How to program a replacement PATS key....
Ford Trucks for Ford Truck Enthusiasts
If you don't have any keys programmed you will need a locksmith To come to the vehicle to program 2 keys. This is assuming that keys you have are cut and will turn.
The 15 min thing has never worked for me.
If you want to email me, then I will give you my phone number. At least I can give you an explanation of how it works.
To start off, I'll explain a bit about what a PATS key is, what it does, and why this might concern you.
PATS is an acronym that stands for Passive Anti-Theft System (Ford also calls this SecuriLock). It is also called a transponder key. It is a security feature found on most (if not all) new Ford products, and what it does is disable your vehicle's starter unless your specially programmed key is used to start the vehicle. There is a computer chip inside of the key, and without that you will NOT be able to start the vehicle -- even if you have a regular (non-PATS) key with the correct cuts, it will not work.
For convenience, I'm also including a list of other vehicles that these instructions apply:

3. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder to OFF and then back ON (RUN) position. The dash will flash for fifteen more minutes.

Remember, the fob key has two functions. It is chipped to the engine to start the vehicle. Additionally, you have to program the remote lock/unlock functions in your new fob key.
Otherwise, if you simply marry a new key, using two original keys, this new fob key will only start the engine. Until you also program it as a remote locking/unlocking key, you won't be able to lock/unlock. So there are actually two programming steps- one for marrying the new fob key to your ignition, and one for activating the remote lock/unlock feature.
So, first , follow the instructions to marry the new fob key spare (third, fourth, etc) to your ignition system, using two original Ford keys. After programming the new fob key to start the engine, follow the instructions in this thread for activating the lock/unlock remote feature in your new key. Otherwise , you now have only a new, simple ignition key fob, and no working unlock/lock remote features.
If you're still having problems, locate a very good locksmith. They can program new fob keys,and maje vaket

If you're still having problems, locate a very good locksmith. They can program new fob keys,and make a spare valet key if you're needing a simple hide-a-key entry ignition key with a chip built in. A valet key does not replace your original fob key, just acts as a rudimentary backup in case you are locked out or needing to lend your car.
Bottom Line: Keep good spare fob keys for daily use , and put your two original fobs away. Losing either of these originals costs do ray me at the dealership $$$
