I agree with Bryce. I always lock the doors so that it sets the alarm. I either have the top down or back widows off all of the time. I just take the radar detector with me so that there is less temptation to open the doors. I keep the glove box and center counsel unlocked to prevent damage if someone is inclined to pry open. This past weekend, we took a trip and I used a rubbermaid cargo box locked to the rear seat mounts with a bike lock so that it didn't walk away easily.
Thanks for all the responses. I have been taking the locked route, less so when the top and/or doors are off but I can’t help but wonder if additional changes take place in the computer when you ‘arm’ it from the fob. I already have what some others (on another thread) coined the millennial anti-theft device (it’s manual) but it would be nice to see a snapshot of the vehicles computer config before and after a lock
