Here at Supra UK we understand the importance of having a reliable solution to ensure your car key is secure and protected against crime. After all, over 100,000 car keys across the UK and Europe in the automotive industry rely on our attention to detail!

To achieve our high standard in shielding not only have we developed a fabric consisting of high performance flexible metals, hand stitched in metal thread but we have built-in a metallic hook-and-loop fastener for quick access whilst maintaining a strong reliable shield. It's also sized so that it works on your NFC (contactless) credit or debit card.

At The Key Safe Company, we're constantly trying to pair the latest technology with old-school reliability. This faraday bag gives you the benefits of keyless go, without the risks.

View Full Overview

As more technology is added into modern vehicles, car key signal amplification is a growing method of allowing criminals to access and steal vehicles and their contents.

The Car Key Shield blocks the communication between your key and car, giving you security and peace of mind.

How does it work?
Modern car keys often come equipped with keyless entry. While this is useful when you have your hands full with shopping or children, the signal that allows your car to open conveniently can be extended, copied, or simply used to remotely start your vehicle from outside your home. The Car Key Shield is made from a weave of silver, copper and nickel, which blocks out electromagnetic frequencies known as a Faraday shield.  This shield acts as a barrier for your keys’ signal, meaning the vehicle cannot communicate with the vehicle’s ECU to unlock or start the car. 

We’ve tested the Car Key Shield extensively, and determined an excellent effectiveness at blocking signal, even when using the strongest signal car keys on the market. With an average shielding effectiveness of -85dB in the 30MHz-1GHz range, and -80dB in the 1GHz-11GHz range, this pouch is effective 99.9% of the time.

Because the dual layer shield construction is effective on most wireless signal, not just RFID, this shield can also effectively block;

- NFC Contactless bank cards
- Bluetooth devices
- GPS Tracking
- 802.11a/b/g/n WLAN/WiFi
- 3G, 4G, LTE, Cellular

The bag is 105x85mm, which is more than capable of holding most car keys, along with a keyring or two.

It will happily fit a contactless bank card, and if you require something a little larger for phones or tablets, just let us know!
