Nope. Not without the original keys. The bypass unit communicates with the PCM over a network and unless you know that protocol and how to use it you can't override it.

It's Ford for you, I'm afraid. Your niece owes you I think?... ... I can see your dishes getting done, the house cleaned, yard mowed for a very long time, lol.

Ah, your brother owes you also. He obviously had no clue if he even attempted it. He probably applied voltage to a communications line and fried the drivers.

chryslers and gms program this way so try this and see if it works...

put that key in the ignition and turn it to the on position and let it sit for 15min. It should learn the frequency from the transponder thats atleast how it works on other cars i have worked on.

That's not a very secure system, Peter. That means if I have any key with a transponder and a non-transponder key I can turn on the vehicle with the non and just hold the other one there until it learns it, then start the vehicle. If I can jimmy the wires, I don't even need a key cut for the vehicle, just any transponder from the manufacturer.

I don't like that at all. Fortunately, that won't work with our system.

Plus, it appears his brother burned out the PATS unit.

Did the dealer tell you which part they intend to replace?

If is just the PATS transceiver or PATS module that is bad, you should be able get one fairly inexpensively from a junkyard (look for a 99~2000 V6 Ranger - parts from other years won't work with your PATS).

If you install a replacement PATS Module (above the glovebox forward of the PS airbag), you will have to pay a dealer to introduce the replacement PATS Module to your PCM and introduce your keys to the PATS module. That should be around $100 or so plus the part and the tow. Expensive but obviously way better than paying $1000.

If you replace the PATS transceiver (on the steering column under the ignition lock), it should work without any help from the dealer.

Bob, could the tampering attempt have damaged the PCM in some way? Would that account for the cost maybe?

I don't think the PCM would be in danger unless the brother/perp did something really foolish. I'm visualizing a bunch of cut wires and possibly a smoked PATS module. The dealer probably built in a good $$$ cushion to be sure they had their time covered. I would in a situation like that - too many unknowns.

although its very unlikely someone will have an identical cut key as your truck though...

Yes, but the whole point is that the cut of the key isn't the ONLY security. The system you described is nearly useless in terms of adding any security for anyone who knows the "secret".

Uh no you can't. I have 2 spare keys and then just a spare metal key to unlock the doors, that metal key will not start the truck.

Once you have 2 "original" keys it just gets easier to program the keys and you can do it yourself. The other keys still need to have a chip and need to be programmed. You can even buy keys on ebay take them to a locksmith and get them cut for cheap and program it yourself. The 2 "originals" are expensive though, anywhere from $100-$150 from the dealer.
