As much as I love all the innovations and creative implementations, I'm afraid to use a digital lock for my door in a place like Singapore. When I was living in Durham, it was a piece of cake to call a locksmith if I was locked out of my house. I had to call
swiftlocksmithinc.com, and they were there in a few minutes no matter what the time was. Unfortunately, it's not that easy in Singapore as the number of locksmiths is not high, and most of them don't even speak good English. It's one of the few things I miss from New York.
