Extend The Range Of Your Car Remote Key Fob

You’ve done the shopping, been to the cinema and eaten your lunch. Time to go home but, wait, did I park at 4C or 3F? It was the second floor, right? If you’ve got a remote control key fob, you’ll probably wave it around in the hope that a friendly beep and flash of lights will lead you to your car, but what if you’re not close enough?

What follows sounds silly. Almost bordering on the ridiculous – but take it from us, it actually works! Jeremy Clarkson even tested, and confirmed, on the Top Gear test track.

To extend the reach of your key, hold the metal part of the remote control against the underside of your chin with your mouth open. Then press the “unlock” button. The encrypted radio signal that tells your car to unlock itself travels first into your jaw cavity, which becomes an unwitting amplifier and antenna that spews a stronger signal out of your mouth. You’ll get funny looks, but tests have shown the technique to increase the range of you key fob by several metres.

Those several metres alone could help you get home that night, instead of being forever stranded in a Sainsbury’s car park.

Have you tried this? Did it work for you?
