    The Only Way To Disable The Anti-Theft Function Of The Ford ECU Would Be To Delete That Parameter In The In The ECU.. If The ECU Is Not Equipped With An EPROM You Will Not Be Able To Write The Anti- Theft Function Out Of The Program

Yes its possible to disable the alarm immobiliser ,remove the ECU unit .then solder in a 12v supply from the on side of ignition,find a suitable connection in the wiring harness feed and solder to a switching transistor on the side of unit with a heat sink to the base connection of a transistor that controls the feed to another three transistors ,starter motor earth for relay,fuel pump earth relay,and ignition ,no relay and away you go location of transistors iam not saying as i dont wont the car theives reading it ,but its as easy as falling off a log when you know the colour of the wires, pin numbers and a magnifying glass soldering iron .took me hours to follow the the connections in the fuse box separating the two halves to follow circuit,tracing wires back to ECU then following printed circuit but i have done it .SO DEALERS EAT YOUR HEART OUT ANOTHER FOOD WITHOUT WORKING FOR IT JOB LOST .going to try it out on a dammed renault when i get time.Also sell the details over the internet ???? no i dont think so iam just glad i have pissed off the local dealers that wanted 200€

    so, if I understand this correctly I only need to run 1 wire to 1 transistor? And the transistor needed controls the transisters for fuel starter and ignition? WOW that would easier than rewiring the relais

It would be impossible to disable the security feature without a programmer, the entire idea of the system is that no one without the proper key can start the vehicle, there is a program called "sniper" that can disable PATS (the security system in your car, Passive Anti Theft System) but it is costly, another idea to try is to call local lock smiths in your area, it is possible that one may have your key in stock even though the dealer does not,

Battery was dead and now the centre dash board and gear selector lights do no come on at night, I also have the anti theft light flashing which it never used to do.

Does this vehicle start? I had this happen in a 2001 Ford Freestyle. The battery was defective / deader than dead. AAA came out to jump it but nothing worked except the anti theft light that flashed, double speed if you turned it to crank, (Which it wouldn't) I had it towed to Walmart to replace the nearly new battery but it still wouldn't start. I called AAA back to tow it to the Ford dealer where I had to pay $65.00 to get the anti theft key/s and computer reset. I said "key/s" because they didn't tell me that I needed my wife's key because you can't just program ONE key. So either I pay a taxi for a 24 mile round trip or I pay an extra $20.00 for a new anti theft key. After that. I had 3 keys to that van. To make a long story short, Have BOTH keys with you when you take it to be reprogrammed.
