I'm guessing I'm not the only one who finds the Mazda key fob a bit bulky and annoying, especially when you're also trying to jamb your keys, wallet, phone, glasses, etc. into your pockets too. My simple solution was to go with the smallest carabiner I could find and then hook it to my belt-loop with the key fob attached on a ring. This arrangement gets the job done without taking up space in my pockets. Passing along as this may help others with the same issue.
