Question about 2004 Ford Explorer
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.

Normally, you would insert the key in
the drivers door, turn left, then right
to disarm and reset it. If yours is malfunctioning,
you would either need to contact Ford to reset it, or
you can disable it for good by doing the following:
The FACTORY ALARM DISARM WIRE IS green/purple |-|,
Located in the drivers door harness or the
drivers side kick panel.
Once Located, splice into either wire with
a simular guage wire, and put it to
a solid chassis ground. This terminates
the alarm functions entirely.
However, at this point, this car would be exceedingly
easy to steel, so I suggest you get an aftermarket
alarm system to protect it from here on in.

Try disconnecting your battery cables then wait about 10 minutes. The computer should reset itself. Reconnect the wires to the battery. It is normal for the theft light to blink about every 5 seconds when the ignition key is out or in the off position. This means the system is armed and working properly. Hope this helps. God bless!

With the doors shut, insert the key into the drivers door lock. Lock and unlock the door 5 times. This should reset the system. If that doesn't work you should contact a qualified repair shop.

Almost always the key is not at fault. I know for sure heat changes the resistance of the key but it does not happen as a usual thing you would have to apply physical heat. Contact me at firstname.lastname@example.org
