Airbag light came on with the first start after a couple of days sitting. (I'm at 7 months of ownership and close to getting 968 bingo - just need "pinion bearing" on my card

)
Battery seemed to be fine - it was only sitting for 4 days so I doubt it was discharged. Started right up. Oil level light came on too but it was a quart low and the light went out with a top off.
Last thing I did before leaving a few days ago was to lock the steering wheel. On my car, I have to crank the wheel 90 degrees to get it to lock. I noticed that it "pulled" the ignition switch up maybe a 1/2" in the dash housing when it locked - thought it was weird at the time but there's minimal play in the wheel or anything else wonky with the steering. This is probably the second time I've bothered to lock the wheel so I don't have much of a baseline.
So what happened? Is there an airbag sensor wire that runs through the ignition switch that could have been bent or crimped when I locked the wheel?
