if it is the steering lock, then it didn't break in open but rather in an "almost but not quite open" position. There is a little switch in the lock which is depressed when the lock is all the way open. the (depressed) switch allows the engine to begin the start sequence.

It could be a lot of things, the fact you can turn your unmodified steering lock leads my to suggest it probably is your steering lock. (which because its not locking is clearly malfunctioning)

Unfortunately you do not have an easily diagnosed common mode of failure.

I recommend the standard "emergency fix" of pushing your start button (with your key in the key holder) and tap/bang the crap out of your malfunctioning steering wheel lock hoping it will slip loose from its jammed position. If that works (really stick with it for awhile) then definitely pull your fuse or cut your brown wire once you get the car running BEFORE YOU TURN IT OFF!

good luck, unfortunately you are not talking about a standard (well understood) malfunction.

one last though. Make sure you have a good battery in the key fob or just put it in the little fob holder (if it is dead that should allow a start.)
