Will phones replace keys? Maybe. I watch my phone as carefully as I do my keys. But:
I don't want to drop my phone like I do my keys. But maybe I won't since I will have just one "key".
Is my phone easier to hack than my key? Dont think so.
My phone has my address in it. My keys dont.
I use my phone for other things than unlocking. Do I misplace it more often and lock myself out? Don't think so.

Technology that allows doors to be unlocked remotely is moving to the smartphone, causing some analysts to say the key will soon become obsolete.
