WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Do not operate or program the transmitters 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 method 1-3. Up to four transmitters may be programmed to the passenger door module (PDM). Each programmed transmitter is given a position #1-#4 in the PDM memory.
