FCC ID KOBGT04A
Choosing the Correct Part number for your car
Even though all of these are in the same KOBGT04A family, not all could be compatible replacements for your vehicle. If you have an existing remote, compare the GM part number on the back of it to the numbers below. By choosing the same one, you can be sure it will work.
All vehicles that use these remotes are not onboard programmable. That means that your vehicle doesn't have a manual way for you to do the programming yourself. Special equipment needs to be used on the car to do the programming. A local automotive locksmith is usually the best professional to perform this service for you. Any GM dealership can also perform this service.
All remotes in the KOBGT04A use the CR2032 battery. To change the battery, look at the bottom of your remote along the seam off to the side of the keyring hole there is a small space to insert a small flat-head screwdriver. Do so, then twist. The remote pops open and you can see the battery on the circuit board. Be careful when removing the battery as a known issue in the design of this circuit board is that the soldering for the battery contact often comes free when removing a battery.
These 12 GM part numbers boil down to 4 groups, A, B, C and D. As long as you choose one within the same group as what your vehicle calls for then it will be able to be accepted by the vehicle during remote programming.
Group A: 15252034 , 22733524
Group B: 15114374 , 15114375 , 15114376 , 15788020 , 15788021 , 15777636
Group C: 15100811 , 15100812 , 15100813
Group D: 22733523
