Ignition key stuck in cylinder 1994 Cavalier - 1994 Chevrolet Cavalier

I'd guess that you need a new ignition key cylinder.

No.
It could be a damaged lock cylinder, or the ignition switch.
You can disconnect the switch to see if the lock will move.

You listed all the components involved in spark timing and control- coil, ignition module, pcm, wires, plugs, crank sensor, and cam sensor.
Cylinders 1 and 4 have the same coil for both, so concentrate on that coil. You still have a good blue spark on cylinders 2 and 3? If you have spark there, I don't know about the cam sensor-I think it would be good if it works at all. You need to check if you have 12 volts power to the coil for 1 and 4.

If the key is stuck in the ignition and won't allow you to turn the cylinder to "On" or "Start" you can try gently and rapidly tapping on the end of the key [with something like a light screwdriver handle] while applying gentle turning pressure on the key. Often the tumblers in the cylinder get dirty or are damaged and this trick will sometimes get the thing to work a few times more. Hope this helps and good luck!

yes probly need new 1 u can do it urself to save sum cash. its not too hard

first make sure its position all the way in park. also try turning the steering wheel hard to one side and wiggling the key out.

when you take off dash should be able to get to lock cylinder you have to get to the back side of the cylinder i believe it unscrews its been while since did one but hope this helps

Hello foxrider.
Chances are when the wrong key was put in it may have damaged the lock tumblers.
The lock cylinders on these cars are enough of a problem using proper keys.Not very well made to begin with.
You could try a very light oil such as WD40 to lubricate the tumblers in case 1 may be stuck up into the barrel of the cylinder and gently run the key in and out several times.
Jiggling the key inside the cylinder will sometimes loosen them up too.
If you do get it working it may be a good idea to replace the cylider and key soon as it may fail you again.
I hope you succeed in getting it to turn, otherwise it may be a job for a locksmith.
Good luck with it.

Put some pressure on the steering wheel in one direction or the other this may take the pressure off the cylinder itself and allow you to do what is needed...hope this works.

sounds like u need to replace the ignition switch.
