Transmitter Synchronization
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 1999 GMC Yukon, 1999 GMC Suburban, 1999 GMC Pickup, 1999 Chevrolet Tahoe, and 1999 Chevrolet Suburban. However, it is still accessible from the selected car via links, so may be relevant.
- Transmitter synchronization may be necessary due to the security method used by the RKE system. The transmitter does not send the same signal twice to the receiver.
- The receiver will not respond to a signal which has been previously sent. This prevents anyone from recording and playing back the signal from the transmitter.
- Resynchronization will be necessary if any of the following occur:
- You change the transmitter battery.
- You disconnect the vehicle battery.
- You push the transmitter button 256 times out of the range of the receiver.
- In order to synchronize the transmitter with the receiver, perform the following:
- Stand close to the vehicle.
- Simultaneously press and hold the LOCK and UNLOCK buttons on the transmitter for seven seconds.
