Keyless entry provides a convenient, hands-free way to enter your vehicle. With the smart/intelligent key fob on your person, you simply have to put your hand on the door handle and it will sense this and unlock. This, however, poses a security risk.

In 2017, the Office for National Statistics reported that 89,000 vehicles were stolen, which increased by 56 per cent from the year before. These figures revealed that 2017 was the worst year for car thefts since 2012.

How the “Keyless” Theft Happens

Thieves use a relay amplifier and transmitter. These can receive signals through walls, doors or windows. The relay essentially amplifies the signal that your key fob generates, collects it and sends it to your vehicle. This tricks your car into thinking the key fob is next to the vehicle, allowing the thieves to get in and well, get out.

Steps You Can Take to Prevent Car Theft

While you could wrap your key fob in aluminium foil, or place it in a microwave, an anti-theft pouch is a much better solution. The relay devices used by car thieves can receive signals through walls, doors and windows, they can’t handle metal.

Here are some options to help keep your car safe:

  1. parking your vehicle in a garage
  2. using outdoor CCTV cameras/motion sensors
  3. RFID Signal Blocking Pouch













Where you place your key fob is also important. Store them in a safe place, like an Anti-theft RFID signal blocking pouch.


These simple pouches are made of two layers of high quality shielding material, and will block most kinds of wireless signals, such as WIFI/GSM/LTE/NFC/RFI. This also doubles as safe storage for your credit cards and smartphone to prevent unwanted information leakage.
