One of my key fobs battery is about dead. If I crack it open and put a new one in, do I need to reprogram it?

Will I have to reprogram both of them?

 

You will likely have to resynchronize it. You shouldn't have to do both unless you replace both batteries.

The manual for my 97 says

"Try to resynchronize the transmitter by pressing and holding the LOCK and UNLOCK buttons for seven seconds when standing next to the vehicle." This will attempt to resynchronize the security code in your RFA key fob transmitter.

When resynchronization is achieved the horn will chirp. If attempts to resynchronize your transmitter to the vehicle are not successful, you man need to match the transmitter to the vehicle.


To match the transmitter to your vehicle:

1. Turn the ingnition key to the ON position
2. Clear any warning messages on the Driver Information Center (DIC) by pressing the RESET button.
3. Press the OPTIONS button on the DIC several times until the blank page is displayed, then press and hold the RESET button for two seconds.
4. When the message FOB TRAINING is displayed, push the RESET button once. The message HOLD LK+UNLK 1ST FOB will be displayed.

5. Press and hold the LOCK and UNLOCK buttons on the transmitter simultaneously for 15 seconds.

6. When a transmitter is learned, the DIC will display FOB LEARNED and then prompt you to learn the next transmitter.

7. Repeat steps 5 and 6 for each additional transmitter.

8. Remove the key from the ignition.

The programmer mode will shut off if:

You don't program any transmitters for two minutes.
You take the key out of the ignition.
You have programmed three transmitters.

Hope this helps.

There are very brief instructions imprinted on the inside of the remote transmitter case. They basically say to hold the Lock and Unlock buttons simultaneoulsy; if this fails, you'll have to go to Plan II, the details that Talon posted.

 

You will have to match it to the car again. Owners manual should tell you how.

 

Thanks for all the help, I am sure I will get it working.

 

All done!
