Car theft is getting smarter. So should your key protection.
Our Signal Blocking Faraday Box is designed to help block wireless signals like RFID, NFC, Bluetooth, and 5G - reducing the risk of relay attacks used in modern keyless entry theft.
🚗 Why You Need Our Signal Blocking Faraday Box For Your Car Keys: Modern car theft is fast and silent. Thieves now use relay technology to capture your key fob signal from outside your home, unlocking and starting your car in as little as under 60 seconds without ever entering your house. The Totyn™ Faraday Box helps block those signals, giving you peace of mind while you sleep.




Q: How Does The Signal Blocking Box Work To Help Protect Me?
A: The box is lined with Faraday fabric that helps shield wireless signals like RFID, NFC,Bluetooth and 5G. When your key fob is inside with the lid closed, it reduces the risk of relay attacks and unauthorised signal capture.
Q: What Is The Box Made From?
A: The outside is premium PU vegan leather, and the inside is a layered RFID-blocking fabric. It’s durable, lightweight and ideal for daily household use.
Q: Should I Store Spare Keys In The Box Too?
A: Yes - spare keys are just as vulnerable. Keeping all fobs inside the box adds a layer of protection against theft from outside your home.
Q: What Fits Inside?
A: The size is 21×13 ×7cm (8.3"× 5.1"×2.8"), large enough for 5–6 car keys, a smartphone, or tap-and-go cards.
Q: Can It Block Phones Or Credit Cards Too?
A: Yes. It’s designed to block signals from phones, smart devices and RFID-enabled cards. It can also help reduce exposure to EMF while you sleep.
Q: How Do I Test If It's Working?
A: Place your key inside, close the lid fully, and try unlocking or starting your car. If it doesn't respond, the box is working. Test regularly to ensure continued performance.
Q: What Signals Does It Help Block?
A: It’s designed to help shield RFID, Bluetooth, Wi-Fi, NFC, GPS, and mobile (3G/4G/5G) signals. This reduces the risk of relay-style keyless theft and digital snooping.
Important Usage Information
Important Usage Information
The Totyn™ Faraday Range is designed to help block wireless signals - including RFID, NFC, Bluetooth, and 5G - when your car key is fully enclosed in the signal-blocking compartment. Correct usage is essential for optimal performance.
To Use:
- Place your key fob into the inner, signal-blocking layer (usually the rear pocket) or into the box.
- Ensure the pouch or box is fully closed, with the flap sealed.
- Regularly test the pouch/box by attempting to unlock or start your car while the key is inside.
Do Not:
- Leave the flap/box open.
- Store keys in the front pocket (it does not block signals).
- Assume the pouch/box is effective if used incorrectly or damaged.
This product is designed to reduce the risk of keyless entry theft by helping block wireless signals. It must be used properly and kept closed to be effective.
No signal-blocking pouch can guarantee 100% protection from relay attacks or keyless entry theft. Factors such as wear, physical damage, or improper use may affect performance.
Use at your own discretion. Totyn™ and its affiliated brands are not liable for any loss, theft, or damage resulting from misuse or product failure.
