If u lose your phone you can always send a sms to a friend to do a computer search.
I had to "knock" my door down 3 times in my old flat because I had forgotten my keys, good to know where to hit a door so that you can't break it. Dad buildt in doors for a while on building sites.
My new house has a key code to open the door, so no more forgetting the keys. Yes I can programm the code, so I will never forget the code.
