I tried to start my car last night and when I turn the key in the ignition, the key physically won't go past ACC and I do get electricity in that mode. Also, my breaks didn't have much air pressure but they did work. Now when I push down on my brakes, the pedal feels hard. That started last night just like the ignition problem. The wheel is not stuck and my car is in park. I drove my car earlier that day and no indicator lights came on and the car temp was fine. My car does need an oil change but I don't think that's the problem.

The engine needs to be running to create vacuum for the brake servo unit to give you power assisted brakes, that is why the brake pedal feels hard but pedal effort is great to stop the car. You have lost power assist to your brakes. Have you another key for your car have you tried that? The ignition switch may be worn out. Is your key a genuine Toyota key or a cheaper hardware store cut key?
