Universal TV remote mini keychain can virtually control any TV set on the market today! It is very similar to the famous tv-b-gone(tm) control, but has more functions like channel changing, muting, volume and audio/video switching! It is fun and effective. You program it by pointing at a TV set, pressing the mute control button, then when TV becomes silent or "muted" appears on screen, you have control of that particular model until you try it on another TV. Never mind replacing your lost remote control... This makes a great gag gift!
