Getting in a vehicle

I need help with getting my guy into a plane/tank/car and others. He has a main, and weapon camera. The vehicles have only a main camera. I need something like this. (My guy is first person shooter) When my guy gets close to a vehicle he can get in when I press a button. His controls and camera are deactivated while the vehicle's are activated. When I press the button he can get out, and his controls and camera are activated while the vehicle's is deactivated. Please help, I am new to scripting and Unity. If there is a better way please show me
