Having multiple issues that started with the key would not turn off the vehicle?

When turning the key over, the car started but the key wouldn't turn off the vehicle. I also couldn't move the transmission and no gauges worked. To solve that, I disconnected the battery and basically wiggled the ignition and key until it turned back over, and I got the key out. I reconnected the battery, then I put the key back in to the ACC mode and set the car in neutral and started it. The car started with no issues but only the gas gauge worked (no MPH, RPM or temperature), and one headlight worked, and the key was stuck once again. However, since the car was running, I felt it would be better to check it again in my driveway. While driving home, the car shut off randomly (no power wheel or brakes and no acceleration) but it turned back on once I was able to pull over and put it back in neutral and crank it. When I got home I disconnected the battery once again and managed to get the key unstuck but this time I paid more attention to how to get the key unstuck and pull it out, I had to push it all the way over in the crank position and pull on the key while slowly turning it to the off position.
