Both key fobs aren't working suddenly. Took it in to the shop to have some work done and now they don't work. The work done doesn't seem like it would interfear with the electrical? Any thoughts?

 

may have to reset them or check the batteries my luck would be batteries at the exact same time even though slim chance of it happening.

 

Both my batteries died within a week of each other.

 

Try a re-sync. Hold lock and unlock simultaneously till the horn beeps - about 10 second or so.

 

If your tire pressure sensors don't work also, then it's the remote transmitter behind the driver's seat.

 

success!!! Thank you!

 

The odds that both your Remote Keyless Entry transmitters had a battery failure at the same time are remote, get it, remote! I crack myself up. Anyway, I would try transmitter re-synchronization first and see it that corrects the problem. Good luck – Ed

Transmitter Programming/Synchronization

Each transmitter has a unique Vehicle Access Code (VAC) that changes every 5 seconds. If a transmitter or receiver is replace, each transmitter must be programmed to the vehicle's receiver. Entering a specific button sequence on the DIC, up to three transmitters can be programmed into the receiver. After programming the transmitters to the vehicle, the receiver will update this code every 5 seconds in order to match the code programmed in the transmitter.
The transmitter may not communicate or become out of synchronization with the receiver if any of the following situations occurs:
• The transmitter battery is disconnected.
• The vehicle battery is disconnected.
• The transmitter and the vehicle are separated for 2 weeks or more.
• The receiver is disconnected.
Perform the synchronizing procedure if the transmitter does not communicate or becomes out of synchronization with the receiver. If the transmitter and/or receiver are replaced, preform the following programming procedure:

Reprogramming

1. Turn the ignition to ON.
2. Turn the radio to OFF.
3. Press the RESET button in order to clear any IPC warning messages.
4. Press and release the OPTIONS button on the DIC to scroll through the display options until the
IPC display is blank.
5. Press and hold the RESET button for 3 seconds.
6. Press the OPTIONS button until FOB TRAINING message is displayed.
7. Press the RESET button in order to begin the programming sequence. The message HOLD LK + UNLK 1 ST FOB will be displayed.
8. Simultaneously press and hold the LOCK and UNLOCK buttons on the first transmitter for
15 seconds. The IPC will indicate when that transmitter is programmed and when to proceed to the next. Repeat this procedure for each additional transmitter or press the OPTIONS button to exit.

The receiver will cancel the programming sequence if any of the following conditions occur:
• The program mode is exited through the DIe.
• The ignition is turned to OFF.
• The three transmitters have been programmed.
• The RFA system has been in the program mode for longer that 2 minutes and not transmitters have been learned.
