Ok, so this is the deal.My keyless entry has been screwin up for a while now.Its circuit board is now deceased.So i picked up 2 used key fobs for 5 bucks at a junk yard.They look identicle to mine, but are off of an impala (05 i think and they have the spot for the battery in a different place)First, will impala fobs work and second, how do you program one of these babys anyway???

Any advice would be greatly appriciated, tanx
