Alas for you, the integrated fob/key seems to be the way all manufacturers are going with their car keys. My best friend has always been the same way when it comes to keeping things in his pockets and got real frustrated a few years ago when he replaced his old-ass Grand Am with a new Jetta, has one of the fobs where the key part pops out at the push of a button for the ignition.
However, he did manage to get used to it after a couple of months... it really just boils down to tolerating that little bit of frustration until it becomes normal feeling. I experienced the same thing in reverse when I quit smoking, felt naked walking out without my lighter and cigarette pack in their regular spots. Just a matter of acclimation!
