Well sinxe your keys, wallet and phone are something that constantly moves and changes position with you, that might be the problem.

Let's take a few examples, an alarm clock, a radio and a fountain pen.

An alarm clock is something that would have a dedicated place, most likely right next to your bed. Something you rarely, if even, move. Not really a problem I suppose.

A radio is an item of semi movement, you take it places but generally it's rather big to get easily lost or extremely easily like a pair of keys. At most you might forget to take it. The most modern counterpart to it could be a JBL speaker.

A fountain pen is one most similar to your keys, small, probably moved to many places, and around your home, a lot if you are a student or just prefer pen and paper. Easiest to lose most likely and to forget about.

So as you see, the organization added to manage really depends on the items you have or decide to incorporate into your life. Very much you should take into account how stationery it would be and how, or if, you would lose it.
