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. I'm sure it's in my thread someplace. 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
