The lockOZ Signal Blocking Faraday Box for your car keys stops this by shielding your key fobs from wireless signal interception.

Relay attacks is among the fastest growing theft in the country. They amplify your key's signal to unlock your car remotely — unlocking and starting your vehicle in under 60 seconds without ever touching your keys.

How it works: Place your key fobs inside the box, close the lid firm. All wireless signals are blocked. Your keys stay protected—so does your car.

Key Features:

  • Premium double-layer Faraday fabric – Engineered to block RFID, NFC, Bluetooth, Wi-Fi, GPS, and cellular signals (3G/4G/5G), helping prevent relay attacks when keys are fully enclosed
  • Large capacity storage – Comfortably Holds up to 4–12 sets of car keys (depends on size), phones, contactless cards, and other small valuables
  • Tested signal blocking – Every box is tested to ensure 100% signal blocking when properly closed
  • Minimalist designed vegan leather exterior – Available in three finishes: charcoal, honey brown, and slate grey. Premium PU leather with crazy horse texture complements any room or console table
  • Durable construction – Military-grade fabrics and reinforced design for long-lasting protection
  • Universal compatibility – Works with all keyless car keys, RFID-enabled cards, and NFC devices
  • Protects spare keys too – Don't leave backup fobs vulnerable. Store all your keys in one secure location
  • Radiation shielding – Helps block micro radiation and electromagnetic fields from phones and other devices for a calm and peaceful night

Important Usage Notes:

  • Ensure the lid is fully closed and clasped for complete signal protection
  • Test effectiveness every 6–8 months: Place your key fob inside, close the box, and try to unlock or start your car (signal should be blocked). Faraday fabric may naturally loosen over time—regular testing ensures continued effectiveness
  • Keep all key fobs (including spares) stored inside when not in use
  • Clean exterior with a damp cloth. Do not machine wash—this can damage the internal Faraday fabric and weaken signal-blocking properties

Stop relay attacks before they happen. The lockOZ Signal Blocking Faraday Box gives you simple, effective protection for your entire family's keys—in one stylish, secure place.

Note: This product is designed to greatly reduce the risk of relay-style car theft, not to guarantee prevention. Always ensure the lid is fully closed for maximum protection. lockOZ is not liable for any theft, loss, or damage.
