eurotec :

Hi, most likely your steering lock has failed. Either that or your wheels are turned just enough to lock the column hard against the steering lock. When that happens you have to turn the steering wheel away from the lock to ease the pressure. If that isn't the problem then the column lock has probably broken and will not retract when you try to rotate the key. If that is the case the steering lock will need to be cut from the column.
