Definitely use Forscan, especially if you're using it to make deliveries. You can also use it to enable Secure Idle so no one can steal your car while you're away from it

#4 is by far the best option. Forscan can do this and tons of other things, and is very easy to use, especially in newer Fords. I live in a city, so I'm not leaving my door open. There's also the probability of rain or snow getting in the car. Get you an ELM327 and Forscan, and pay for the premium license. It's well worth it
