Almost all car owners have complained about the range of the keys that allow them to unlock their car remotely. These keys may not work and get on our nerves when you move away from the car. Here is a very interesting way that can solve this problem to some extent.
What we’re talking about is the method that has been circulating for many years, but no one is sure if it’s real, telling you to hold the key to your head when you can’t open your car while you’re away. While this may sound like a made-up method at first, it really works. Well how? Let’s see.
Let’s first understand how car keys work
We’ve known for some time that car keys, which have functioned as remote controls, have replaced traditional keys. These keys allow us to open the vehicles from certain distances without having to come near them. In fact, they have benefits such as helping us find lost cars in large parking lots, saving them a lot of trouble.
Let’s take a quick look at the basic logic of these tiny devices that we use every day in many places from garage doors to vehicles. These switches can be defined as small transmitters that actually send certain codes to their receivers. The unique codes they send ensure that the vehicles only work with this key. In this way, unwanted situations such as thefts are prevented.
If you hold the key to your head, it is possible to unlock your car from longer distances.

But keys that work by sending encrypted signals to our car have a very limited range. Although distances may increase in new vehicles, we can say that they generally have an average of 15-20 meters of coverage. This can make it difficult for us to lock or unlock our vehicle when we are away from it, and may even prevent us from finding it if we lose it.
This is where the key-to-head trick comes into play. If you hold your car key to your head, you can see that the car is unlocked from places where it would not normally open. It is seen in many videos circulating on social media that this method really works. It has even been the subject of Top Gear, one of the world’s most popular auto shows. In the program you can access above, you can see that this method works again.
How is this? The answer is actually very simple: the fluids in our heads
The reason why this method, which sounds like an urban legend, works is actually quite simple. The switch’s range is slightly extended because of the “water” that we all have in our bodies and heads. When you hold the device to your head, the signals pass through a high number of water molecules in your brain. As these waves pass, they pull the positive charges in the water in one direction and the negative charges in the other direction.
Professor Roger Bowley from the University of Nottingham in the United Kingdom also states that the protons act like a radio antenna by moving up and down. In Bowley’s experiment, it can even be seen that the distance is increased when a separate bottle is supplemented with water.
So you see, the fluids in your head make your body act as an antenna and this method works. Engineer Tim Pozar, who made a statement to the New York Times years ago, also uses the following statements about this method: “When you hold the key to your head, all the liquids in your head become a good conductor. While they’re not great, they do work. Using your head can extend the range of the key several vehicle lengths.”
In short, this method, which seems like magic, is completely real and has a very simple explanation. Don’t forget to use this trick next time you’re too far from your car.
