I am in South Korea. I support the Army here. I have a Ford Excursion 2000 V10 and I lost my key and key less entry some months back. I ordered and received a new Ford replacement with the chip (from STRATTEC) and I also ordered and received a three button and four button key less entry( I have multiple now-all new). I found a Korean locksmith who cut a the key for me (it does turn from off to on easily) and he and I programmed it (turn 8 times, door lock etc) I also then programmed the key less entry (doors will lock and unlock, double lock will sound horn). The problem is it wont start and it looks like the alarm or pats will not disable either with the key or with the key less entry. I remember when I had my old key and remote it would always chirp when I locked it and double chirp when I unlocked it. I does not that do that anymore and I don't know what to to do. Please some one help..

 

Welcome to the site..

It takes 2 programmed/working PATS keys available to program additional keys when programming them from the truck. It’s a security anti-theft design to keep the keys from being copied illegally. Ford or a capable locksmith will need to program the new keys. Without a programmed key available, all the key memory will have to be erased, and then 2 new keys programmed with the scan tool. If 1 programmed key were available, another could be programmed in.
Best to program 2+ otherwise your in the same boat if the single key is lost again..

If there’s no programmers available, it should be possible to program them yourself with a free program like Forscan, a Windows based laptop, and an elm327 adapter (switchable HS-CAN/MS CAN) that communicates between the trucks diagnostic connector to USB comm with the laptop. The adapters are inexpensive at approx 20.00 (eBay etc) so basically the software, laptop, and adapter gets you a very capable diagnostic tool, code reader with only a small investment..
