Is there a device to find misplaced house and car keys
My 93 yr.old Father and 83 yr. old Mother are having memory problems. My Mother is especially agitated and frustrated, and has become paranoid etc.etc. etc... blaming my poor Father and now even me! For stealing her keys. She keeps hiding them, losing and forgetting them. I was wondering if anyone knows if there exists >a device to find misplaced house and car keys. Sometimes when I misplace my handset of my wireless telephone, I am able to push a button on the base part - which then causes the misplaced phone to beep. So, I am wondering if there exists anything similar to this that I could possibly attach to her keys etc. Thanks.
