There's a bunch of threads and info on replacing the lock cylinder and they all say you need to put the car in ACC mode to remove the cylinder. That isn't going to happen, its stuck hard between OFF and ACC. I have a new OEM cylinder on order. The GM service manual has instructions which involve removing most of the dashboard trim and the steering wheel and column. Argh. One post said it was possible with the column in place and I'd really like to find more info on that. Can anyone assist?
For future reference, the TSB is BULLETIN NO.: 95-T-20
SUBJECT:
Ignition Key Cannot Be Removed from Ignition Lock Cylinder (Replace Ignition Lock Cylinder, Tumblers and Springs, and Cut New Keys)
MODELS AFFECTED:
1994 Saturns with VINs between RZ205000 and RZ240000
(and I think this was a problem across a lot of years and models)
Keys and tumblers wear out wear out over the years. Dirt gets into the tumbler areas and binds them up. One day you find the parts have worn so much you can slide the key right out of the ignition while the car is still running. A combination of things occurring all at the same time. If the key is still locked in placed and you're replacing all that, I'd suggest getting some WD40 (liquid), not in a spray can. Don't want it spraying everywhere or force it into areas you don't want it to go.
Get a small glass or plastic jar like a jelly or baby food jar. Pore some liquid WD40 in it. Get yourself a syringe with good long tip on it. If you've seen those 2 to 3 inch long extension type ends for Syringes used for refilling Ink Cartridges, they're helpful in getting the liquid WD40 into specific areas to clean, loosen dirt, and lubricate things such as outside locks that water has gotten to. I've found them to be very useful putting WD40 into many small specific areas.Take the cover off around the key area, which you've' probably already done if you're going to replace all that. That is to avoid contact with the dripping WD40. Draw some WD40 into the syringe, go all around the entire outside area and lubricate where you believe something may be clogged up. You'll find those long extensions tips on the syringe may help you get the WD40 even into the key slot, using the key locked in place itself to channel it in further. Not such a mess if you use the WD40 Spray. Let it sit in there for as long as you can. While your at work or overnight if you have the time. Longer the better but it may work within minutes to hours, all depends on a lot of factors.
Get you some old rags or paper towels to catch dripping WD40. If you do a lot of auto work on your vehicles, especially changing out oil and fluids, I'd suggest going to Sams Club or Walmart buy a box or package of those puppy Dog Training Pads. You'll find that overtime it will save you lot of money instead of using those expensive Blue Shop Towels to catch drips and clean up large fluid spills. Big benefit, they have a plastic lining on one side and absorbent pad on the other. You catch the spills and dripping liquids, wrap it up and throw it in the trash. Save your Walmart plastic bags to put the used pads in. No mess under the pad to clean up like you'll find left behind using blue shop towels or rags. One drawback I found was with Transmission Fluid, not so much with Engine Oils. If there is a heavy concentration of it in one spot of the pad it will start softening and eating the plastic of the pad. Not immediately so be watchful of that when catching any fluid spills other than water.
This of course is suggested if all else fails trying to get the key out. Hope the info helps in this situation. You may find the info useful for future situations where the WD40 may help you. I suggest after using the Syringe put it in a small plastic bag you can seal and store it close to the small jar of WD40, I'm sure over time you'll find another use for it even if it doesn't work in this situation.
