First, you are not taking my time. I'm glad to help. Okay, I see your concern as far as switching fuses. The only other thing I can suggest is if you wanted to pull the starter relay under the hood. See pic 1. If that is removed, the starter will not engage to start the vehicle.
If you remove the coil wire, unless someone has one with them, they really aren't going to get it to start.
One other thought. If you purchase a door lock cylinder from a salvage yard and switch it with the one in your door, then you could lock it. Honestly, I can't imagine it would cost more than 5 dollars from a salvage yard. It's just a thought.
Please feel free to let me know if you have questions. If I can help, I will.
Take care,
Joe
