Locks and Security Automatic disarming Switching the ignition to the on position with a coded key disarms the vehicle. • The theft indicator on the instrument panel will illuminate for three seconds and then go out. • If the theft indicator stays on for an extended period of time or flashes rapidly, contact your authorized dealer as soon as possible. Replacement keys If your keys are lost or stolen and you don't have an extra coded key, you will need to have your vehicle towed to an authorized dealer. The key codes need to be erased from your vehicle and new coded keys will need to be programmed. Replacing coded keys can be very costly. Store an extra programmed key away from the vehicle in a safe place to help prevent any inconveniences. Please visit an authorized dealer to purchase additional spare or replacement keys. 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 authorized dealer to have the spare coded key(s) programmed. Please read and understand the entire procedure before you begin. 1. Insert the first previously 3 programmed coded key into the ignition and turn the ignition from 1 2 (off) to the 3 (on) position (maintain ignition in 3 (on) for at 4 least one second). 2. Turn ignition to 1 (off) and remove the first coded key from 1 the ignition. 85 2009 Grand Marquis (grn) Owners Guide (own2002), 2nd Printing USA (fus)
