Among all the tips circulating on the web, this one will not fail to surprise more than one, including you, certainly! To unlock your vehicle from a longer distance, you can place the key under your chin, as if your body was acting telepathically… That would be revolutionary. Imagine: controlling all your devices by the mind? So, let’s find out some facts and investigate.
The key under the chin: sham, magic or reality?
The vast majority of vehicles are now equipped with this remote locking system, commonly known as eplip or Keyless Go in English. The system was invented by a French engineer Paul Lipschutz (hence the Plip), in 1978, and is now used worldwide. Some can no longer do without it and smile when they are handed a traditional key to start and open the doors of the vehicle. Furthermore once your Car unlocked, the success of the operation always materializes in the same way, namely beeps, horn blows and a call of the hazard lights. Before continuing, it is necessary to understand how this device works.
Open and close my car remotely
This operation is carried out thanks to electromagnetic probes which are emitted by the device and received by a sensor which carries out the operation. Your Plip is therefore a kind of remote remote control. The range distance of the waves is not very important and does not allow to close the vehicle more than 20 meters, hence the need to be close to the vehicle. This device has another function that allows the vehicle windows to be opened or closed remotely. Convenient in summer or when it rains. On the other hand, the waves can be jammed or worse picked up by another box. A method adopted by some burglars to seize the vehicle. This flaw has pushed car manufacturers to look at it differently. The latter begin to set up applications to perform this operation from his mobile, which aims to calm the ardor of thieves.
Who would have thought that? The key under the chin?
Hot, the human body also emits waves (Wein’s Law). Thus By placing the fold under the chin, it will propagate the waves, relay them, or even amplify them. It is thus a few meters that will be gained, thus allowing to unlock the car. There is therefore no question of magic to explain this phenomenon.
As you can see, you can therefore increase the unlocking distance of a vehicle using your own body. Prudence would dictate that we ask whether this is good or bad. It can be assumed that the waves used in the plip system are not harmful and can be amplified safely. It’s up to you to try the experience or not!
