What a car key box does

A car key box is an anti-theft cage that blocks RFID (Radio-frequency identification) and electromagnetic fields. Some also call it a faraday key holder and is extremely useful for protecting your vehicle. The box has a metal lining which is responsible for stopping the radio wave signals from spreading and keeps your car protected.

We all want to have a pleasant dinner with our family or have fun with our friends in the evening, but nobody wants extra stress instead of being happy. The problem is neither time management nor money. The biggest challenge here is security. To be more precise, security of our vehicles. Imagine you are having an amazing time with your loved ones at night, suddenly you look through the window but can’t locate your car. This is exactly what happens in most cases. Thieves hack your key fob, steal your vehicle and drive it away without leaving any signs.

Do you think that you want to try creating your very own car keys safe? Fortunately, you can easily make it by combining a box, a metal lining and tin foil. However, the actual product is so cheap (the price is usually around $15) that there is no point in making a new one and wasting your precious time.

What is a relay attack?

Relay attack is copying the signal from your key fob and stealing your vehicles using a cheap device. Hackers take advantage of cars’ new features and break in to a car with a simple signal extender. As technologies are developing every manufacturer tries to make their products more appealing to the customers. Hence, they are adding new features to increase comfort and make your drive even more amusing.

The new technology that is widely used nowadays is Keyless Go. It combines keyless entry (remote entry blogpost) as well as keyless ignition functions. A keyless entry system helps you unlock the whole vehicle by touching the special button on the door. The specifications may vary from one car manufacturer to another. In some cars, you can activate the remote entry system with a single touch on the sensor. It is on the door handle, while others may have a button near the door.

The most important part of the keyless entry system is that you can open your lovely car without even touching or holding your key fob in your hands. On the other hand, Keyless ignition is responsible for starting an engine without placing a key fob. All you need to make both functions workable is to have your key fob in a pocket and stay in range.

Without a car key signal blocking box as much as it sounds fun and relaxing, it also possesses risks. New cars are easy targets for thieves. Two or more people use the tool – key fob signal amplifier (signal amplifier blogpost link). It consists of two parts, one extends the signal range, while another receives the radio magnetic waves.

So, relay theft requires at least two people. One person tries to stand near your key fob to receive the signal from your keys, then extends it with an amplifier. While the other hacker stands next to your vehicle with the device (receiver) in his hands waiting for the signal. As soon as he receives the proper signal, they can unlock the car and even drive it away. This whole process happens within 10 seconds. So, you don’t have enough time to react and before you realize it, your car is already stolen.

What are the advantages of a car key box?

  • Lock – even though every box has its unique locking system, most of them use a 4-digit code that has 10 000 possible answers.

In the case of the key holder, it is not a big issue. as the prices of a box start from as low as $20 and vary depending on the design, manufacturer and the mechanism. If you consider the fact, that even this lock can be easily cracked or physically smashed by a completely beginner thief, maybe even $20 sounds little bit too expensive.
  • Variety – one of the top characteristics of the car key boxes is its variety. There are all types of protection safes available to meet your taste. You will find standing, safe shape or wall mounted versions. You can choose the one that meets your expectations the most. However, if the lock can’t do its one and the only function – to protect the object, variety of the product doesn’t make it worthy of any amount.
