To start, Just bought an 07 SS. Couldn't believe the condition it was in 48k mi and immaculate inside with a fairly new Kenwood deck installed(which I will be removing for a new nav unit down the road)
So I read the article onn how to program my rke fobs...
Then went ahead and bought 2 brand new fobs off ebay. Part number GM15008008(which is the same part number that was on the back of the working fob that came with the truck).
The single fob that I got from the dealer when I bought the truck works fine. The truck goes into program mode, programs the first(original remote that the car came with) and then I get nothing from either of the new fobs. I checked the batteries in each and even swapped the battery from the working fob to one of the new ones and still nothing happens. I do not have the memory seat function to the best of my knowledge( I have cloth seats and no steering wheel controls).

to eliminate the possibilities put your TB in programming mode and attempt to reprogram your original FOB, then attempt to program the new FOB's. If the original reprograms and the new don't then there's a problem with the new ones.
! My old FOB looks brand new now but still functions like sh**! 

! While you're at it how about you fill out your profile information about your vehicle!
