My wife bought a 2006 Monte Carlo from a private party. The car has a factory remote start in it and someone has added a range extender kit made by Xpresskit. It's called Datastart. The remote we got was in pretty bad shape so I bought her a new remote for it but now I don't know how to program it. I install remote car starters for a living and I know the procedure is a fairly simple one but I can't remember what the steps are. If anyone out there can help me out, I know my wife would sure appreciate it.
