Key will not turn

I have a 1991 BMW 520i and I drove to a couple places and then when I was about to leave for work, I tried to turn the key and it won't turn and the steering wheel won't lock up either when the key is not in the ignition.

Spray some WD40 into the lock and see if that helps but it sounds like the key is starting to wear. This is caused by putting too many things on the key chain and it wears a lot faster

I drove my 1985 325 bmw today no problems, parked it & now the key won't even turn & the steering wheel is locked. Is there an anti theft thing that is causing this?

No it sounds like a problem with the lock cylinder. Spray some WD40 in the key hole and move the key in and out a few times then try it. If it doesn't work you might have to replace the lock cylinder. Also you could try a different key.

My 520i drains battery overnight

This is obviously a wiring problem, I would start testing all circuits with no key n the ignition to see which ones are drawing power. The first circuit I would check would be for the starter selonoid, as this would be the most practical place to start. then I would move onto he ignition. Good luck and remember to rate all the solutions you get.
