WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
Important: Do not operate or program the transmitter in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.
There are 3 methods for programming transmitters, which are listed below as methods 1-3. Up to 4 transmitters may be programmed to the passenger door module (PDM). Each programmed transmitter is given a position of #1-#4 in the PDM memory.
