SOURCE: anti theft device for 97 ford expedition
I have 2007 expedition XLT and the interior light blinking all the time what the solution ?
SOURCE: anti theft system
The chip is in the key. Either the key has lost it's program or the transceiver is not recognising the key. Try another key if you have one.

The old key may have an induction chip in to deactivate the anti theft system. Does it have a red insert (chip) in the key handle? Get the old key and place it as close to the ignition barrel as possible. Seen this done on a number of occasions to save paying for a key reprogram.
Testimonial: "the key had broke off in the hatch of the vehicle. we pulled it out but when they changed out the ignition they broke the reader for the chip on the key so. we took the steering collumn and the ignition from an old 1999 ford exlorer which is the same. But the anti theft is still on"
SOURCE: How do I disable the anti-theft system?
First hooking a battery up backwards can damage computers and the alternator. The battery for your car is opposite of every other battery on the market. Some thing to think about. So with that. Start the car, remove the positive post from the battery. If the car dies, replace the alternator. The security system will not drain a battery every two or three days with the car being driven two or three times a day. Especially a new battery.
