Didn't know they had such a fancy name for them. I knew soldering is the best way, just wanted someone to tell me to take the easy route, no luck.

Looks like I can get the Viper 5301 for about $230 and another $40 for the bypass. It beats the heck out of the 6 to7 hundred I was getting quoted from the shops to have it installed.

The "chip" is actually a radio transponder. You may be thinking of the older GM keys. I believe they had resistors in them. They had contacts on each side and the ignition switch could read the resistance.

Basic transponder function:
PATS module energizes the transponder key through the transceiver halo. (run or start position)
Transponder key broadcasts its key code to the PATS module transceiver.
Transceiver sends a coded message to the PATS module
PATS module transmits a signal to the PCM to enable or disable start (fuel pump, starter, etc)

That is what I have read on other forums. .

Its not looking good for your bypass efforts of the PATS system. Your model is even more advanced. PATS II and is not a resistor.

PATS is Ford Motor Company's passive anti theft system. In 1996 it started showing up on select models of Ford and Lincoln Mercury vehicles. The keys for these vehicles have a tiny radio frequency transponder imbedded in the plastic Head.
When you attempt to start the vehicle, the onboard computer sends out a RF signal that is picked up by the transponder in the key. The transponder then returns a unique RF signal to the vehicle's computer, giving it the ok for the vehicle to start and continue to run. This all happens in less than a second, and is completely transparent to the vehicle operator. It is a very effective system that does its job without the vehicle owner having to think about it, or modify his / her usual routine.

So it may be best for you to have another key programed, then saw off the portion that slides into the ignition. This way the theif that tries to use it will soon realize they are in for more work and possibly abort.

Thats about the best I can come up with. It might be a lot less expensive, and you could avoid having to butch up additional wires. Either way, you are basiclly taking the PATS system off-line.

If they want your truck bad enough, they are going to steal it with a wrecker. So I would go with the least intrusive method.

I'm a slow typer, or most likely a slow thinker, was typing my last post while you already posted.

I was wondering how you would be able to just pry out the chip and put it in you steering colum to work. I had always heard that it was a resistor in the key. I had even read it on other forums and no one chimed in to tell the person they where incorrect.

I think this is all I should need extra. http://www.amazon.com/dp/B0011EPVGC/...SIN=B0011EPVGC

It's forty bucks after shipping is added in, but another key if fifty.

Yes. It looks like that one should work. You may also want to look at the PKFM. It has a D2D(digital interface) connection which can interface with Remote Starts with D2D ports.
