I don't know...........Mine had keyless entry already in it from the factory, just came with no key fobs. So I bought some and programmed it in. That was easy, but I don't know what would be fully involved if this option did not originally come on the vehicle. You could call your dealer and give them the VIN and they will tell you if it came on it from the factory if you don't already know. Good luck with your other programming issues, I have no clue what your issue would be.
