Key wont turn ignition to start my car?

-i have a 95 lexus es 300 the other day i shut off my car while the car was still in drive then pulled out my key then put the car in park now the key has to be jamed to go in and will not turn the ignition what did i do and how can i fix itbony it could be caused by a wrong key or bad electronic ignition system are both issues for the dealer. Overall your shop will not be able to resolve this by the fact that they do not have the right computer to communicate with the car and the key code and an electronic ignition system.
