• Beware! Your hi-tech car can be stolen
• Why is it necessary to wrap the key in aluminum foil for security?

Aluminum Foil For Car Keys: Although modern technology has made human life easier, new threats are also emerging with it. Nowadays, car theft methods have become more hi-tech and ‘smarter’ than ever before. In the past, thieves used to steal cars by breaking the door or glass, but now cars are disappearing in a flash without leaving any trace. There has been a huge increase in the number of car theft cases globally, and car owners are now using household items like aluminum foil to avoid this. Although this trick looks strange, it is considered to be very effective.

‘Key-less’ Entry System: Convenience or Headache?

Nowadays most of the new and expensive cars are provided with ‘Keyless Entry’ system. In this, the car door automatically opens when the key is in the pocket. This system works through a wireless signal between the car and the ‘key-fob’. However, this facility is now becoming a big opportunity for thieves. Thieves are easily opening car locks by interfering with these wireless signals.

What is a ‘Relay Attack’?

At present, ‘Relay Attack’ is the most used technique for car theft. Usually two thieves work together. One thief stands near the car, while the other goes to the door or window of the house where the car key is kept. With the help of a special electronic device, they capture the key signal (Boost) and transmit it to the car. The car senses that the key is nearby and unlocks instantly. Shockingly, burglars can also pull the signal of a key inside the house from outside.

Reality revealed by research

According to various media reports and technical research, these wireless signals can travel several feet. Especially if your key is behind the main door of the house or near a window, thieves can pick up this signal even when there is no ‘line of sight’. This means that while your keys are safe inside the house, your car is not safe outside.

The ‘smart’ trick of aluminum foil

Many experts are now recommending the use of aluminum foil to avoid this technical theft. When you wrap a car key in aluminum foil, it acts as a kind of shield. This foil blocks the electromagnetic signals emanating from the key, making it impossible for thieves’ devices to pick up these signals.

Expert tips to keep your car safe:

• Aluminum foil: Keep the key wrapped in foil when at home.
• Faraday Pouch: You can use special ‘Faraday pouches’ available in the market, which are designed to block signals.
• Replace key: Never keep the car key near the main door or window of the house. Keep it in the middle of the house or in a safe place.
• Software Update: Always keep your car security system updated.

Your vigilance and these small changes can save your car worth millions of rupees from theft.
