KEY PROGRAMMING 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, refer to Key Programming Using Diagnostic Equipment. See: Antitheft and Alarm Systems > Programming and Relearning > Using Diagnostic Equipment - PID SPARE_KY must be enabled for this procedure to operate. If this PID is not enabled, follow the security access procedure. Refer to Anti-Theft Security Access and select SPARE KEY PROGRAMMING SWITCH: ENABLED. - If the programming procedure is successful, the new key(s) will start the vehicle and the THEFT indicator will illuminate for approximately three seconds. - 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, refer to Diagnosis and Testing to review the DTCs and carry out the pinpoint tests as necessary. - A maximum of eight ignition keys can be programmed to a passive anti-theft system (PATS) equipped vehicle. If more are needed, refer to Key Programming Switch State Control. See: Antitheft and Alarm Systems > Programming and Relearning > Switch State Control - If the steps are not carried out as described, the programming procedure will end. - Ignition keys must have correct mechanical key cut for the vehicle and must be a PATS encoded key. - If the vehicle is in unlimited key mode, this spare programming procedure still functions. Any two keys that can start the vehicle may be used to program in an additional unlimited key. 1. Insert the first programmed ignition key into the ignition and turn the ignition from OFF to ON (maintain the ignition in ON for one second). 2. Turn the ignition OFF and remove the first key from the ignition lock cylinder. 3. Within 10 seconds of turning the ignition OFF, insert the second programmed ignition key into the ignition and turn the ignition from OFF to ON (maintain the ignition in ON for one second). 4. Turn the ignition OFF and remove the second key from the ignition lock cylinder. 5. Within 20 seconds of turning the ignition to OFF, insert the unprogrammed ignition key (new key) into the ignition and turn the ignition from OFF to START (attempt to start the vehicle). 6. If it is desired to program additional key(s), repeat the key programming procedure from the beginning.

If not , unfortunately you will need ford scanner or equivalent ,now days a lot of lock smith have these scanner and will come to you
