Modern keyless cars are convenient, but the same wireless key fob that unlocks your car when you walk up can be exploited. In a relay attack, thieves use a pair of devices to capture the fob's signal from inside your home and relay it to the car, so the car thinks the key is nearby. It can happen in seconds and often in total silence.
What a Faraday pouch does
A Faraday pouch (or box) is lined with signal-blocking material. When your key fob is inside it, the fob's signal can't be captured. It is cheap, takes no installation, and is one of the easiest steps you can take. Test yours: put the fob inside, close it fully, then stand next to the car. If the car still unlocks, the pouch is not blocking properly.
Layer your protection
No single device stops every theft. Thieves tend to move on to an easier target, so the goal is to add friction:
- Signal blocking: store fobs in a Faraday pouch or box at home, away from doors and windows.
- Visible deterrents: a steering wheel lock or brake lock tells a thief the job will take longer.
- Immobilizer-style devices: add a second hurdle that stops the engine starting without extra authentication.
- Tracking: a hidden GPS tracker can help recovery. Check that any tracker you buy works on your local cellular network.
- Parking: park in a garage or well-lit spot where you can, and keep the car in view of a camera if possible.
Ask your insurer
Some insurers offer discounts for approved anti-theft equipment, but not every device qualifies. Call your insurer before you buy so you know which devices count.
