Stop Start Button
In Modern vehicles we now see different methods to start the car.
One of these methods is via a start button, and there would be no Ignition barrel.
The car would still have either a Key or a Key Fob, and these would send out a frequency that when in close proximity of the car would allow that activation of the Start/ Stop button.
There was no physical need to place a key into a slot, and they would usual remain in your pocket.
Once in the car, by pressing the Stop/Start button once, all the dashboard lights illuminate and self diagnostic checks are carried out by the car.
By then depressing the clutch pedal to the floor and pressing the Stop/start button once again the engine will start.
To save two presses of the Stop/Start button you could just enter the car depress the clutch pedal and press the Stop/Start button.
The engine would start up and the diagnostic checks will still be carried out.
