Changed to the lock when walk away function and looked on as nothing happened.
From the Manual
Note: Walk-Away Door Lock operates only
when using an authenticated phone. When
you walk away from Model 3 carrying a key
card or the key fob accessory, Model 3 does
not automatically unlock/lock, even if this
feature is turned on (see Walk-Away Door
Lock on page 13).
Using Exterior
Works fine with the App, also sound notification, so you don't have to watch or keep looking back.
Controls > Locks > Lock
Confirmation Sound > ON.
