I don't have a K anymore and forget where there's space but here's one fun suggestion to think about:
Smart Tags. You can choose from Samsung ecosystem, Apple ecosystem, or Tile lot. At least the first two I find simple guides to disable the on board "hi thieves here I am take me out and stamp on me" speaker.
Maybe get one of each and hide them in different spots. They're so small it's easy. Battery life ranges from 6 to 12 months.
