Yes. Most are set up to interrupt the power to the fuel pump or ignition.

If the theft light is flashing with the proper key in the ignition then either the chip in the key is bad or the transceiver on the ignition cylinder is faulty. The PATS system is built into the PCM.

Yes I agree it's the 'smart key'. Normally when you buy an explorer new, you will get 3 keys. 1 of the keys is a valet key.
If you were to copy another key that has a smart chip (transponder) in it, the new key won't work until you 'program' the third (new) key. To program it you need the original 2 keys that work.
The only other thing could be that there was a remote start in the vehicle and there could be something wrong with the module that bypasses the transponder. If there is a remote start in the vehicle you might be lucky to some extent if it still works.
If you move the shifter hard and it worked before, like you said, there could also be damage to the wires that goto the key cylinder, the reciever for the transponder in the key. Try having someone hold the key in start and use the tilt wheel, that too will tell you theres damaged wires if it starts.
Unfortunately you probably will have to bring the vehicle to a ford dealer to get additional keys programmed or the damaged part replaced.
It shouldn't cost too, too much. Just be glad you don't have a Saab, replacement key's are $145 Ea!
If your inclined, you can dissassemble the plastic shroud around the steering column and look for damaged wires coming from the black ring around the key down the the connector under the dash.
