Transmitter Synchronization

IMPORTANT: Loss of transmitter synchronization will occur when the following conditions are present:
^ The batteries on the keyless entry transmitter have been replaced

In order to Synchronize a transmitter, press and hold the transmitter LOCK and UNLOCK buttons simultaneously for at least 7 seconds. The horn will sound when the synchronization is successful.
