Most new GM vehicles, additional fobs can be programmed in the car itself. I have a C7 Corvette and used this procedure to program my additional fob.
Fob Programming
yes GM is easy. on my denali it uses chip keys and as long as you have two working keys, additional keys are around $15 each and they are easy to program with good instructions in the manual. Same with fobs. But the fob's aren't inexpensive. at least the chip keys are cheap and small. With the chip keys I have an extra key on with each of my trailer key rings, along with extra keys in the trailer.
And on my older MB the chip keys or fobs came preprogrammed. Give all the info to the dealer by 4pm and by 8am the next day pickup the key or fob and good to go. No programming needed.
On our Acura with keyless go, dealers and key shops can do a new fob, but they aren't inexpensive.
