OMKHE Faraday Box for Car Keys — Large Black RFID & Key-Fob Protector with Double-Layer Shielding

The OMKHE Faraday Box for Car Keys is a signal-blocking protective case that stops RFID, Bluetooth, GPS and key-fob relay attacks by creating a secure Faraday enclosure for keys, cards and small electronics.

If you own a keyless vehicle, travel with contactless cards, or want to stop unwanted wireless scanning, this compact Faraday box provides a practical, everyday layer of privacy and theft-prevention. Built with double-layer shielding, hand-sewn seams, and a rigid shell, the OMKHE Faraday Box works as a simple physical barrier to block signals from 10 kHz up to 30 GHz and reduce signal strength by up to 90 dB. It pairs protection with refined materials — protein leather, soft flocking, and a metal buckle — so security looks and feels premium on a shelf, in a drawer, or inside a travel bag.

How does the OMKHE Faraday Box stop car key relay attacks?

Relay attacks rely on amplifying or rebroadcasting your key fob’s signal to open and start a vehicle. The OMKHE Faraday Box prevents that by enclosing the fob within conductive layers that dissipate and reflect incoming and outgoing radio frequencies.

• Double-layer high-density Faraday shielding blocks Wi‑Fi, Bluetooth, NFC, RFID and car fob frequencies.
• Seams are hand-sewn and casing is 360° seamless for continuous shielding.
• Rated to shield signals from 10 kHz up to 30 GHz with up to 90 dB attenuation.

Will it hold more than a single key fob — what fits inside?

The box is sized for flexibility: use it for multiple car keys, passports, credit cards and small smartphones (Large size recommended for phones). The interior soft flocking protects finishes while the rigid exterior keeps shape and shielding performance intact.

• Stores multiple key fobs, contactless cards, passports and small phones (Large size suggested for phones).
• Includes a matching Faraday bag for double-layer protection or on-the-go use.
• Interior padding prevents scratches and helps organize small items.

How durable and stylish is this Faraday box for everyday use?

OMKHE balances protection with refined materials: protein leather, thickened metal reinforcement plates, and a vintage-style buckle provide a long-lasting, upscale appearance suitable for home, office or travel. Available colors and sizes let you match personal style without sacrificing function.

• Protein leather exterior with soft inner flocking for a premium look and feel.
• Thickened high-strength plates and a durable metal buckle for lasting use.
• Offered in multiple colors and two sizes to fit different storage needs.

How do I use the included Faraday bag and box together?

The box includes a same-color Faraday bag with key chain and hook so you can carry a shielded pouch while leaving the rigid box at home for extra security. Use the bag alone for quick trips, or place the bag inside the box for redundant blocking when traveling or storing multiple items.

• Carry the lightweight Faraday bag clipped to keys or a bag for daily signal blocking.
• Drop the bag inside the box for double shielding at home or on trips.
• Key chain and hook add convenience and portability for active use.

Who is this for: The OMKHE Faraday Box is ideal for owners of keyless-entry cars who want a simple physical defense against relay attacks, travelers who use contactless cards and passports, and anyone who values low-effort privacy for small electronics. Choose the Large size if you plan to include a smartphone; otherwise the standard size covers multiple fobs and cards. If you have questions about color availability or sizing, OMKHE provides customer support to help match the right option to your needs.
