Transmitter Synchronization
Loss of transmitter synchronization will occur when the transmitter is activated more than 256 times while the transmitter is out of range of the remote control door lock receiver. After the transmitter battery replacement, if the transmitter is immediately activated more than 16 times while the transmitter is out of range of the remote control door lock receiver synchronization will be lost.
In order to resynchronize the transmitter, press and hold the transmitter LOCK and UNLOCK buttons simultaneously for at least 7 seconds, or until the following condition is present, the horn sounds 3 times.
Perform the transmitter resynchronization procedure if the batteries on the keyless entry transmitter have been replaced or a keyless entry transmitter is malfunctioning.
