207 tiptronic starters never press

I just came home from work, parked, got out of the car, locked it from the remote, then I did not like the park I made, opened it from the remote, got into the car, inserted the ignition key, it sounded like a vızzzzzzzzzz, but the key seems to be wasted, the car does not work, I tried a few times, no sound does not work No key seems to be wasting, the steering wheel is too hard as it is locked, the radio lights central lock is all working, my 2009 model f1 tiptronic vehicle, it has been a week since 2.h 76 thousand km what could be the problem, thanks in advance.
