Programming Procedures: 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. Receiver will not respond to a signal it has been sent previously preventing recording and playback of transmitter signal. Resynchronization will be necessary if and of the following occur:
    • Transmitter battery is very weak.
    • Transmitter battery is changed.
    • Vehicle battery is very weak.
    • Vehicle battery is replaced.
    • Vehicle battery is disconnected.

To resynchronize transmitter to receiver, 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.
