How to program PATS using FORScan v2.2.*

This article describes PATS programming procedure. The article is actual for version 2.2.11 (PATS programming is
implemented for Ford models approximately of 1997-2009 model year, depends on model and market, also some
Mazda, Lincoln and Mercury models). If PATS programming functions is not available in the list of service
functions, it means it is not implemented for this model. If the PATS programming function is available in the
Service chapter, it is implemented for this model and must work in full.
There are 2 types of secure access: coded and timed. Coded requires an incode generation by the outcode provided
by vehicle. Timed access requires that operator has wait for some period of time (usually 10-12 minutes) with
diagnostic tester connected. Some vehicles support only coded access, some only timed access, some support both.
FORScan supports all of these options. If both access types are available, FORScan asks user to select the
preferred one. Coded access can be done fast, but requires incode/outcode calculator. Timed access doesn't require
any code exchange, but requires signfificant timeframe (at least 10 mins). Module Initialization option (available
for some models) may require special Dual coded access. Detailed information about Module Initialization function
is available in this article:
So, what do you need in order to program PATS using FORScan:
1. Extended license (viewtopic.php?f=5&t=836)
2. At least one valid ignition key (master key) that is known by PATS, except the case when all keys are erased
from the PATS memory
3. For vehicles with coded access, access to outcode/incode key generator (we use free site
for this purpose, account has to be registered there)
Let's review a use case for the following scenario: a vehicle supports coded access. PATS knows 2 master keys, but
Let's review a use case for the following scenario: a vehicle supports coded access. PATS knows 2 master keys, but
the owner has only 1 of them. The owner wants to erase the lost key from the PATS memory and program new one
(for this purpose a blank key is purchased). There is no way to delete a single key, only all known keys can be
erased. So the user has to perform the operation in 2 steps: remove all keys known by PATS and program the old
key and the new key. Here we go:
- Run the procedure. We see that PATS knows 2 keys:

- Select the Ignition Keys Erase option. FORScan will read outcode from the vehicle and suggest you enter the

- login to the and go to Service->PATS login calculator, enter the outcode and generate the

- enter the incode in the FORScan field and click ok. If everything OK, FORScan will request confirmation on the
Erase operation. If confirmed, the operation is executed and user is returned back to the main menu. User should
see now zero keys known by PATS.
It is important to do not Exit from the menu, otherwise the security access will be lost, and user will have to obtain
the coded/timed access again.
- Now, user should program 2 keys. For this purpose the Ignition Key Programming option must be used. User will
be suggested to program the key:

- User should follow the instruction displayed by FORScan, so turn the ignition key to OFF, then back to ON and
click OK. FORScan will confirm the operation and ask to turn on/off again.

It is important to leave the programmed key in the ignition lock, because number of known keys is non-zero and
FORScan will look for a master key.
- program the second key in the same way, except that when FORScan asks to insert new key, the first key has to
be removed and the second key has to be inserted.
- When returned back to the main menu, user should see 2 known keys again. But this time these 2 keys are in
Note: some models for Australian and American markets have no stand-alone Ignition Key programming function.
The function is available in the PATS menu but PATS doesn't support it. So on these models it is not possible to add
a key to th PATS memory. The only way is to use Erase and Program keys function (added in FORScan v2.2.5).
This function erases all keys and switches PATS to a special learning mode. In this mode user can program 2 keys
one by one.
We also recommend to read this article to study Module Initialization procedure and use cases:
Experience shows that 90% of problems with using this function are caused by blank key problems
(not-original/china clone or from another model). Consdering this experiene, it must be counted that the Erase
function is potentially dangerous, because
engine will not start until you program at least 2 keys.
So it is
to check the blank keys (and correct work of the program with your specific
vehicle) before executing the Erase function. Just programm it as the 3rd key and if it has been programmed
successfully and engine runs using this key, you may execute the Erase function.
Here is a dedicated article about how to check the blank PATS key:

Good information!
I'm wandering if Forscan will perform this on my brother fiesta st150 2005 as he only has one key?
I'm slightly confused as it states programming blank keys,
Does this mean the original working key cannot be resused?
Also wondering if the key has to be blank, I.e is a second hand key programmable?
Many thanks
Good work!
