Default Retarded GM Key Fob

Key fob is not working right on our Bravada. You push the unlock button and it locks the doors, you push the lock button and it sets off the panic alarm...wtf? We just installed a new battery last month and never had a problem until yesterday...do you think the Key Fob is bad or could it be something wrong with the truck?

Did you reprogram it ? If you don't do it exactly right it can mess it up.

This is a procedure for a 98 bravada


With the driver door closed, hold down the power unlock button on the door panel.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Turn the ignition switch to the ON position.
Turn the ignition switch to the OFF position.
Release the power unlock button on the door panel. The remote control door lock receiver will respond in the following manner in order to indicate that the receiver is in the programming mode:
6.1. Locking the doors
6.2. Unlocking the doors

IMPORTANT: All extra transmitters must be programmed at this time. When a new transmitter is programmed, it will deactivate the old transmitters.



Hold down the lock and unlock buttons on the transmitter until the remote control door lock receiver will respond in the following manner:
7.1. Locking the doors.
7.2. Unlocking the doors.

Repeat step 7 for each additional transmitter.
Turn the ignition switch to the ON position in order to exit the transmitter programming mode.
In order to reprogram the remote control door lock transmitter with a scan tool, refer to Scan Tool instructions.

It never lost the program when I changed the battery, our other fob did though. Dealer in town says they will program a new fob and if it works then we know it was a problem with the old fob , then we can purchase the new fob for $72. They said the contacts in the fob probably shorted out and they see that problem all the time.

I am going to try to reprogram our old one first before going to the dealer tomorrow...now do you program the second fob the same way or is there a different sequence so the vehicle knows it is the second fob? They are the smart fobs his/hers that control the power seats so it seams to me you would need to teach the vehicle which one is which?

the dealer will have a tool to test the signal from the fob, so there should be no need to get a new one until you are sure that one is bad. To reprogram the old ones, simply do the #1 fob first and then #2, that is how the car knows which one is which for the memory seats.
