Like when you turn the key in a car, it completes a circuit right? How hard is it to just take the wire connected to the switch and touch them together?

It was pretty easy long ago or in older vehicles. Connect the ignition circuit, the one that completes the circuit for the coil/battery/alternator, and then connect the starter circuit that feeds power to the starter motor that initiates the system to those wires and it would start and run. [Three wires](https://i0.wp.com/i.kinja-img.com/gawker-media/image/upload/s–pEKnRGXX–/c_fit,fl_progressive,q_80,w_636/18n268n6mpbljjpg.jpg).
Today’s vehicles are much more complex and hot wiring one involves bypassing and/or feeding power to a lot more systems, some that are computer controlled and need an electronic signal from a computer chip in the circuit to work. Starting these involves completing a lot more than just the ‘run’ and ‘start’ circuits. Extremely difficult in most cases.
