A front-pocket wallet won't do you much good if the rest of your pants' storage is taken up by an enormous bulge of keys. The Keylet ($55) solves this problem by combining hiding two keys inside a thin, brushed stainless steel money clip with an aluminum core, combining the things you carry most in a sleek, lightweight package. If your tend to carry more than two keys, spring an extra $30 for the matching Key Caddy, which gives you four more door-opening, car-operating implements.
