Transmitter Synchronization
TRANSMITTER SYNCHRONIZATION - DOMESTIC
Resynchronization may be necessary due to the security method that the remote keyless entry system uses. The transmitter does not send the same signal twice to the receiver. The receiver 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 transmitter battery is changed
^ The vehicle battery is disconnected
^ The transmitter buttons are pushed 256 times out of range of the receiver
In order to resynchronize the transmitter with the receiver, Stand close to the vehicle and 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.
