For 1990-2009 cars

The keyless entry transmitters may become out of synchronization with the remote function actuator ( RFA) module under the following conditions:

• | When changing the transmitter battery.

• | Excessively pressing the transmitter buttons while out of the vehicles range.

When a transmitter becomes out of synchronization, only the panic feature will operate from the transmitter.

To resynchronize the transmitter, perform the following steps:

1. Hold the transmitter within the range of the vehicle.
2. Press and hold the transmitter LOCK (4) and UNLOCK (1) buttons simultaneously for 8 seconds.

When the transmitter is synchronized with the vehicle, the door locks will cycle. The horn will chirp and the exterior lights will flash if programed to do these functions.
