How To Protect Your Fob Key From Being Wirelessly Tapped

Can a fob key be wirelessly tapped? The answer is yes. If this happens, thieves can open your car door and start the ignition without ever setting off the alarm.

How a Fob or Transponder Key Works

The fob or fob key is a security hardware device that generates an access code every 30 or 60 seconds.

Transponders emit a serial number on a low-level signal. The receiver in the car must detect the correct serial number to unlock or start the engine.

Fobs and transponders have a limited distance in which they can open doors and start the engine.

Here's How Thieves Exploit This Technology

Because fobs and transponders have a limited range, the thieves use a piece of equipment called a power amplifier or signal booster.

One of the thieves positions a signal booster by a window or close to a wall, at a home or office, to pick up a fob's signal. The amplified signal is then relayed to a transponder receiver, which is held by the other thief while he continuously operates the door handle.

Once the door opens, the thief gets in and can start the engine because the car recognized the correct fob key code.

How To Protect Your Keys

Make your key catchall a tin or aluminum container. Also, fob key signal-blocking Faraday cases and pouches are available like the ones sold by TICONN .
Secure spare keys by also storing them in a tin or aluminum container or the Faraday pouches.
Look in your car manual or contact the manufacturer to see if your car fob can be turned off by pressing a button or series of buttons on the fob.
