Ford Experts? Securilock reset?

[The GECCO]

So, I was doing some work on the HPR Pace Car (2005 Mustang) that required disconnecting the battery. After reconnecting, everything is FUBAR! LoL

The Anti-theft light flashes rapidly, and the engine won't turn over. The dash also displays "Engine Failsafe Mode"?

Anyone familiar with a method to reset this, other than taking it to the dealer?

Glenn...i'm sure if you jump on a mustang forum...there will be an easy way to fix...you'll just have to do some searching. Had a similar issue w/ my accord...Thank God Fpr the interwebs!!!

^^That.

I've never had that issue on my '99 Mustang, but it's older and less sophisticated
