This and other how-to articles are provided for informational

responsible for any damage that may occur as a result of performing procedures
outlined in any article. Please be sure to read and understand the entire
article before doing this.
These instructions will save you a lot of money. The dealer wants at least $50
just to do this simple procedure.....
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:

than those listed above. I cannot confirm that these procedures work for every
year and model listed. See your dealer if to confirm this.
On-Board Programming Method "B"
for Ford keys (1996 -early 1998 Ford, Lincoln, Mercury)
If you want to initiate a new master key....
1. Insert new key into ignition cylinder and turn it to the ON
(RUN) position. The security light on the dash will flash for fifteen minutes.
2. When the security light stops flashing, you have FIVE
minutes to start the next step. Turn the ignition cylinder OFF and then back
to the ON (RUN) position. The security light on the dash will flash for
fifteen more minutes.
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.
4. After the security light stops flashing the third time, the
new key has been programmed into the vehicles computer and will operate the
car. It has replaced ALL the previous electronic key codes and is the ONLY key
programmed into the vehicles computer.
If you want to add a key....
1. Insert an existing key into the ignition cylinder.
2. Turn the ignition cylinder to ON (RUN) and back to OFF.
3. Remove the existing key and, within 15 seconds, insert the
new key and turn it to ON (RUN).
4. The security light will light up for two seconds to
indicate success in programming the key into the vehicle.
5. Don't attempt to start the vehicle with any key for at
least 1 minute.
On-Board Programming Method "C"
for Ford keys (Later 1998-newer Ford, Lincoln, Mercury)
If you want to initiate a new master key....
1. This requires that the vehicle be connected to special dealer equipment.
There are two ten minute delays involved while this device erases all existing
key programming and sets up the vehicle computer to accept new key codes.
Two new keys should be ready because the system requires a minimum of two keys
in the program. After the first two keys are programmed, additional keys can be
entered individually by following the instructions for adding duplicate keys
(below).
If you want to add a key....
**You must have two original keys to perform this procedure. If you only have
one key, you WILL have to take it to the dealer to get it programmed**
1. Insert and existing (working) key into the ignition
cylinder.
2. Turn the ignition cylinder ON (RUN) and back to OFF.
Ignition should stay on for at least ONE SECOND.
3. Remove the existing key and, within TEN
seconds, insert a second working key and turn it to ON (RUN) and the
back OFF. Ignition must be in ON for at least ONE second, but no more
than TEN seconds. Remove the key.
4. Insert the new key before TWENTY seconds
have elapsed and turn it to ON (RUN). Leave it the ON position for at least
ONE
second and turn back to OFF.
5. The security light will light up for THREE
seconds to indicate that the new key has been successfully
programmed.
6. To program additional keys, repeat steps 1 through 5
As a precautionary measure for all of the above procedures, you should wait
at least one minute after you have performed this until you start your vehicle.
