Locks and Security Tips: • A maximum of eight keys can be coded to your vehicle. • Only use SecuriLock™ keys. • You must have two previously programmed coded keys (keys that already operate your vehicle's engine) and the new unprogrammed key(s) readily accessible. • If no previously programmed coded keys are available, you must take your vehicle to your authorized dealer to have the spare key(s) programmed. 1. Insert a previously programmed coded key into the ignition. 2. Turn the ignition from the 1 (off) position to the 3 (on) position. Keep the ignition in the 3 (on) position for at least one second, but no more than 10 seconds. 3. Turn the ignition to the 1 (off) position, and remove the coded key from the ignition. 4. Within ten seconds of removing the previously programmed coded key, insert the other previously programmed coded key into the ignition. 5. Turn the ignition from the 1 (off) position to the 3 (on) position. Keep the ignition in the 3 (on) position for at least one second but not more than 10 seconds. 6. Turn the ignition to the 1 (off) position, and remove the second key from the ignition. 7. Within twenty seconds of removing the previously programmed coded key, insert the unprogrammed key (new/valet key) into the ignition. 8. Turn the ignition from the 1 (off) position to the 3 (on) position. Keep the ignition in the 3 (on) position for at least one second. 9. Your new unprogrammed key is now programmed. If the key has been successfully programmed it will start the vehicle's engine and the theft indicator light will illuminate for three seconds and then go out. If the key was not successfully programmed, it will not start your vehicle's engine and the theft indicator light will flash on and off rapidly. If failure repeats, bring your vehicle to your authorized dealer to have the new key(s) programmed. 94 2009 05+ Mustang (197) Owners Guide USA (fus)
