Re: Replacing Ignition Cylinder

Year of car?
Tumbler replacement? Have key?
Is the electrical portion needing replacement or just the tumbler(lock cylinder)?

Re: Replacing Ignition Cylinder

It is for a 68 Convertible Camaro. The car did not have the keys when I bought it, so I am just replacing the ignition cylinder. I bought keys and a new ignition cylinder from NPD.

Re: Replacing Ignition Cylinder

I suspect that you want to replace your ignition lock cylinder. Up until 1969 they were mounted in the dash. You need a paper clip and your ignition key to remove the cylinder from the instrument cluster (1967-1968).

From 1969 forward they were installed in the head of the steering column. What year vehicle? If you have a column mounted cylinder, do you have a standard (non-adjustable) steering column or a tilt? You will need a few more tools to remove the steering wheel, hub, and locking plate. More complete information is available at www.corvettefaq.com in the A&F-Car Steering Papers section.

Re: Replacing Ignition Cylinder

Thank you, it is a 68 Camaro, I do not have the keys for it. That was the only issue when I bought it.

Re: Replacing Ignition Cylinder

Okay, no key so you will need a set of locksmith tools to set the tumbler and the anvil to turn the cylinder once they are set.

As Jim said, use a paper clip and push into the hole and at the same time, turn the cylinder to ACC and the lock cylinder will unscrew out if its body.

Reassemble with the new cylinder and key in reverse without the paper clip, or with the paper clip.

Re: Replacing Ignition Cylinder

Or you can remove the bezel on the dash that holds the cylinder/ignition swith assembly unplug the switch and remove it from the car. Replace them both at once and you won't have to worry about picking a lock. I've tried doing this before and I don't have the patience to mess with it. I think you can get both parts for less than $40.

Re: Replacing Ignition Cylinder

I appreciate all of the feedback. I will more than likely just buy the ignition switch as well. It sounds as if it will be much easier to do it this way. I am not sure if I have the patience to go through picking the lock as it seems tedious. Thanks again for all of the feedback. I will let you know how it goes.

Re: Replacing Ignition Cylinder

If I remember correctly, you have to remove the tumbler first to remove the bezel nut to remove the switch from the dash.

Re: Replacing Ignition Cylinder

You may want to try an old key for 68's. Sometimes those switches are worn to the point that another key can work. If so, you can use the key with the paper clip to remove the cyl.

Re: Replacing Ignition Cylinder

I found this information in one of my files. It came from a very knowledgeable engineer so I am pretty sure it is correct.

REMOVING INSTRUMENT PANEL MOUNTED IGNITION LOCK CYLINDER - WITHOUT A KEY - (REQUIRES A NEW LOCK CYLINDER)

Take a 1/8" bit and drill to the side of the key slot (the side with more space). Drill about one inch deep. This will make the lock mechanism no longer functional. You should now be able to turn the lock cylinder without a key. Turn it back a click, insert a paper clip in the little hole and the lock cylinder will slide right out! AFter cleaning out the metal shavings, insert the new lock cylinder. Task complete.

Good luck,
Jim

Re: Replacing Ignition Cylinder

I replaced the cyliner only on my car. I did have the key but I am not sure if you actually need to turn the barrel once you have the paper clip inserted. I think that if you can find a gm key that will fit in the ignition but not turn I think it will work.
I did it a couple of years ago on my 68 and I can't remember if I had to turn it or not.
The barrel was very loose and sometimes would not start the car. With the new barrel in the old switch it worked perfectly.

Re: Replacing Ignition Cylinder

Take one of the door locks to a locksmith and have a key made.
