1995 Tahoe ignition switch issues

My daughter called and had trouble turning the key in the ignition, After about 1/2 hour of jiggling the key, trying to tirn the steering wheel back and forth & adjust the tilt up and down the key finally turned.

The ignition switch was replaced about 4 years ago. The switch was replaced with an OEM GM switch.

She is using the most often used key - the original OEM. We haven't compared keys yet.

We might have one that is not as worn if that is possibly the problem

Any thoughts or ideas?

Thanks

it is the key and lock cylinder itself try a different key maybe even flip the key over can help. Instructions for replacement if you are stuck in locked mode below.

And if key works. You might want to disconnect the battery unless you want truck running the whole time:

1. Lift upper shroud (10) to gain access to lock cylinder hole.

• 1. Hold key in "START" position.
  2. Using 1/16-inch allen wrench push on lock cylinder retaining pin.
  3. Release key to "RUN" position and pull steering column lock cylinder set (17)from lock module assembly (15).

install:

• 1. Key installed in lock cylinder (17) and in "RUN" position.

Ensure sector in lock module assembly (15) is in "RUN" position.

• 1. Lock cylinder (17) to upper shroud (10).
  2. Line up locking tab and positioning tab with slots in lock module assembly (15) and push cylinder (17) into position.

Help?

hi, If I replace the cylinder lock assembly in my Yukon is there a re-learn procedure that I have to do so it will start and run?

I believe that it's just start and run. I replaced mine, and mine was. But mine is a '95.. I don't think they added any security chips until the NBS

Yea, too many times the key not turning is blamed on the ignition switch when in fact it is the key tumbler causing problems. You could still have an ignition switch problem but is likely the tumbler. If you change out with new and the old key unlocked the doors as well as started it then now you have two keys for all that.
