I just recently purchased an 03 Duramax that has an AstroFlex Remote start system except the dealer did not have the key fobs. I looked under the dash and found these numbers. Model 2100, Part # 392-127-102-03, Serial #2100093043. There is also a Valet switch on this system.

Is there any way I can get replacement fobs for this? Is there something else I should look for. Any help would be greatly appreciated.

Thanks,

No need to worry about this FCCID#, just find the trans. part# I posted. Programming a new remote is simple.

Kar Tune Man -- I remember talking to the installer that put my wife's AstroStart in her van a couple years ago about getting a second key fob for it and even mentioned I had the same type of key fob for my Grand Prix's remote starter. I thought he has told me that it was possible to program both my wife's van and my car into one remote. Is this possible? I can't find instructions on how to do it anywhere... Thanks in advance for any help or advice you can give!

Your trasmitters ARE 2 car programable. The first car is controlled by using the transmitters normally. The second car requires a quick push of the button BEFORE holding them to get action.

Example: to strt the second car you would push the start button, let up, then push and hold.

You program the TX in the same way. Have all of the transmitters you own, and both cars ready before you start to learn them... can get confusing.
