I bought a used 99 Expedition and was given only one key and remote. I went to a dealer and bought a new key (they cut it) and remote. Dealer was busy and told me it would be several hours to program new key and remote.

Have stopped by several dealers and they all tell me I need to leave the vehicle for several hours until they can get to it. I know this takes them a minute or 2 to do.

Is this something I can do myself? If so where can I get detailed instructions.

Thanks
