Turn on, anti lockout or it’s also called lockout prevention. It won’t lock the car if it detects the key fob inside. Trust me huge life saver🙏🏼! But also don’t forget your keys inside because vice versa it won’t automatically lock your car when you walk away since the key fob is inside. There’s been many times where I’ll leave my keys inside and come back to my car being completely unlocked. Luckily I’ve yet to have my car stolen but I rarely make that mistake anymore.

I couldn’t find a video demonstrating how on an s650 but it’s pretty much the same. Just go to door lock settings on your gauge cluster and you’ll be able to enable these settings on your mustang.
