How do I bypass alarm for 1994 buick lesabre

I bought this car and had to make a new chip key for it. The car starts up and runs good but the anti theft device shuts the car down after a minute of running. Is there a way to bypass the alarm system so the car will run as normal?
Thanks Tom

    I have the same problem with my 1994 LeSabre. No solutions have helped.

    I can't believe anyone here doesn't have a solution for this problem. Seems pretty basic... What kind of site is this?

    First you need to get an Ohm meter. Then take the ohm meter and measure
    the resistance of the pellet in your key. Write down the resistance you
    need, then go to Radio Shack or somewhere else that sells resistors.
    Buy the combination of resistors you need to match the resistance of
    your key. When you have it right resistance with in 5% tolerance, then
    remove the lower cover of your dash below the steering column. Locate
    the orange cable coming out of the steering column. Slice open the
    cable it should contain two small white wires. Cut the two wires, and
    splice in the resistor on the side that goes into the dash. Then tape
    up your resistors and zip tie them out of the way. That's it, the car
    will think it has the right key in all the time. The reason you haft to
    do this is because the contacts go bad in the ignition lock cylinder
    and then it doesn't send the right resistance. The alternative to all
    of this is replacing the lock cylinder and having it rekeyed with
    another key with the same resistance as your old key.

Where is the fuse located in 1998 buick lesabre to bypass security light/system


If you mean the anti-theft PASS system, it does not work that way.
You have to have power to the module, and it has to get the right signal from the key chip to start the engine.
Otherwise a car thief could start the car.

1994 buick lasabre intermitten starting problem souds like pass lock not reading key


That would most likely be a key fab problem or your passlock system which is very common on gm vehicles. You can try reprogramming the key or get a spare key and program that one. I can give you instructions if you'd like.
Another thing you can try if the anti-theft system is activated, is put key in ignition, turn to ON position for exactly 10 minutes, as soon as anti-theft light turns off, then immediately start the car.
They also sell passlock bypass systems fairly cheap.

Vehicle cranks startsup then shuts right down


Not really. Your ignition key has a little piece of metal towards the base of the key. It needs to be functional as this little metal piece is a computer chip that runs your ignition circuit. Each GM vehicle has a specific chip it uses based on your VIN number. This was GM's anti theft idea.

When i put the key in the ingintion all dash lights come on but the car will not turnover , its not the battery or starter because i tried to jump it off and it cranked but shut down how can i bypass the...


Replace the ign. lock cylinder. Put old chip key in new cylinder. Plug it in to the connector at bottom of steering column by the dash after removing the wire from old lock cylinder. With duplicate key to turn old cylinder start car. Be sure to clean the battery cables and replace bolts. Hide the new cylinder under dash with chip key in it.

1994 Buick LeSabre 6 cyc will not start after running fine


Disconnecting the battery (to replace it) has obviously reset something in the computer. I would suggest you call the service dept of a Buick Dealer and ask them how you can reset the computer. They are usually pretty helpful in a case like this

Good luck

Electronic chip in key


As far as bypassing the securtiy chip, we can't tell you that one as it would assist any user on here to steal your car (or others).
When you turn the key to attempt to start it do the dash lights dim or even go out ?
