Keyless Entry Transmitter: Testing and Inspection

TRANSMITTER PROGRAMMING

IMPORTANT: Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle. The order in which the transmitters are programmed is important. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. Use care to program the transmitters correctly.

The scan tool must stay connected until all of the transmitters are programmed.
