2018 Nissan Leaf with possibility of a Kill Switch

[StevenAtRocket]

I was wondering if it was possible to install a Kill Switch on a 2018 Nissan Leaf.

With stories of cars being stolen by taking the FOB from the driver and or duplicating the signal.

Either kill switch or put they key in faraday cage.

If I had to make it up I would add a parallel switch button with start button.
So start button has no effect as it breaks the circuit for start button.
