How do you all secure your planes? I mean obviously you keep it in a hangar or garage, but if your plane has a push button start, or just any way to start it without a key, how do you prevent people from stealing it?

Hidden night switch?
Unplug a wiring harness?
Keyless fob?
Lockout function on the avionics?

I'm new to this, sorry if this is a dumb question.
