My 2004 Explorer will not turn over with the key but i can hook up a remote start switch and get it to turn over. It will not start with the remote start switch even though i have fuel and spark. The anti-theft light on the dash flashes rapidly when the keyis turned to teh start position. Could it be with the anti-theft system?
I had almost same problem with my Explorer XLT 2002, the anti-teft was activated when my battery died, I tried with the Jump starter and connect it directly to another car with cables, but didn't work!!!!! only made click.click.clik... and never started. so I removed the battery and took it to AutoZone to check it, and it was a bad battery perhaps, so once I installed the new battery and open the driver's door with key (be sure all is closed before that so use the driver's lock switch). if you have pad on the sash may work too. the truck started!!! :)
Its a good possibility that the Anti-theft is interferring with the circuit. If you have an extra ignition key, use that in case the password chip in your regular FOB has detriorated.
There is a brake sensor which is on the upper brake pedal. It interlocks with the starter to prevent starting without having your foot on the brake pedal. Check your brake lights for operation. If the brake lights stay dark with your foot on the pedal, the switch is broke or knocked out of position. A common problem.
Next, there are small wires for the starter solenoid. You can use a test light on one removed wire and ground the test light to the vehicle, the other end in the small wire. Turn the keyswitch to start, with brake pedal pressed and see if it lights up. If it does light up, the starter solenoid may be bad.
Battery level. Ford Anti-theft and some say Battery-saver, can cause both starting and charging problems. A fully charged battery can be at 13.2V- 13.6V. When Ford systems detect low voltage it can activate the Anti-theft, battery-saver, and even disconnect the charging system to allow the battery to completely drain. In some cases the Anti-theft drops starter voltage to around 7V so the starter will not spin. Have the battery tested.
I know of 2004 trucks that were jump started and showed charging, then after 5-10 minutes they lost the charging system. Some people lost the charging system at 70MPH and drove until they stalled. All because of the automatic features built into the trucks. A new battery fixed the problem. Your problem could stem from this.

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.

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.

Two tips:
* If your anti-theft system is sounding (horn honking/lights flashing)you press the panic button on your key fob to shut it off.
* If your anti-theft system is armed (but not triggered) it is disarmed when you unlock the door(s) using your unlock button on your keyfob, the key pad on the driver's door, or your key.
Hope help with this. Good luck (remember rated this).

Try re-setting the computer...Disconnect the negative terminal of the battery and leave off for 5-10 minutes. This will allow the computer to reset. The charger may have interupted the signal or something.

Yes you have a problem with the theft system. Have you tried a different key? It has a transponder system.
