Mission Darkness Faraday Bag for Key Fobs - prevent "relay attacks" on keyless entry vehicles
The Mission Darkness Faraday Bag for Key Fobs is a high quality Faraday bag designed to keep vehicles secure by blocking the fob’s signal from communicating with the vehicle. Built with a durable and water-resistant ballistic nylon outer material, and three layers of high-shielding TitanRF™ Faraday Fabric on all interior sides with dual paired seam construction.
The Faraday bag works by shielding “always-on” key fobs and other small electronics (like smart watches, transmitters, and credit cards) from radio frequency signals, ensuring that the device cannot get hacked and the signal it constantly emits cannot be boosted. The bag should be used as a preventative measure for vehicle and data security. The bag also allows you to keep a spare key fob isolated and locked inside your vehicle.
Prevent Relay Attacks & Vehicle Theft: The bag prevents thieves from detecting or cloning your fob signal. Hackers use amplifiers to boost your key fob’s signal from inside your home, opening your car. This bag acts as a shield to sever that connection.
Designed For: vehicle security, forensics, military, executive travel, data privacy, and personal security. Also suitable for shielding smart watches, and credit, building access and ID cards. Prevents advertisers, apps, or malicious actors from tracking the constant signal emissions of smart watches or RFID-chipped cards.
Simple to Use: Simply place fob or card inside the bag, fold the top over and tuck under elastic band for instant signal isolation. Device signals cannot penetrate the bag while properly enclosed inside.
Serialised: Each bag has a unique serial number for asset tracking and evidence chain-of-custody documentation.
Two-Pack: Two Faraday bags included in each set
Construction:
- The exterior is constructed of water-resistant Ballistic nylon

Vehicle Theft Prevention
Stops thieves from using signal-boosting devices to capture and amplify your key fob's code, which is otherwise used to unlock and start your car without a physical key.
Spare Key Isolation
Allows you to leave a spare active key fob inside your vehicle (such as in the glovebox) without the car recognizing the fob's signal, preventing the vehicle from being easily unlocked or driven off.
Outdoor Activity Convenience
Perfect for people who want to lock their car but keep their active key fob on their person without the risk of the car unlocking due to proximity.
Everyday EMF and Tracking Defense
Prevents advertisers, apps, or malicious actors from tracking the constant signal emissions of smart watches or RFID-chipped cards.
Law Enforcement & Forensics
Used by officers to secure confiscated key fobs or small wireless devices immediately, ensuring no data can be remotely altered, accessed, or wiped before formal analysis.
