PATS system won't start with only one key

[espritv8]

Hi,

On of my factory keys stopped working. It's clearly the pats system preventing the engine from starting. The 2 other keys are working.

Is there an easy fix for this like a resetting procedure or it's a mandatory trip to the dealer?

The truck is an 2010 Navigator.

Thanks

the chip may be dead or malfunctioned in the key...take to ford or buy new key

How much does that cost?

Keys do quit working from time to time. If you still have 2 different (not cloned) working keys you should simply need to purchase a new key and have anyone capable of cutting it do so, doesn't have to be a dealer. You can add a new key through through a learn procedure w the two other keys.

OK that was my first tough. Funny thing is that it will start from time to time.

Get the new key now while you can still program it yourself easily. Once you're down to 1 key, it gets more complicated/costly.

You can add a key(s) with FORScan with just one key, if worst comes to worst.

Thanks for the advice. I'll try reprograming the defective key if it makes any difference.

Well the key is working on and off...So no need to program it. It's kind of weird.
