I can choose to have my Model 3 always lock or never lock when I leave. I’d prefer to have it remain unlocked in our garage and locked on the street. I realize I can set it to auto-lock and pull out my phone or fish in my wallet for the card to lock it each time, but I miss having a simple lock button on the door. Then it occurred to me that there IS a button on the door! Can the two front door-open buttons be re-programmed to open the door when it is closed (its sole task now) and to lock all doors when the door is open? I’d then set the auto-lock feature off and have a very easy way to lock the doors when I park it on the street.
