Key Won't Turn

I have a Final Edition 2010 Beetle, and I can't get the ignition key to turn. Others have started it with little or no trouble on different days; I am told it usually takes a little force. An internet searched indicated this is a common if intermittent problem.Today I have alternated keys, removed and turned the keys 180 degrees before trying again, turned the key back before trying to turn it forward, and pulled on the locked steering wheel, all while pushing the brake pedal and wearing the seatbelt.I called the Dealership for tips, they said to "force it, the key won't break." A little force has not worked, I am not ready to prove, or disprove, their theory that the key won't break. Do you have any ideas?
