KEY PROGRAMMING - ENABLE/DISABLE SPARE KEY PROGRAMMING 

Special Tool(s) 

ignition switch assembly has been replaced, and it is desired to erase key(s) 
from the passive anti-theft system (PATS) memory.

NOTE:

This procedure will erase all programmed ignition keys from the vehicle 
memory and the vehicle will not start until two keys have been reprogrammed 
to the vehicle.

NOTE:

Two PATS encoded keys with the correct mechanical cut must be available to 
perform this procedure. One or both of them may be the customer's original 
keys.

NOTE:

If additional keys are to be programmed, refer to KEY PROGRAMMING - 
PROGRAM A KEY USING TWO PROGRAMMED KEYS . If the remaining keys are 
with the customer and are not available with the vehicle, then instruct the 
customer to refer to the Owners Guide under the "Programming Spare 
[SecuriLock(R) (North America), Safeguard(R) (U.K.) or PATS for all other 
markets] Keys Procedure" for instructions on programming the remaining keys.

1. Insert a programmed ignition key into the ignition lock cylinder and turn the ignition switch to RUN.  

2. Enter diagnostic tool. Follow the SECURITY ACCESS - Procedure to obtain security access.

setting:  

From diagnostic tool menu, select SPARE KEY PROGRAMMING SWITCH selection to the desired setting: 

< ENABLE > Spare key programming procedure is accessible. 

< DISABLE > Spare key programming procedure is not accessible.

NOTE:

The spare key programming switch is a diagnostic tool programmable switch 
that provides the capability to enable/disable the spare key programming 
procedure. This procedure is in the Owners Guide spare key programming 
procedure or under Key Programming-Program a Key Using Two Programmed 
Keys. This programmable switch is provided as a convenience for rental 
company fleets or other fleet purchasers who may not want the spare key 
programming procedure available to the vehicle driver.

NOTE:

The spare key programming switch state can be viewed by instrument cluster 
PID SPARE_KY.

NOTE:

The default setting on delivery of all new vehicles is < ENABLE >.

1. Turn the ignition switch from the OFF position to the RUN position using the new, unprogrammed 

ignition key.  

2. Enter diagnostic tool using the Ford Service Function (FSF) card and enter the appropriate instrument 

cluster. Follow Security Access to obtain security access. Refer to SECURITY ACCESS-
PROCEDURE .  

3. From the diagnostic tool menu Select: IGNITION KEY CODE PROGRAM.  

NOTE:

This procedure is used when a customer needs to have an additional key 
programmed into the vehicle without erasing stored key codes, but does not 
have two programmed keys available. This procedure is also useful when 
attempting to determine if an ignition key is defective, as a new key can be 
installed without erasing keys or without having two programmed keys 
available.

NOTE:

Before programming, the new key must have the correct mechanical cut for the 
ignition lock.

NOTE:

If eight keys are already programmed, this procedure will not allow any further 
ignition keys to be programmed without erasing all stored key codes first. The 
number of keys programmed into the system can be determined using the PID 
NUMKEYS.

SECURITY ACCESS - PROCEDURE 

Special Tool(s)

Courtesy of FORD MOTOR CO. 

1. From diagnostic tool: Using the Ford Service Function (FSF) card, select the appropriate instrument 

cluster. Enter SECURITY ACCESS PROCEDURE. This procedure will take 10 minutes to perform, 
during which the ignition switch must be in RUN and the diagnostic tool must be connected to the 
vehicle.  

2. After the 10-minute security access procedure has been completed, a new menu will be displayed with 

command options. Select only those functions required before exiting out of this menu. Once exited out 
of this menu, the security access procedure must be performed again to perform additional commands. 

NOTE:

The security access procedure is utilized to obtain passive anti-theft system 
(PATS) security access. PATS security access must be granted to erase ignition 
keys, enable/disable the spare key programming switch or perform parameter 
resets for the instrument cluster. The security access procedure invokes an 
inherent 10 minute time delay prior to granting security access during which 
diagnostic tool must remain connected to the vehicle. Once security access has 
been granted, a security access command menu is displayed that offers various 
command options (refer to PATS Configuration Command Index).

NOTE:

Select only the commands required by the appropriate pinpoint test.
