Hello, I have a suspicion the battery for your key is dead or dying. When the key will not turn, the IR sensor is not able to communicate with the ignition switch, or the shift interlock system is not allowing the key to turn. Try giggling the steering wheel and gear selector while turning the key back and forth. If it doesn't work, move to the outside of the vehicle, lock the doors with the key fob, and unlock/try to start. If the remote will not unlock the doors, change the batteries before proceeding.
