You can download C5 owner's manuals at the following web site:

Meanwhile, try the following in order:
Test the FOB batteries to insure they are good. Even newly purchased batteries can sometimes be bad.
Clean the battery contacts inside the FOB. A typing eraser, if you have one, works well for this.
Make sure the battery contacts inside the FOB are making good contact with the battery. Sometimes the contacts may need to be bent slightly.
Next, first try resynchronizing your transmitters as shown in the procedure below. If this doesn't fix the problem, then try the relearn or matching procedure below. Both of these procedures can be found in your owner's manual under Remote Keyless Entry and you may want to review that section of your owner's manual:
Resynchronizing Your Transmitter
Your RKE system uses a continually changing code for increased security. Normally, the receiver in your vehicle will keep track of this changing code. If your vehicle does not respond to your transmitter, do the following to determine what’s wrong:
1. Get closer to the vehicle and try pressing a button again. Your battery may be low. (If so, see “Battery Replacement” in the Index.)
2. While standing close to your vehicle, press the LOCK and UNLOCK buttons on your transmitter at the same time and hold for seven seconds. This will attempt to resynchronize the security code in your RKE transmitter.
3. When resynchronization is achieved, the horn will chirp.
Matching Transmitter(s) To Your Vehicle
(NOTE: You can perform the matching procedure on your own and do not need to go to a dealer to have this done.)
Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have only three transmitters matched to it. To match transmitters to your vehicle:
1. Turn the ignition key to ON.
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 in the DIC 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 (matched), 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 programming mode will shut off if:
Good luck

- You don’t program any transmitters for two minutes.
- You take the key out of the ignition.
- You have programmed three transmitters.
Good luck
