Dyzi RFID Faraday Box for Car Keys Signal Blocking Case - Black

An RFID Faraday box works by creating a barrier that blocks radio frequency signals. The double-layer signal-blocking fabric inside the box effectively prevents signals from entering or exiting, thus protecting your contactless items from unauthorized scanning or relay attacks.

This box is specifically designed to protect against keyless entry theft, which involves signal relay attacks. It blocks the radio frequency signals emitted by your key fob. It does not protect against physical theft of the car or the key fob itself if it is stolen by other means.

The Dyzi RFID Faraday Box has space to store up to four car key fobs.

Yes, the box can be used to protect contactless credit cards, debit cards, and any other cards that utilize RFID technology.

The exterior features a carbon fibre-textured finish combined with a PU leather finish, providing a stylish look and durable feel. It is not solid carbon fibre.

No, the Dyzi RFID Faraday Box does not require any power source, batteries, or charging. Its protective function relies solely on the properties of its signal-blocking fabric.

To clean the interior, gently use a dry cloth to remove any dust or debris. Avoid using liquids or harsh cleaning agents, as these could damage the signal-blocking fabric.

Ensure the lid of the Faraday box is completely closed. Verify that the items are placed fully within the shielded interior and not touching the edges of the open lid.

Wipe the exterior with a soft, slightly damp cloth. For stubborn marks, use a mild soap solution and then wipe clean with a damp cloth. Ensure it is completely dry before use.

The box is designed to hold up to four key fobs. Larger items or multiple items may prevent the lid from closing properly, compromising the signal-blocking effect. Try storing fewer items.
