Locks and Security The theft indicator will flash every two seconds when the vehicle is armed. Automatic disarming The vehicle is disarmed immediately after the vehicle is unlocked using the remote keyless transmitter, the keyless entry system keypad (if equipped) or the door lock cylinder (on vehicles equipped with the perimeter alarm system). • The theft indicator will illuminate for three seconds and then go out. • If the theft indicator stays on for an extended period of time or flashes rapidly, have the system serviced by your dealer. 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 a dealership. 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 You can program your own coded keys to your vehicle. 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 two previously programmed coded keys are not available, you must take your vehicle to your dealer to have the spare key(s) programmed. 83 2005 Montego (mgo) Owners Guide (post-2002-fmt) USA_English (fus)
