Default Please help! Ignition Lock stuck!!

My ignition lock took a crap during the first start up off my new motor The starter stuck ON and i had to disconnect the batt cable to turn it off. Talk about scrambling for a wrench

So my delima is: All of the manuals I have read disagree. Some say remove the steering wheel, others say different. So I have removed the steering wheel and everything else and still can not get to the lock.

I think the problem might be: I cannot turn the ignition to the "lock" position, it is stuck ON.

BTW car is a 76, no tilt, cruise or anything else.

Any suggestions???

Thats a strange one. I suspect the bar that runs from the ignition to the electronic switch is jammed.

Lie on the carpet and look up. You should see a switch...small rectangular shaped thing...its above the column...wires will be going to it....on the other side will be a rod...thin like a coat hanger...goes from the switch to the key area...I think your problem is there. When you turn the key the bar clicks the switch to the start position...it springs back when you release the key...sounds like yours is jammed on "on".

To get the cylinder to the lock position there is a cable acutated lever on the steering shaft right by the firewall(engine bay side). That has to be all the way up to allow the column to lock.

All screws are removed. The housing that contains the ignition is completely disconnected from everything. No screws, no nothing left except the piece of the steering column that contains the ignition switch and the wire harness.

From my new lock it looks like the is a "tab" on the switch that locks it in. However It is basically unreachable. I appreciate all the suggestions.

It is pretty frustrating to fire up a brand new motor, have it run for 3 minutes, and then have the ignition switch go bad

On the plus side the motor seems to ROCK

from Jim's article

If your steering column has never had the lock cylinder removed or replaced, there will most likely be a thin metal die cast membrane covering the slot. Keeping a thin bladed tool to the right side of the slot, break the housing flash and the same time depress the spring tab at the lower end of the lock cylinder. Also I have found that if you don't push the spring tab pretty much in the center it will not release the lock cylinder because it tends to rock side to side. Don't be tempted to pry on the lock cylinder wings to get the lock cylinder moving. The wings will pop off and can't be put back on. The lock cylinder should slide right out.

But if the lock cylinder is jammed,think going to the switch at base of column to free up adusting rod is the way to go...you have to remove the switch...a real pita lying on your back..

If I remember correctly there is a screw in pin behind the key busser switch holding it in. The key needs to be in the on position to get it out but it was last year when I did mine. Happened to me when I had new keys made then none would work right outside the hardware store. Finally got it to on position to get home. My is a 79 tho might be different.


Good luck

Just to clear up some terminology. The ignition lock cylinder is located in the steering column housing and is where you stick your ignition key. It is held in place by a thin metal tab that is spring loaded into a slot that is molded into the lock cylinder housing. The tab was used to hold the lock cylinder in place from 1969 through early 1979. The tab was eliminated midyear in 1979 and was replaced by a screw.

The ignition switch is down under the dash on top of your steering column.

The slot with the thin die cast skin is exactly 1.75 inches measured from the edge of the housing boss as shown below.

I'm confused. What are you removing the key cylinder or the ignition switch?

The key cylinder will not come out unless the key is in it. Can only be removed in the "run" position.

Not true! If the key is in the ignition lock cylinder, you must turn the key and switch to RUN. If the key is not in the ignition lock cylinder, you can just depress the tab and remove it.

If you are far enough along to just remove the lock cylinder from the column, you can then play with the cylinder and key and determine if the lock cylinder is operating correctly. You should be able to insert the key into the cylinder and it should smoothly rotate from START; to RUN; to OFF; to OFF-LOCK; and then you need to push in on the key to reach ACCESSORY. What you feel between START, RUN, OFF, and OFF-LOCK are the detents in the switch down under the dash. They are not in the lock cylinder itself. Unfortunately, I do not have the angle that the key should rotate through from START to OFF-LOCK.

If the switch feels good, your sticking problem is in the switch under the dash or it is in the plastic sector and die cast rack inside the steering column.

Doesn't inserting the key depress the Tab? Just curious.

In order to remove the key from the lock cylinder, the lock cylinder must be in the OFF-LOCK position. In the OFF-LOCK position, the plastic tab sticks up with the key in place, it drops down into the lock cylinder when the key is removed.

Now, with the key in the lock cylinder, in all positions (except RUN) the key would cause the plastic tab to stick up. This could damage the key warning buzzer if you tried to pull the lock cylinder with the tab sticking up.

Thansk Jim. Part of the problem was that I could start the car without the key in it So even without the key in, the plastic tab was sticking up. I was able to get it pushed down with a small screwdriver, but for some reason I can't depress the lock cylinder retainer?? I have "fished" for it with a small screwdriver and a piece of metal but it feels like the tab doesn't move and is locked in place.
