The problem usually comes when I realize that my truck and house keys are buried somewhere under all that mess, and that I will be spending most of my day looking for them. The other thing I will admit to you is that I am also not the most punctual person either, which leaves me racing out the door without my keys on a daily basis. This then leaves me crawling through a window or smashing my new key lock box (that I forgot the combination to) with a hammer to get the spare.
The point is, I always knew there were better locks on the market that would make my life easier, but guys are a strange bread. Not carrying a pocket full of keys is a strange feeling for me. Think about it, whether it's a car, house, boat or safe, everything that is valuable to you takes a key. That being said, by the time you add up all the metal you have hanging from your key chain, you probably won't even remember what key works with what. Not to mention, replacing you prison guard key ring would be a real pain in the butt.
