Dyzi Faraday Key Box - Black - 2 Pouches

A Faraday box or pouch works by creating a barrier that blocks wireless radio frequencies. When your key fob is placed inside and the enclosure is sealed, it prevents the fob's signal from being intercepted or amplified by thieves attempting a relay attack.

A relay attack is a method used by thieves to steal keyless entry vehicles. They use devices to capture and relay the signal from your key fob (even if it's inside your home) to the car, making the car think the key is present and allowing it to be unlocked and started.

No, the Dyzi Faraday Key Box and pouches do not require any batteries or charging. They function passively by blocking radio signals through their material construction.

While primarily designed for car keys and fobs, you could store other small electronic devices that you wish to shield from external signals. However, ensure they fit completely within the enclosure and do not prevent a proper seal.

Each pouch is designed to hold at least one standard car key fob. Depending on the size of your key fob, you may be able to fit a second one, but it's crucial that the pouch can be fully closed to ensure effective signal blocking.

The product description indicates the box and pouches are compact and lightweight, designed to fit easily on a table, in a drawer, or in a bag. Specific dimensions are not provided but emphasize portability and discreet storage.

Ensure the key fob is placed completely inside the Faraday box or pouch and that the enclosure is fully sealed. Check for any damage to the material that might compromise the signal barrier. Try placing the key fob in a different pouch or the box.

Verify that the box or pouch is not being overloaded with multiple electronic devices that could interfere or that the key fob is not partially exposed. Ensure the closure mechanism is fully engaged.

Gently wipe the exterior with a slightly damp, soft cloth. Allow it to air dry completely before use.
