No, because it depends on which Body Control Module is installed in the car:
Type 2 BCM: Power Locks
Type 3 BCM: Power Locks & Keyless Entry (RPO AUO)
Type 4 BCM: Power Locks, Keyless Entry & Factory Alarm (RPO UA6)
Your best bet would be to call the parts dept of your GM dealer, give them the year, make, model & last 8 digits of the VIN, and they can give you the part # for the key fob. Then you can buy one or two off Ebay, and program it/them...
