snapped together tightly so water will not get in.
5. Check the transmitter operation. If needed, follow
the instructions on resynchronizing your
remote transmitter.
Resynchronization
Your remote lock control system uses a continually
changing code for increased security. Normally, the
receiver in your vehicle will keep track of this
changing code.
D
Loss of synchronization will occur if the transmitter
is activated more than 256 times while out of range
of the vehicle.
D
Loss of synchronization will occur after the battery
replacement if the transmitter is immediately
activated more than 16 times while out of range of
the vehicle.
If your remote lock control transmitter has stopped
working, you may need to resynchronize the transmitter
to the vehicle receiver. To do this, press the LOCK and
UNLOCK buttons together and hold for at least seven
seconds or until the horn sounds if equipped with the

Content Theft Deterrent system. Check the
transmitter operation.
