Non-interchangeable Keyless Entry Remote Key Fobs with FCC ID KOBGT04A

One should be a little cautious when purchasing a replacement remote control for a GM car or truck that has an original remote with FCC ID KOBGT04A on the back. Not all remotes with FCC ID KOBGT04A are interchangeable. In particular, GM sedans used 4-button keyfobs with lock, unlock, trunk and panic icons that look identical except for the GM part number on the back of the case. But these transmitters are not interchangeable.

Keyless entry remotes with FCC ID KOBGT04A and GM part number 10305091 or 22733523 are equivalent to Remotes Unlimited part number 508-1508. Keyless remotes with FCC ID KOBGT04A and GM part number 15252034 are equivalent to Remotes Unlimited part number 717-1717.

GM sedans with keyless entry systems that used either of these parts require scan tool programming to add a new remote. So, your vehicle and all remotes you want to use with the vehicle will have to be taken to a dealership for programming.
