I have a 10 year old Nissan. When you detach the mechanical key and use it to lock the door with the fob inside, you can't tap the door switch or yank on the handle or any of that to gain entry to the car. I haven't smashed my own window to see if it would start or not. My guess is it would.
This has worked with a few Audis rented in California, however the most recent one had the mechanical key hole hidden under a plastic piece that had to be pried off.
I had a Pathfinder in PR and the can't-lock-fob-in-car bit was more sophisticated. I was able to get it to work by putting the fob in the glove box but just leaving it in my shorts pocket was a no go. In that case you might need a Faraday bag to put the fob in.
At this point between real estate, traffic, crowds, etc. it would be cheaper and less hassle to sell all, move someplace in Sub Saharan Africa, and buy off the local warlord.
