GM made the factory keyless entry remote with FCC ID L2C0005T in a few button conifgurations but they are all compatible with each other. Your old remote will either say part number 12223130-50 or 16263074-99 on the back above the FCC ID. We test each remote before we send it to you to make sure it is sending the right signals to work with systems that use L2C0005T remotes. All vehicles that use L2C0005T remotes are not onboard programmable. This means that special equipment needs to be plugged into the vehicle to make the car learn new remotes. Local automotive locksmiths are best suited to perform programming for you. Note: Original remotes have a 1 or 2 on the back denoting seat memory. However, it is meaningless as there is nothing different about the electronics in regard to seat memory. The order the remotes are programmed into the car determines which will act as #1 or #2. It is NOT important to order a "pair" of 1 and 2 for it to work properly.
