2000 Buick regal, ignition / key problem. I have googled all the key words, and read all i found. NO LUCK. The key in the ignition will not turn. I have tried the tricks with the shifting console / wd40, up and down, no luck. By the way i managed to remove the switch and managed to start and drive the car by starting the car with a screw driver, BUT THE KEY WILL NOT TURN. please help

    The white wires are intact, target is to bypass the anti-theft all together. I was going to remove the cylinder and blank it out, so it will turn, on any key (of course in our case the original w/chip key).
    Is there a way to disarm or remove that function all together?

    I have pulled out the halo from its original place and also pulled out the ignition switch. The car starts and runs and drives fine. I would like to put back and turn the key like I used to w/o all the security stuff with the key cylinder.

It sounds like the anti theft lock is engaged. There should be 2 white wires hooked to the ignition. they are very easy to break in the halo surrounding the key. They measure resistance in the key itself. there should also be a plastic piece just behind the lock cylinder with a silver rod coming out of the bottom of it. That is the anti theft. If the wires are broke in the halo, it will not allow the rod to punch up and the key to turn. Take a ohm meter and test both wires. if with the key in you get no resistance measured, your halo is broken. You have to replace the lock cylinder and key. Then take it to the dealer to have the computer reset to recognize the new resistance setting.

Sometimes after I put my 2000 Buick Regal LS in Park and turn off the engine the ignition switch not the key gets stuck in the on and acc position. What causes this to happen?

Replace ignition switch (the tumbler portion) seems like its hanging up, and you shouldn't be able to remove the keys unless the switch is off.The park safety switch possibly. This switch tells the vehicle its in Park. Hope this helps.

2000 buick regal key gets stuck and car will not turn over

The stuck key could be the following. There is a cable that runs from the gear shifter to the ignition switch. Jiggle the shifter in park and simultaneously gently move the key to off and pull the key out. The key in and not fully turned to off will drain the battery.

I lost my keys and have to have a ride but i havent got the money to get a key cut. i need to know how to hotwire a 00 buick regal.

you can just try taking off the steering cowl and unscrewing the black cap (multifuntion switch/ignition switch) what about the steering lock?
If you have lost the keys forever then you may as well drill out the lock? youll have to buy a new ignition barell anyway.....
It's likely the car is immobilised though, it needs the proper key! although sometimes the immobiliser is disabled, sometimes it works sometimes it dosent...
good luck!
Leave feedback please.

2000 Buick Regal won't start. Back window

If you turn your key forward (And make sure the fuel pump kicks on) Cross the starter terminals with a screwdriver. If the car starts like this you have a bad ignition. You can replace the cylinder or the whole column.

2002 buick regal won't start

I have a 2003 buick regal. I found a small cover or tab about 3/4 of an inch square under the bottom of the steering column cover. If you remove that tab and take a thin object , like a phillips screwdriver and shove it up that hole it will release the ignition so you can turn it back and pull out your key. What a great discovery!
