Have had trouble with remotes and keyless entry not working on our 2002 Ford Explorer. We decided to replace the "RAP" module after attempting many other things. However, the dealer calls it a Central Security Module. The directions on this forum are pretty explicit. However, the directions with the part claim to need to have the "Dealer" program the unit from the old unit before we install it. Need help. Can't find any other help anywhere. The dealer is NO help. Anyone have any suggestions?
