    Exclamation Passkey Bypass

    Ok I'm about THIS close to taking a baseball bat to my car. I'm not kidding. I can have a hot temper at times, and tend to take it out on inanimate objects. Unless someone can help me I'm selling that 4000lb. Burgandy FLOATER :madtalkin and buying a BUICK!!!!

    I measured my key to be 1867 ohm. If I remember right resisters add together when put in series. So does that mean that I have to get a 1.5k ohm and a 330ohm and a 33ohm? adds to 1863 but should be close enough for the fault tolerances. Then put them in series and splice it into the two wires that go to the ignition?

    Or would it be easier to get a varistor and just use a multimeter to set it to the correct value. Then glue it or something to stay put.

    I DESPERATLY NEED HELP!!! PLEASE PLEASE PLEASE PLEASE!!!
    PLEASE E-MAIL ME DIRECTLY at fritschrj@gmail.com if you can. I REALLY NEED THIS.

    I can't afford a key or an ignition.

    THANK YOU VERY VERY VERY MUCH.

    -Robert-

    P.S. Those little brown carbon resistors from Radio Shack should work fine right?

    Now that I think of it. You're right. I think my parents 92 or 94 Le Sabre has it.

    Re: Passkey Bypass

    My car is bypassed with a resistor and every once in a while it acts up. I have to massage the wire where the resstor is and it goes away. I guess I shoulreally look at it before I get stuck somewhere

    Re: Passkey Bypass

    I just rigged mine up last night and it works great. but I just have tape holding the wires together. This weekend when I get a chance I'll solder them together then electrical tape everything up nice and pretty.

    Time from puting the part together to starting the car was about and hour. and that was just becasue I spend 20-30 minutes reading everything I could in the Service Manual and debating if it was the correct wire.

    Thanks for everyones help. I appreciate it.

    Re: Passkey Bypass

    O.K. This isn't right. I got up this morning. Got in the car. Started the car. And looked down

    Whad did I see? The bypass module that I had built lying on the floor. I reached down and touched the two wires and they were just hanging free. But the car started fine and has flawlessly ever since.

    Am I loosing my mind or would it have just been easier to just cut the wire and let it hang?

    Anyone have any idea why this is happening? bbob?

    Thanks

    Re: Passkey Bypass

    Had the same problem on a 2000 ETC. First, a method that started the car WITH THE FAULT!
    Turn on ignition, try to start - receive failure message.
    Leave key on, place gear shift selector in N - remember to keep foot on break
    Try to start - receive same message
    Turn key off and try again - mine started every time on the second try from N with this procedure.

    I suspect it is a programmed override but not published.

    Now for the fix of adding a resistor: that worked too.
    The wires on a 2000 ETC were as stated in other internet articles - there are two wires inside a bright orange sheath that comes down the steering column from the ignition key switch. Some sites said these wires inside the sheath are color coded BUT not on my 2000 - the wires inside the sheath are covered with white insulation.
    Cut the Orange sheath and the two wires. tape off the end leading to the ignition switch, strip the white wires from the other side of the cut. Install the resistor matching your key resistance between these two wires, solder the connection with resin core solder, cover bare wires and joints with heat shrink tubing or several layers of tape.
    The car should start with the key; no error messages.
