I just bought a new key fob because the car only had one when i bought the car. My GM dealer programmed my new fob and everything works but the remote start. my original fob remote start does work, does anyone have any ideas.

I believe only key fobs 1 and 2 start the car, look at the DIC and see if the fob is 1,2,3 or 4. If its 3 or 4 the reprogramming procedure is in the owners manual. I bet when they programmed your new fob they just added it because reprogramming takes about 30 minutes. I lost my fob 1 and had to replace it, reprogrammed the car and both fob 1 and 2 start car no problem.

To get the new FOB to auto start you will have to reprogram both FOBs as FOB 1 and 2. Long process.

If you new fob was not properly matched as #2, it won't recall preferences, either.
