I don't think the airbags will deploy with the SRS light is on, that means there must be some kind of code also. SRS stands for Supplemental Restraint System. The motherfawkers must have damaged the whole multi-switch system on the steering colomn when they broke the lock. That could be a contibuting factor as to why your turn signals don't work and your SRS light being on.

PS - Multi-switch system being your turn signal lever and the windshield wiper lever.
