It might be important to know if you want the 'actual' switch that's mounted to the column(can't be seen) or key & cylinder that you twist/turn. Many get confused. You would have no problem with a 'local' buy for either BUT maybe you might mention why you feel you need whichever.

^^^ This ^^^

The ignition lock cylinder (that you inert the key into) is a separate component from the ignition switch. I don't think you will have much trouble tracking down either part though. Maybe 30 or 40 bucks for either part. I'm guessing on that but neither are really expensive parts.

Welcome to the Forum! '84's are fun! Which part do you need? I have an ignition switch from an '84 (that mounts on the lower part of the steering column) if that's what you need. Send me a PM (click on my moniker).

Put the Factory Service Manual (FSM) on your wish list. It's worth its weight in gold!

I cant remember if the 84 model car has the vats theft deterrent system, if it does, then that could be a problem.
If not, then you just need to replace the ignition lock cylinder.
You might be able to get one at the local napa store or autozone or whatever.
Its pretty easy to replace, provided you have a steering wheel puller and the column lock plate tool.
Its very difficult to improvise if you do not have the column lock plate tool. You might get it apart, but you wont get it back together.
You might want to just pay someone who has the equipment, and have them do this. Its not an expensive repair.

No VATS in the '84, so that makes the job a little easier. But the problem with replacing the lock cylinder is that you can't get the lock cylinder out of the column without using an ignition key!

It's time to call a locksmith. Sorry.

This is correct - an easy removal/replace requires an ignition key to rotate to RUN

Where is the car? Home with you or somewhere else? Is it easily accessed? Has the car run recently before the key was lost?

For a 'damage free' replacement the locksmith is the solution. Could save you $$$ in longer scheme of things.

Other options? Yes but I'd recommend it only for very experienced persons with the tilt/telescopic column.

Be sure to mention to the locksmith that the car has a NON VATS column. Some might just assume all C4 have VATS and price the effort accordingly.

I'd be maybe interested in what price you're quoted and where you're located. A busy metropolitan location might carry a very high price tag. A rural/smaller community it could certainly be a much better experience.

If you felt the '84 was worth the price to buy then the $$$ to accomplish the cylinder replacement correctly shouldn't be an issue. If you don't have door key then the locksmith should be able to use the console lock to create you a door key also if nothing has been changed.

Man that's crazy. I don't remember the key being required to pull the lock cylinder. I'm not saying that isn't the case, but I don't remember it that way.
Anyone have a few pics of the inside of the column ?
So if the lock cylinder is seized and you have the key, can you still disassemble it in the way its intended ?

I did mention talented and experienced tilt/telescopic. This covers cylinder and then you've the removal of parts to get there and then reassemble.

Where is the car? in a barn about thirty miles from my house



Home with you or somewhere else?
Is it easily accessed?
easily accessed


Has the car run recently before the key was lost?
yes it was started about three months ago.

yes the locksmith will make a key for $300.00
Other options?

Yes but I'd recommend it only for very experienced persons with the tilt/telescopic column.

Be sure to mention to the locksmith that the car has a NON VATS column. Some might just assume all C4 have VATS and price the effort accordingly.



If you felt the '84 was worth the price to buy then the $$$5,000 to accomplish the cylinder replacement correctly shouldn't be an issue. If you don't have door key then the locksmith should be able to use the console lock to create you a door key also if nothing has been changed.

thank you

$300 seems quite high - you haven't mentioned where you're located. Was that a call you made before posting and knowing about the NON VATS or ......


If it ran 3 months ago and there were keys - who lost the keys? You or the previous owner or you maybe haven't bought yet?

Ok now I think I remember what happens without the key.
You mangle the key buzzer switch, because the switch contacts are in the "open" position and the top piece is caught in a groove on the lock cylinder. By inserting the key, the tab on the cylinder pushes the buzzer switch contact out of the grove and against the other contact, only then does the cylinder come out without resistance. Plus, theres a plastic tab on the buzzer switch that overlaps the cylinder retaining bolt head.
