Anti-theft Faraday key fob pouch Hurtel Faraday Box 14×10 cm black — radio wave blocking key case

Hurtel Faraday Box is an anti-theft key fob pouch engineered to block radio frequency signals and protect vehicle key fobs from relay attacks and unauthorized access. The soft-lined case measures 14×10 cm and accommodates most modern key fobs, creating an RF-shielding Faraday cage barrier that prevents remote unlocking, signal cloning and unwanted tracking. The compact black design is intended for everyday use at home, during travel, or when leaving keys with valet services.

Advantages

The Hurtel Faraday Box offers passive protection without requiring batteries or configuration, relying on conductive shielding material to attenuate wireless signals. Its 14×10 cm internal dimensions suit a wide range of key fobs while the soft lining reduces scratches and wear. The pouch provides consistent radio wave blocking across common keyless entry and RFID frequencies, delivering a simple physical layer of security for vehicle access devices.

Suitable for

• Protecting vehicle key fobs from relay theft and remote unlocking
• Storing spare keys at home to prevent signal interception
• Secure transport of keys during travel
• Leaving keys with valet services or parking attendants

Key specifications

• Internal size: 14 × 10 cm
• Material: conductive RF-shielding layers with soft inner lining
• Color: black
• Function: blocks radio frequency signals used by keyless entry and RFID-based devices
• Power: passive (no batteries required)

How to use

Insert the vehicle key fob into the pouch and fully close the opening so the fob is enclosed within the shielding layers. Keep the pouch closed whenever the key is not in active use to ensure radio signals are blocked. The pouch can be carried in a bag, placed on a tabletop at home, or handed to a valet with the key securely enclosed. Periodically inspect the lining and closure for wear to maintain optimal blocking performance.

Usage recommendations

For best results, always place the key fob centrally inside the pouch and ensure the closure is fully sealed. Avoid folding or creasing the shielding layers unnecessarily, and keep the pouch away from sharp objects that may pierce the material. If you rely on passive blocking for long-term storage of spare keys, test the pouch with your specific key fob to confirm signal attenuation before leaving the keys unattended.
