4. Receiver acknowledges programming mode by the flashing Vehicle Theft Security System LED located on the top, center of the instrument panel.

NOTE: Program mode will time out If no valid transmitter code is received within 60 seconds. The timer resets after each successful transmitter programming.

5. Send transmitter code by pressing either button on the transmitter for approximately 10 seconds. A successful programming will be acknowledge with a horn chirp. Repeat for both transmitters. All transmitters MUST be reprogrammed anytime a new FOB is added.

TRANSMITTER RESYNCHRONIZATION
The Electronic Entry system has a rolling code for the RKE system. The transmitter and receiver increment together. If the transmitter buttons are pressed more than approximately 255 times out of range of the receiver, the transmitter and receiver are said to be out of synch. In this case the transmitter will no longer operate. The transmitter and receiver can be resynched by holding both the LOCK and UNLOCK buttons down for a period of 5 to 10 seconds. The receiver shall acknowledge a successful synchronization by commanding a horn chirp. Normal transmitter function will return.
