Thank you. I just checked the Owner's Manuel. This is a Lincoln Mark LT, 2006. The owner's manuel does refer to a passive anti-theft system as standard oy qn the vehicle which prevents the engine from starting if a key not compatible with the car's automatic push-button on key entry system is used. But this truck was not moved by the alleged burglar, just broken into.
My question is if the door lock was pushed in enough to get the door open, wouldn't that 1) set off the alarm, and 2) prevent the correct key from locking and unlocking this door? It doesn't make sense to me that this kind of forced entry wouldn't disable the automatic locking and unlocking system.....so how can she not notice for 4 days?
