Transmitter Synchronization
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2000 GMC Yukon XL, 2000 GMC Yukon, 2000 GMC Sierra, 2000 Chevrolet Tahoe, and 2000 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.
Resynchronization may be necessary due to security methods used by Remote Keyless Entry (RKE) system. Transmitters do not send the same signal twice. Receiver control module 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 has been discharged for an extended period of time.
To resynchronize transmitter to receiver control module, 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.
