Sadly this isn't bull. Most newer keys have a passive anti theft system (PATS) where there is a chip inside the key body that allows your car to crank when the key is turned. There is a procedure to program spare keys yourself for only the cost of the key blank and cut, but you HAVE to have 2 keys already programmed to the car to do it. If you only have 1 key left, you can't program it yourself and have to go to ford to get it done for you. $110 is unfortunately what they charge. Maybe there is a DIY workaround, but I haven't heard of one.

If you get your key replaced, look up the PATS programming procedure and make yourself some extras. The blanks are pretty cheap on ebay.

Good luck
