Hurtel Faraday Box anti-theft key and phone signal blocker — Faraday cage, black

Hurtel Faraday Box is a compact anti-theft enclosure designed to block radio signals to car keys and mobile phones. The black Faraday cage isolates stored items from RFID, Bluetooth, Wi‑Fi and mobile networks, preventing remote unlocking, relay attacks and unwanted communication while devices or keys are not in use. The box is intended for everyday storage at home, in the office or while travelling and provides a simple physical method to reduce the risk of electronic interception.

Advantages

The Hurtel Faraday Box offers signal-blocking protection in a discreet black housing that fits standard car keys, key fobs and most smartphones. Its passive design requires no power or software updates and works continuously whenever items are placed inside. The rigid enclosure provides an additional layer of physical protection against accidental activation of buttons and limits wireless tracking and unauthorized access attempts.

Suitable for

• Storing car keys and key fobs to prevent relay theft
• Keeping mobile phones isolated from calls, messages and data networks during meetings or travel
• Protecting RFID-enabled cards or devices from unauthorized reads
• Secure temporary storage of small electronic items at home or in the office

Key specifications

• Function: passive radio-frequency signal shielding (Faraday cage)
• Blocked signals: RFID, Bluetooth, Wi‑Fi, GSM/3G/4G/5G mobile networks
• Housing colour: black
• Form factor: compact box suitable for keys and most smartphones
• Power: none required (passive operation)

How to use

Place the keys, key fob, phone or other small electronic item inside the Hurtel Faraday Box and close the lid fully to ensure complete isolation from external radio signals. No setup or power source is required; the enclosure provides shielding as long as the lid remains closed. Before leaving a vehicle or storing items for a prolonged period, confirm that the item is inside the box to prevent accidental signal transmission or location tracking.

Usage recommendations

Use the Faraday box in a dry environment and avoid placing wet or damaged devices inside the enclosure. For consistent signal blocking, ensure the lid is completely closed and that the edges form a continuous barrier. When storing multiple items, arrange them so the lid closes securely and check that large metal objects are not placed against the shielding surface, which could affect fit but not the blocking function.
