I have this immobilizer unit on my 1995 ford f150. It sits under the dash and takes a special "key" or else the truck wont start. The key is like a chip about 1.5 inches long and has a flat side that inserts into the truck and a round part that sticks out. There are 6 wire that go to the unit. I lost the key and had to get a tow back home and I then cut the wires to see if I could some how hot wire it to be able to get to work. Does anyone know what this is, how to hot wire it, or know how to fix it? Thanks.

 

I have one too, these trucks were the #1 stolen vehicle back in the day so people would put those in, the previous owner warned me about losing it. I taped the "key" into it, took screws out and tucked the whole thing up into the dash. I believe you are proper f'd. Maybe get it towed to a shop that does alarms and they can remove it. Otherwise you gotta figure out how to "un do" it's installation. It's gonna be a pain in the ***.

 

My 96 f150 has that too but never had a key for it when I got the truck in September. Didn't know what it was.

 

Dang, does anyone know what the name of the system is called?

 

My grandfather taught me a trick when it comes to those. He was a master electrician for longer than not only have I been alive but longer than I'll probably ever live. They used to use them on Chrysler minivans and Dodge and stuff like that as well. Funny thing was they sold a bypass chip. I'm not really sold but it came with a bypass chip if you chose to. Not want to utilize the feature right. Funny thing, was the bypass chip not only just did the same thing as the actual chip itself but it was actually easier to figure it out what it was doing. It's rather comical. Most of the things were so simple. They had six wires right? And all the bypass was was a bridge between three wires onto three wires. You just had to figure out where they went in the bridge and in the cases where there were more complicated there may have been a resistor bridged in between or something similar and all you had to do was identify the resistance or whatever and mimic the same thing. I'm actually trying to do the same thing right now for an immobilizer on an F-150

 

I remove a few of those a year
One day your vehicle will not start with the key in place
It usually happens far from home, and you need towed
I would remove that immobilizer and its associated wiring pronto
I worked at a dealer where all the used cars had them installed
