Protect Your Vehicle from Unauthorised Wireless Communication
Modern keyless entry systems make accessing your vehicle quick and convenient, but they also rely on wireless communication between your key fob and your vehicle. The Leblok Security Key Fob Faraday Bag helps physically isolate your key fob from external radio signals whenever it is correctly sealed, helping to protect against relay attacks, key cloning and accidental vehicle unlocking.
Manufactured in the UK and built for everyday use, the Leblok Security Key Fob Faraday Bag combines high-quality construction with dependable signal isolation. Whether you keep your keys at home, carry them in your pocket or travel regularly, it provides a simple and effective way to prevent your key fob from communicating until you choose to remove it.
Unlike an ordinary key case or pouch, a Faraday Bag creates a physical barrier between your key fob and external wireless signals, helping to prevent communication while the bag remains securely sealed.
Designed for Car Key Fobs
The Key Fob Faraday Bag has been developed to accommodate most vehicle key fobs while remaining compact enough for everyday use.
External Dimensions (Closed):
140 × 120 mm
Suitable for:
-
Most vehicle key fobs
-
Keyless entry remote controls
-
Garage door remote controls
-
Small RFID-enabled devices
-
Other compatible electronic devices
As with any Faraday Bag, effective shielding depends on the bag being correctly sealed using the double-fold closure.

Why Choose Leblok Security?
Shielding is at the core of what Leblok does.
Long before introducing the Leblok Security range, Leblok established itself as a specialist manufacturer of EMF shielding clothing and protective products trusted by customers around the world. The same understanding of RF shielding materials, construction techniques and quality control has been carried directly into every Faraday Bag.
The Leblok Security Key Fob Faraday Bag incorporates a high-performance RF shielding layer together with durable waterproof outer material and reinforced stitching to provide dependable signal isolation and long-term durability.
Every Leblok Security Key Fob Faraday Bag is manufactured in the UK and individually inspected before leaving our factory, because dependable signal isolation relies not only on the shielding material but also on the quality of the finished construction.

Independently Tested Shielding Material
Confidence in shielding performance should be based on independent testing rather than assumptions.
The RF shielding material used in the Leblok Security Key Fob Faraday Bag has been independently tested by the University of the Armed Forces (RF, Microwaves and RADAR Department), Germany, in accordance with internationally recognised standards:
-
ASTM D-4935-10
-
IEEE 299-2006

Frequently Asked Questions
We've answered some of the questions customers most often ask before choosing a Leblok Security Key Fob Faraday Bag. If you need any further information, please don't hesitate to contact us.
The Leblok Security Key Fob Faraday Bag helps physically isolate your key fob from external radio signals when it is correctly sealed.
This prevents normal wireless communication between the key fob and external devices while it remains inside the bag, helping to protect against unauthorised key fob communication, relay attacks and accidental vehicle unlocking.
When the bag is correctly sealed, the key fob is isolated from the vehicle's wireless communication. Your vehicle should therefore not be able to communicate normally with the key fob while it remains inside the bag.
Simply remove the key fob from the bag when you want to use it normally. Once outside the bag, it can communicate with your vehicle again.
Keyless vehicle systems rely on wireless communication between the vehicle and its key fob. A correctly sealed Faraday Bag creates a shielding barrier around the key fob, helping to prevent external radio signals from reaching it.
By physically isolating the key fob when it is not being used, the bag can help reduce the opportunity for unauthorised wireless communication with the key.
The Key Fob Faraday Bag is suitable for most vehicle key fobs and keyless entry remote controls.
External dimensions (closed):
140 × 120 mm
The key fob must fit comfortably inside the bag while still allowing the opening to be folded twice and securely fastened. If the bag cannot be correctly sealed, effective signal isolation cannot be expected.
Place your key fob fully inside the bag, fold the opening over twice and secure the fastening strap firmly.
The double-fold closure is an important part of the shielding system. Make sure the opening is properly folded and secured whenever you want to isolate the key fob.
Yes. The bag can be used whenever you want to keep your key fob physically isolated from external wireless signals.
Many people use a Faraday Bag when storing their vehicle keys at home, particularly when the vehicle is parked close to the house. You can also use it when travelling or whenever you do not need to use the key fob.
When correctly sealed, the bag helps isolate compatible devices from a range of radio-frequency signals, including RFID and other wireless communication signals within its shielding range.
The RF shielding material used in the bag has been independently tested, and detailed test results are provided on this product page abowe.
Once the key fob is removed, it can communicate with the vehicle normally again.
You can therefore keep the key fob isolated while it is not needed and remove it when you want to unlock, lock or start your vehicle, depending on the type of keyless system your vehicle uses.
