Transmitter RESYNCHRONIZATION

  1. Resynchronization may be necessary due to security methods used by RKE system. Transmitters do not send the same signal twice (rolling code). Receiver will not respond to a signal it has sent previously. This prevents recording and playback of transmitter signal. Resynchronization will be necessary under following conditions:
    • Transmitter battery is very weak.
    • Transmitter battery is changed.
    • Vehicle battery is replaced.
    • Vehicle battery is disconnected.
    • Transmitter buttons have been pushed 256 times out of range of receiver.
  2. To resynchronize transmitter to receiver, stand within 5 feet to vehicle. Simultaneously depress and hold LOCK and UNLOCK buttons on transmitter for 7 seconds. Door locks should cycle to confirm resynchronization.
