The keyless entry/alarm "brain box" is located kinna high in the dash. Best bet is to remove the drivers side kick panel but I think you need to remove the scuff plate first (door thresh-hold piece). then pull the kick panel out of its clips. Once they are removed look up into the dash Kinna behind the interior light dimmer switch mounted to the firewall. You'll see a black box with many wires coming from it. I believe there is a green button there that I thought was a reset. Thats most likely what he's speaking of. I've never reprogrammed a remote but I'm sure someone on the forum knows how.
Hope this helps...carlymac
