When we think about personal safety, rarely do we consider the key fob as a tool that could potentially save lives. Yet, this compact device that grants us access to our vehicles also holds some untapped potential for protection. Check out this practical tip could come in handy in dangerous situations.
The Science Behind the Technique
Most key fobs operate using radio frequency signals. Normally, the range of these signals is limited by the power of the transmitter within the fob, typically a few hundred feet. However, by using your body as a conductor, you can extend this range significantly, sometimes 2 or 3 times the normal range. How? Well, your body is composed mostly of water, a good conductor of electricity, which also means it can help to amplify radio frequency signals.

How to Do It
To extend the range of your key fob, simply hold it under your chin, so that it touches, and press the button to unlock your car. The fluids in your head will act as a conductor for the key fob’s signal, boosting its range. This technique can increase the signal’s reach by a surprising amount, often giving you 2 to 3 times the normal range.
Risky Situations
Imagine you’re walking to your car in a dark, empty parking lot and you sense you’re being followed. The longer it takes to reach your car and get inside, the more vulnerable you are. By extending the range of your key fob, you can unlock your car from a greater distance, allowing you to enter it more quickly and potentially evade a threat. You also have the ability to activate the panic button at a greater distance, potentially scaring or distracting a potential predator.
No Need to Panic
But this trick can be handy even if your life isn't in danger. Finding your car in a crowded parking lot can be easier when you can activate the car’s alarm system from a greater distance. When in large parking lots like a Costco, or Disneyland, this trick can give you the extra range you need to find your car quickly and save yourself wandering around the lot for ages.
Safety First
While this trick is handy, your safety is paramount. Always be aware of your surroundings. If you ever feel threatened, remember that your primary goal is to remove yourself from potential harm. Your key fob’s increased range is just one tool in your personal safety toolkit.
