I have a strict rule that I must touch my keys before closing the front door, because I discovered the keys in my memory don't open the door as well as the keys in my pocket.
Same. I have a "keys-wallet-phone-pad" routine in which I make sure my pockets contain all of: my keys, my wallet, my cell phone, and the 7-inch tablet that I carry everywhere. I've gotten into the habit of doing it every time I get up if I'm not at home or at my desk at work.
Same thing with my glasses, either they're in my bag, or on my face.
