Check to make sure the coded key is an approved Ford coded key. If your keys are lost or stolen you will need to do the following: • Use your spare key to start the vehicle. or • Have your vehicle towed to a dealership or a locksmith. The key codes will need to be erased from your vehicle and new key codes will need to be re-coded. Replacing coded keys can be very costly and you may want to store an extra programmed key away from the vehicle in a safe place to prevent an unforeseen inconvenience. The correct coded key must be used for your vehicle. The use of the wrong type of coded key may lead to a "no start" condition. If an unprogrammed key is used in the ignition it will cause a "no start" condition. Programming spare keys A maximum of eight keys can be coded to your vehicle. Only SecuriLock keys can be used. To program a coded key yourself, you will need two previously programmed coded keys (keys that already operate your vehicle's engine) and the new unprogrammed key(s) readily accessible for timely implementation of each step in the procedure. If two previously programmed coded keys are not available, you must bring your vehicle to your dealership to have the spare coded key(s) programmed. Please read and understand the entire procedure before you begin. 1.
