Could it be the CAS unit, see link
Well the leads from the lock go directly into the CAS, so theoretically it could be that (and your steering lock is otherwise fine), though I don't think this is very likely.

I think the red symbol may need clearing before the lock may work again, so if you haven't had it cleared since it appeared (before cleaning the mechanism), you may need to clear it first.

Good luck, wish I had a better answer for you
