key fob for $143.99. I went to www.carandtruckremotes.com and ordered a new button replacement pad for $9.95 and all of my buttons on the remote work now. No reprogramming required.

My husband was sceptical that this was the solution, but now he is a believer when we received them in the mail and replaced the button pad and it worked.

Great, inexpensive solution for an annoying problem.

The fab key it self may be bad at the unlock switch it self and the fab key needs to be replaced. You can try to reset the fab lock if you like and see if that addresses the issue. 
Important 
Once the Keyless entry receiver enters the programming/diagnostic mode, the programming of the first transmitter erases all previous transmitter programming information. You must then program all of the transmitters. 

Program only 1 vehicle remote control door lock receiver at a time. If you program multiple receivers simultaneously, the same transmitter could possibly be programmed to more than 1 remote control door lock receiver.

Perform the following steps:
Sit in the vehicle driver's seat. (actually it’s much err from the front pass seat) 
Remove the ignition key from the ignition lock cylinder. 
Close all of the vehicle's doors. 
Remove the MALL PGM fuse from the fuse panel. Refer to Electronic Diagnosis in Body and Chassis. 
Turn the ignition lock cylinder to the ACC position. 
Turn the ignition lock cylinder OFF, then back to ACC within 1 second. 
Open and then close any vehicle door. You will hear a chime when the remote control door lock receiver enters the programming/diagnostic mode. If you do not hear a chime, start again at step 1.

Important 
After 7 seconds, you may hear a chime confirming successful synchronization. After approximately 14 seconds, you will hear a chime confirming successful programming.

Press and hold the transmitter LOCK and UNLOCK buttons simultaneously for 14 seconds. 
Repeat step 8 in order to program each additional transmitter. 
Remove the ignition key from the ignition lock cylinder. 
Install the MALL PGM fuse back into the fuse panel. Refer to Electrical Diagnosis in Body and Chassis. 
Validate that all the transmitters that were programmed operate properly. Refer to Keyless Entry System Operation

Good luck and hope this helps. If you have problems you can try asking the service department at the dealer where you bought the car or where you have the car serviced. Simple things like this most of the time will not cost much and may even be free of charge if you have a good relationship with them.
Good luck and hope this helps.

Go to dealer and order new key fob you might be able to go to autozone to order for a little cheaper though!!!
if you go to autozone you will want to make sure you have the FCC id # off the control box located under the dash on the drivers side first!!

Door locks to side doors will not lock or unlock using either the key fob or door buttons. Back hatch will unlock using key fob


Check the fuse for the door locks first, then if nothing there look for a wiring diagram that shows the ground wire location and verify the ground is made. Also the driver side lock switch button could be the culprit

My doorlocks lock and unlock while driving and so im afraid its ging to engage the security feature to shut down fuel pump.i don't have a key fob.


Hi Jason:

We've had similar problems with our Aztek and Buick.
The problem was with the Body Control Module and was beyond my fixit skills.
The local GM dealer attended to it for a cost of approx $1,000 per vehicle.
Definite PITA
Hope you have better luck.

You have to go to a Chevy dealer. They have a hand-held computer they plug into your car to get it into programming mode. Probably cost $50-$60. Call them for an estimate.

Key fob unlock does not work


This happen with our 2006 Chevrolet Malibu Maxx LTZ. Open your fob and test the battery. If you measurement is not 3 volts; replace the battery. Our battery was fine, but my fob worked by pressing the circuit board directly. Bought a new case with rubber inserted my old fob board. works fine

Key fob remote start issues


You need to get one that works on the same wide range frequency as the reciever in the car, and then it's a simple matter of opening both the new and old fobs, and matching the fine frequency settings by putting the little switches inside where they should be according to the old fob's switches. If there are no switches in the old fob, it's preset and there's not much you can do about it.
