GENERAL PROCEDURES
Key Programming —
Program a Key Using Two
Programmed Keys
NOTE: This procedure only works if two or more programmed ignition keys are available and it is
desired to program additional key(s). If two keys are not available, follow the procedure in Key Programming — Erase All Key Codes and Program Two Keys .
NOTE: PID SPARE_KY must be enabled for this procedure to operate. If this Parameter Identification
(PID) Index is not enabled, follow the security access procedure and select Spare Key Programming
Switch: Enabled.
NOTE: If the programming procedure is successful, the new key(s) will start the vehicle and the
THEFT INDICATOR will illuminate for approximately three seconds.
NOTE: If the programming procedure is not successful, the new key(s) will not start the vehicle and the
THEFT INDICATOR will flash. If the programming procedure was not successful, repeat the key
programming procedure from Step 1. If the failure repeats, check Circuit 729 (RD/WH) (hot at all times)
in instrument cluster for proper battery voltage. Repair the circuit if voltage is not present. For
additional information, refer to Diagnosis and Testing to review diagnostic trouble codes (DTCs) and
perform pinpoint tests as required.
NOTE: A maximum of eight ignition keys can be programmed to a passive anti- theft system (PATS)
equipped vehicle. Use PID NUMKEYS to determine how many keys are programmed to the vehicle.
NOTE: If the steps are not performed as outlined, the programming procedure will end.
NOTE: Ignition keys must have correct mechanical key cut for the vehicle and must be a PATS
encoded key.
1. Insert the first programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the ignition switch in RUN for one second).
2. Turn the ignition switch to OFF and remove the first key from the ignition lock cylinder.
3. Within five seconds of turning the ignition switch to OFF, insert the second programmed ignition key into the ignition lock cylinder and turn the ignition switch from OFF to RUN (maintain the
ignition switch in RUN for one second).
4. Turn the ignition switch to OFF and remove the second key from the ignition lock cylinder.
5. Within 10 seconds of turning the ignition lock cylinder to OFF, insert the unprogrammed ignition key (new key) into the ignition lock cylinder and turn the ignition switch from OFF to RUN

GENERAL PROCEDURES
Key Programming —
Enable/Disable Spare Key
Programming
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 in this section 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.
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. For additional information, refer to Security Access — Procedure to obtain security access.
3. NOTE: The default setting on delivery of all new vehicles is <ENABLE>.
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.

GENERAL PROCEDURES
Key Programming —
Additional Key With One Programmed
Key
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.
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. For additional information,
refer to Security Access — Procedure .
3. From the diagnostic tool menu Select: IGNITION KEY CODE PROGRAM.
4. Turn the ignition switch to the OFF position and disconnect diagnostic tool.
5. Attempt to start the engine with the new ignition key. The vehicle engine should start and run normally.

GENERAL PROCEDURES
Security Access —
Procedure
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.
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.

Inspection and Verification
1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the diagnostic tool does not communicate with the vehicle, refer to the diagnostic tool manual.
5. Carry out the DATA LINK DIAGNOSTIC TEST. If the diagnostic tool responds with: zCKT 914, CKT 915 or CKT70 - ALL ECUS NO RESP/NOT EQUIP, refer to Section 418 -
00 .
z NO RESP/NOT EQUIP for the generic electronic module (GEM), go to Pinpoint Test A.
z NO RESP/NOT EQUIP for the instrument cluster module (ICM), refer to Section 413 - 01 .
z System passed, retrieve and record the continuous diagnostic trouble codes (DTCs),
erase the continuous DTCs and carry out self- test diagnostics for the GEM or ICM.
6. If the GEM or ICM DTCs retrieved are related to the concern, go to the GEM or ICM Diagnostic Trouble Code (DTC) Index.
7. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.
