I THINK this is the trick to close and lock walk away function. You need to wait a second for the first beep and THEN walk away (quickly:>). At least this is what worked for me last night when I decided to give it a try again. First time, I walked away TOO quickly. Must wait for that first beep (I think).Pretty hilarious that you have to be close enough for the key to register for the hatch to close and lock, but then immediately GTFO of there before the hatch hits you in the headSome of this technology is ridiculous.
