Although I don't have a TV, and thus no a remote for it, I do use one for the stereo when I listen to audio books...and I (almost always) put it in the same place. But I have also misplaced it and then found it:
- on the bathroom counter
- on the kitchen table or the counter
- in the pocket of my house coat
- in the pocket of my sweater
- next to phone
- next to the computer mouse
- on the stereo

Good luck; hope that you find it .

With love, Erika
