Mine also does not beep on second press. Never heard any audible indication of locking or unlocking and tried everything.
Interesting, so it's not just me. After reading the page a little more closely maybe what I was reading on pg. 71 just refers to the key fob... There is another section that specifically mentions the outside buttons and it doesn't say anything about pressing it twice. I also looked in the '12 owners manual on owner.ford.com and it says exactly the same thing about the outside buttons which is odd.
