The #1 Trusted Security Measure for Preventing Keyfob Signal Amplification

Malicious vehicle entry using key fob signal boosting methods is the leading threat in the automotive community. Criminals are using signal amplification devices to boost or mimic a key fob’s signal to gain access to automobiles without any forceful entry. The Mission Darkness™ Keyfob Shield is a high quality Faraday bag designed to keep vehicles secure by blocking the fob’s signal from communicating with the vehicle. It’s built with a durable and water-resistant ballistic nylon outer material, and the interior includes three layers of high-shielding TitanRF™ Faraday Fabric on all sides with dual paired seam construction.

The Faraday bag works by shielding “always-on” key fobs and other small electronics (like Apple Watch, 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. The advanced signal blocking bag is commonly used for vehicle security, forensics, military, executive travel, data privacy, and personal security. The capacity is large enough to fit two fobs, or an average set of keys with accessories. The key fob should remain inside of the Faraday bag at all times (when not in use) to ensure your vehicle security.
