Extending the Range of Car Key Remotes by Touching Key Them to Your Head-Truth!

Summary of eRumor:

This is a forwarded email with a link to a YouTube video that instructs viewers on how to extend the radio range of their car key remote.  The tip is to touch the key to the head.

The Truth:

This is true.

Touching the key or remote device to your head will extend the range, which is a handy tip when looking for your car in a crowded parking lot.   Some tips suggest touching the remote to your chin others suggest the side of your head.   Both will improve the radio range of the key remote.

BBC’s Top Gear host Jeremy Clarkson first demonstrated this tip on his popular automotive program around 2007.

How this works does not take a degree in rocket science.   A member of our TruthOrFiction.Com Team is an amateur radio operator who said that touching the radio control key device to your head will improve its performance because the body has becomes the antenna for the radio transmitter.   This is similar to the effect you get when adjusting the rabbit ears of an old TV set and noticing the reception improves until you walk away from the set.

Doing this is safe and will not harm the body as the transmitter power is very low.  It is no more harmful than using a mobile telephone.
