Faraday Key Fob Bag — RFID Signal Blocker (Anti-Theft)

Car thieves don't need your keys anymore — they amplify the signal from your fob through your front door and drive away. A $9 Faraday bag stops this attack cold. Drop your keys in when you get home, your fob is invisible until you take it out.

Why this matters now

Relay-attack theft has exploded since 2020. Thieves with a $30 amplifier stand near your front door, capture your key fob's signal through the wall, and relay it to your car parked in the driveway. The car thinks the key is right next to it and unlocks. No broken window, no alarm, no trace — just a missing car in the morning.

It works on virtually every modern keyless-entry car. The only defense: put your keys in something that blocks the signal.

What you get

• Double-layer Faraday shielding — blocks signal in every direction
• Carbon fiber exterior — durable, looks sharp
• Holds 2-3 key fobs — enough for both household keys
• Fits in a pocket or by the front door
• Tested signal blocking — your keyfob will not unlock your car when it's inside the bag (try it!)

How to test it works

Put your fob in the bag, walk up to your car, press unlock through the bag. Nothing should happen. That's the point — if your fob can't unlock your car from 6 inches away, a thief can't amplify the signal from 30 feet away either.
