2003 Explorer Sport, remote start

Well the other day while installing a remote starter, 1w900fm-s, I somehow managed to confuse the computer on this gem of a vehicle, no keys work they all trip the anti theft light for the pats system. Anyone ever had anything similar happen, or know how to fix it. I already have it at a dealer being reset and scanned, but damn what a pain.

Nope. That's the only way. had a windstar that i did the same thing on and both keys would work intermittently. The thing i did wrong was when the theft light goes out when programming new key, I cranked it just a little, but didn't start it. So then all the keys were intermittently working and I went to the dealer, had them clear and reprogram all keys, and it worked fine. It happens. Good luck!My rifle is my friend...
