The wife and I just purchased a 2007 Impala a few weeks ago with 23,000 miles on it, was a certified pre-owned from the local Chevy dealer here. Anyhow, we love the car but we're having some difficulty with our remote key fobs. Seems like only one fob can be programmed at any one time. If I try to program mine, hers comes unprogrammed. I know there is a 8 remote max on the Impalas per the owners manual, but my question is this... How can you clear out any past remotes programmed so we can get our two remotes to program and stay programmed? I'm planning on taking it back to the dealer in the morning, but if it's something I can do here at home I'd just as soon do that. Thanks for your help in advance!
