Keep your car safe from keyless theft with Faraday protection

Block your key fob's signal and help stop thieves from using relay attacks to unlock your car. Simple protection for your keys, wherever you go.

How a relay attack works

Keyless cars listen for their key fob's signal. Thieves can exploit that.

  1. A device picks up your fob's signal

    Standing near your home, a thief uses a device to catch the signal your fob gives off, even through walls.

  2. A second device passes it on

    The signal is relayed to a partner standing next to your car.

  3. The car thinks your key is nearby

    It unlocks and may start, without anyone touching your real key.

A Faraday pouch or box blocks the fob's signal while the key is inside, which helps reduce your exposure to this kind of attack.

Honest about limits

It helps reduce the risk of relay attacks but can't prevent every type of vehicle theft.

Common questions

Will it work with my car?

It's made for keyless-entry and push-button-start fobs. Cars and fobs differ, so run the test above with your own key.

Will my fob fit?

Each pouch is 3.1 × 5.1 inches, which fits most standard fobs. Bulky fobs may not fit, so measure yours first.

Should I keep my key in it all the time?

It's most useful when you're not using the key, such as overnight. Take the fob out when you want to unlock or start your car.

Can I put my phone in it?

It's designed for key fobs and cards, not phones.

Does it stop all car theft?

No. It helps reduce relay attacks, but it won't stop other methods or protect a fob that is outside the pouch or box.

Don't give thieves an easy signal

Protect your key. Reduce your exposure to relay attacks. Drive with greater peace of mind.
