Doesn't keyless access (keep the fob in your pocket and touch a door handle to open a door) make this obsolete?
It's all about not having to carry anything where it can be lost, damaged, or rattling around in your pocket. For example, when you go; biking, hiking, skiing, swimming, boating, or out in a finely tailored suit for that matter - anywhere you don't want to carry your keys. When I meet my buddies at the trail head for a mountain bike ride, they are all clamoring to leave their keys/fobs in my Explorer.
Like I said, it is one of those things that you don't think you need, until you use it - then you wonder how you could ever live without it!
