01 Yukon wont stay broke long enough to fix

Any chance that key has a chip in it that has lost it's link with the 'Kon?

A lost association will yield what you're talking about. I only say this b/c you said you switched keys, and it started right up. Has it always happened ONLY when using her keys, or both?

Just another angle to look into.

thats why i sent him the links for the vats eliminator, it is that.

But why not have the dealership quote a reprogram price... worst they can tell you is it'll cost ya $40 to reprogram (if that's really the issue).

I'd be curious as to how the bypass kit works, and what's the downside to using it. Sounds like this is to eliminate VATS all together. I wouldn't do that to mine, but to each his/her own.
