Transmitter Synchronization

2002 Chevrolet Impala LSSECTION Transmitter Synchronization

Synchronization may be necessary due to security method used by remote keyless entry system. Transmitter does not send same signal twice to Remote Control Door Lock Receiver (RCDLR). RCDLR will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back signal from transmitter. Resynchronization may be necessary when, battery in transmitter is very weak, battery in transmitter was replaced, or battery in vehicle has been in a low or no charge condition for an extended period of time.

In order to synchronize transmitter with RCDLR, perform following steps:

  • Stand within 1.5 m (5 ft) from vehicle.
  • Simultaneously press and hold LOCK and UNLOCK buttons on transmitter for 7 seconds.
Horn will chirp in order to confirm synchronization.
