The ignition switch may fail causing a no start condition. This is not generally a theft system (passlock) issue because the security light does not illuminate or flash.

This has been going on for years. Normally I get in the car, put on my seatbelt turn key to right until buzzer stops and the car will start right up. If I don't follow that protocol it will try to turn over but won't.
