No, we haven’t gone crazy: Someone started putting their car keys in the microwave. What is it for? Let’s see why you should do this.
Keys in the microwave – Motori.news
The latest generation cars they are all equipped with ultra-modern keys that are certainly very different from those we once knew.
In addition to having the integrated remote control with which to open and close the doors even from a distance, the more technological ones are even… without a key, in the sense that just have them with you to ensure that cars recognize them, allowing us to start the car without inserting them in the ignition switch.
Indeed, in many modern cars this block is no longer even present, replaced by a start button usually installed in machines equipped with the start and stop system.
So super technological and very intelligent keys that allow the driver to unlock the door and start the car simply keeping them in your pocket. Merit of sensors inserted in the body of the car that are able to detect their presence even from a distance.
The problem is that such a technology can become also a friend of thieves which, with suitable signal repeaters, can carry out the car theft very easily.
If it sounds like science fiction to you, it’s actually a true story from the UK. His wife tells us about it Edmund Kingpresident of the Automobile Association, who explained that their approximately 60,000 euro Lexus literally disappeared in the middle of the night without anyone noticing.
The hypothesis is that they have exploited the technological key system and, through a series of repeaters, the thieves managed to steal the car and do with it what they wanted. The advice that to prevent such cases? There’s a microwave oven.
Why put your car keys in the microwave
An important detail must be added to this episode: the key which was in the house, and evidently still within the detection range of the Lexus, was hidden inside a metal boxwhich however was not sufficient to block the transmission of radio signals.
Edmund King then decided to enhance this protection system: the key was placed in a metal mesh bag, which was in turn hidden in the box which was finally placed inside the microwave oven.
In this way, King explains, the operation of the microwave acts as a Faraday cage it prevents the radio waves from the keys from being transmitted to the car, thus preventing theft also through sophisticated signal repetition and transmission systems.
Just to be safe, King decided to add a steering wheel lock systemso as to avoid possible trouble.
In short, if your car is also equipped with such a system, when you are at home consider keeping the key in the microwave. But remember not to turn it on with the remote control still inside…
