Faraday Bag for Key Fobs | Blocks Relay Attacks | SHIELDSAK

Relay attacks can clone your key fob signal in seconds, even through your walls. Thieves use $30 amplifiers to grab your key's signal from inside your home and drive away with your car. The SHIELDSAK Key Fob Pouch stops the signal cold with patented Faraday cage fabric that blocks RF, RFID, and infrared frequencies instantly.

• Blocks RF, RFID, and infrared frequencies
• Prevents relay attacks and keyless entry theft
• Works with all keyless entry fobs, any make, any model
• Also protects credit cards from RFID skimming
• Patented soft Faraday fabric construction
• Made in the USA

Perfect for: Any keyless entry vehicle, credit card protection, smart card security.

Built to back up the claim. SHIELDSAK is made from ripstop nylon with silver, copper, and nickel woven directly into the fabric. An independent lab called Keystone Compliance tested it from 30 MHz to 18 GHz and confirmed up to 104 dB of signal blocking. That is a real test result, not a marketing claim.

Self-test: Place your fob inside and try to unlock your car from the usual distance. The door should not respond. If it does, return it for a full refund with no questions asked.
