On your Buick 94.
The problem is the ANTI THEFT SYSTEM..
If you have replaced the ignition switch.
If you are using a NEW KEY, the car won't start.
Because in the OLD KEY, is there a Resistence with a number of ohm's
The computer need the resistence to activate the the signals to operate the vehicle.
OK.. with the New Key and Old Key you can go to any Aloha Smith and they will remove the Chip from the Old Key to the New Key.
And the car must start and running.

But if you are using the Same Key that you have before the repair made.
I recomend to check the 2 Orange wires from the Ignition lock Cylinder to the steering column lower connectors.

Ok I hope this work for your problem.
Any moree info, I will glad to help you.
I'm a Mechanic and have all the repair information for all the cars.

Thank you for use fixya...

When i changed ignition on 2001 ford explorer I ended up having to replace steering column now it wont turn over & the anti theft light flashes & wont stop. what can be done to get car started?

At least you know the anti theft system is working. Jokes aside, I would think that the electronic security system is not recognising the new lock and steering column. You could try leaving the battery completely disconnected for at least 2 or 3 hours to see if the system resets. Reconnect the battery and then try again with the new key. You will have to put the security code back into your radio as well. If this doesn't work, it may need to go to a Dealer to reprogram your electronic system.

Key in ignition light

Most likely will just need the ignition switch replaced. This is the electrical portion of the ignition, not the metal cylinder where your key goes. You will need to pull off the steering column plastic clamshell behind the steering wheel to access it. It is attached to the back of the key cylinder. It is not too expensive or hard to replace.

2003 santa fa wont start, the dash board lights are on and the radio is playing but the car won't turn over.The key turns in the ignition with no resistance, we had to disconnect the battery to save it.

That means the linkage rod fell off your key cylinder. (this happens whenever someone tries to steal your car) the push rod presses your ignition switch. If you know how to pull your steering wheel off, you can replace the key cylinder (if some of the casting is broken) by going to a junkyard. Get a cylinder with a key (you can make copies of the new key later) If the key cylinder was ok then just reattach the rod and put the steering wheel back on (being careful to keep the wheels facing forward before you remove the steering wheel so that you put it back the same way)

Sunfire 1997 key not turning in ignition.

Had a similar problem with my Chevy Cargo Van..tumblers in igition old and worn, also noted key/wheel problem like yours. Be extra careful about putting in Park, keeping tension off steering wheel, and being sure key goes in smoothly. Sometimes you just have to jiggle the key and take tension off the wheel. (Beats replacing the ignition locks, etc.)

I put my Key in the Ignition and I try to start it and it wont start and the steering wheel wont turn its lock what is the Problem or how can i fix it?

put your key on the ignition and turn it and at the same time turn the steering wheel to both sides (do it with a little bit of force) and it will unlock. That's a mecanism that all cars have for security.

I purchased a key for my 2001 Pontiac Grand Prix from the dealership and have purchased 2 others previously and they worked. I followed the directions as I had in the past and this time the car will start...

In the ignition switch where the key goes is two little wires that when you put your key in completes the circuit and tells the security that it is your key. If you have someone pull the steering wheel and look where the two little wires are it is most likely that one of them is about to break. If you have the two wires clipped it will bypass the security and let you start it without a dealer key. The flip to this is the security light will stay on all the time. The only way to stop this is replace the ignition key switch or pull the bulb.
