Remote Keyless Entry Transmitter Synchronization
Resynchronization may be necessary due to security method used by Remote Keyless Entry (RKE) system. RKE system uses rolling code technology. Transmitter does not send the same signal twice to remote control door lock receiver (RCDLR). RCDLR will not respond to a signal that has been sent previously. Resynchronization may be necessary under the following conditions:
- Weak transmitter battery.
- Battery in transmitter was replaced.
- Vehicle battery has been in a low or no charge condition for an extended period of time.
- Stand within 5 feet (1.5 meters) from the vehicle.
- Simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for 7 seconds. Horn should chirp in order to confirm synchronization.
