IMPORTANT: Different keyless entry systems are used on General Motors vehicles. The parts are not interchangeable even though the parts may appear to be similar. Observe the back of the transmitter in order to properly identify the system. On 2000 SIT pickups and utilities, use a transmitter identified with GM/UTA preceding the part number.
IMPORTANT: All extra transmitters must be programmed at this time. When a new transmitter is programmed, the old transmitters will be deactivated.
