Locks and Security 1. Insert the first previously programmed coded key into the ignition and turn the ignition from the 1 (off) position to the 3 (on) position (maintain ignition in the 3 (on) position for at least one second, but no more than 10 seconds). 2. Turn ignition from the 3 (on) position back to the 1 (off) position in order to remove the first coded key from the ignition. 3. After three seconds but within 10 seconds of removing the first coded key, insert the second previously programmed coded key into the ignition and turn the ignition from the 1 (off) position to the 3 (on) position (maintain ignition in the 3 (on) position for at least one second but no more than 10 seconds). 4. Turn the ignition from the 3 (on) position back to the 1 (off) position in order to remove the second coded key from the ignition. 5. After three seconds but within 10 seconds of removing the second coded key, insert the new unprogrammed key (new key/valet key) into the ignition and turn the ignition from the 1 (off) position to the 3 (on) position (maintain ignition in the 3 (on) position for at least one second, but no more than 10 seconds). This step will program your new key to a coded key. 6. To program additional new unprogrammed key(s), repeat Steps 1 through 5. If successful, the new coded key(s) will start the vehicle's engine. If not successful, the new coded key(s) will not start the vehicle's engine and you may repeat Steps 1 through 5. If failure repeats, bring your vehicle to your authorized dealer to have the new spare key(s) programmed. PERIMETER ALARM SYSTEM (IF EQUIPPED) The perimeter anti-theft system will warn you in the event of an unauthorized entry to your vehicle. If there is any potential perimeter anti-theft problem with your vehicle, ensure ALL remote entry transmitters are taken to the authorized dealer to aid in troubleshooting. 149 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
