Transmitter Synchronization
Resynchronization may be necessary due to the security method used by the remote keyless entry system. The transmitter does not send the same signal twice to the remote control door lock receiver (RCDLR).
The RCDLR will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter.
Resynchronization may be necessary under the following conditions:
The battery in the transmitter is very weak.
The battery in the transmitter was replaced.
The battery in the vehicle has been in a low or no charge condition for an extended period of time.
In order to resynchronize the transmitter with the RCDLR, perform the following steps:
Stand within 1.5 m (5 ft) from the vehicle.
Simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for 7 seconds.The door locks should cycle in order to confirm resynchronization.

Transmitter Programming
Start with the ignition OFF, hold down the power unlock button on the door panel. Turn ignition key ON, OFF, ON, OFF. Release power unlock button on the door panel. The locks will cycle once.
Hold down the keyless entry transmitter LOCK and UNLOCK buttons for 15 seconds. The locks will again cycle once.
Repeat step #2 for each additional keyless entry transmitter.
Turn the ignition on to exit the keyless entry transmitter programming mode. Programming is now complete.
