For 1990-2009 cars

• | Resynchronization may be necessary due to the security method used by the remote keyless entry system.

| The transmitter does not send the same signal twice to the body control module (BCM).

• | The BCM will not respond to a signal that has been sent previously.

| This prevents anyone from recording and playing back the signal from the transmitter.

• | The fuel door release button should still operate normally when the system is out of synchronization.

• | Resynchronization may be necessary under the following conditions:

- | The battery in the transmitter is very weak.

- | The battery in the transmitter was replaced.

- | The battery in the vehicle has been in a low or no charge condition for an extended period of time.

• | In order to resynchronize the transmitter with the BCM, perform the following steps:

1. | Stand within 1.5 meters (5 ft) from the vehicle.

2. | Simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for 7 seconds.

The door locks should cycle in order to confirm resynchronization.
