Remote Keyless Entry Systems: Programming: RESYNCHRONIZATION

  1. Resynchronization may be necessary due to security methods used by Remote Keyless Entry (RKE) system. Transmitters do not send the same signal twice. RCDLR will not respond to a signal it has been sent previously preventing recording and playback of transmitter signal. Resynchronization will be necessary if any of the following occur:
    • Transmitter battery is very weak.
    • Transmitter battery is changed.
    • Vehicle battery is very weak.
    • Vehicle battery has been low or not charged for an extended period of time.
  2. To resynchronize transmitter to RCDLR, stand within 5 feet of vehicle and simultaneously depress and hold LOCK and UNLOCK buttons on transmitter for 7 seconds. Door locks should cycle to confirm resynchronization.
