Someone at my office has a VW with that huge silly keyfob thing, I've had PDA's that were smaller, talk about not being able to fit in a pocket. I think it broke like everything else in the car too, I wonder if the weight of the fob on the ignition switch is part of what contributes to VW's electrical gremlins.
I carry one of these http://www.wilsonsleather.com/product/index.jsp?productId=1835289
with my most of my keys, a small knife (Gerber ridge knife with the money clip removed) some first air supplies, a stack of $, and my USB flash drive. This makes a tiny PSK wallet which has my house key so I don't leave home without it. The truck key, keyless bfob and arc aaa are separate.
