I personally prefer to only unlock the drivers door with the first press. I don't want ALL the doors unlocked, just mine. If I have guests, I'll give it another push.
Getting into the car by myself in a dark downtown parking lot can be creepy from time to time, even if it is "gated". I like the security of only one door unlocking on the first press.
I do see the benefit to the other side though, and think it's cool you can reprogram them.
Now to figure out how to roll the windows down with the fob. Our Audi was reprogrammed to allow that feature. All windows down with an unlock hold, all windows up/sunroof closed with lock hold.....Oh yea, Auto up/down for all 4 windows is something the Audi does that I would like the Focus to do too.
