RFID and Faraday pouches are often overlooked in the world of car security products, but they can be massively effective in keeping your car secure. They don’t offer the same amount of physical security as a steering wheel lock, but they offer some peace of mind by interrupting the signal that your key fobs emit to unlock and start your vehicle.
While car technology advances it does mean that we can become more vulnerable to alternative methods of theft, and not everyone will have the best intentions. Keyless technology is one of those concepts which makes our lives easier by transmitting a Radio Frequency Identification (RFID) signal to lock, unlock, and start our cars. It may be more convenient than traditional keys, but it’s also more convenient for unscrupulous individuals to gain access to your car by cloning the RFID signal.
A notable problem has been found with Land Rover vehicles, which have been increasingly targeted by criminals in recent years. JLR issued an update to its keyless entry system and came up with its own insurance policy to tackle the epidemic. Despite the efforts of car manufacturers, we recommend you take the necessary steps to reduce the risk by investing in a Faraday box, bag, or pouch. In the grand scheme of thigs it’s a small price to pay for that extra layer of protection to your cherished vehicle.

So, how does it work? A Faraday pouch is a metal mesh inside a bag, pouch or box. The mesh blocks the RFID signals from your key, meaning there is nothing for the would-be thief to clone. The important thing to note is that a Faraday pouch is a proactive measure to prevent your car from being taken in the first place. And if you’re feeling extra conscious, we’ve also made a guide on the best car trackers.

FAQs and what you need to know about RFID and Faraday pouches
What is an RFID and Faraday pouch?
Car security has come a long way since the days of steering wheel locks as keyless tech has moved on. A Faraday pouch is a type of bag made with materials that block electromagnetic radiation. The pouch is designed to protect electronic devices such as key fobs, smartphones and credit cards from being hacked, tracked, or compromised by electromagnetic signals. There are even larger Faraday boxes available for when you’re at home.
How do RFID and Faraday pouches work?
Faraday pouches work by using mesh that blocks electromagnetic signal. When an electronic device is placed inside, its signal is protected from leaving the pouch. This prevents thieves or hackers from accessing the RFID signals coming from the device. Unfortunately, they’re not 100% effective. While they can block a significant number of electromagnetic signals, some may still be able to penetrate the pouch. In addition, the effectiveness of the pouch may be reduced over time as the materials degrade or become damaged. However, a good quality Faraday pouch can provide a high degree of protection.
How can I test my Faraday pouch?
It is actually very simple to test your pouch, and we recommend that you do it often to ensure your pouch is working properly. Simple place your car keys inside the pouch and approach your car. If your car unlocks then it means your pouch is ineffective and needs to be replaced, but if your car doesn’t unlock at the range that it usually would then that means your pouch is offering the protection that you need.
Is it worth getting a Faraday pouch?
RFID and Faraday pouches are a key layer of protection if you don’t fancy physical deterrents such as wheel clamps. If you are concerned about your keyless vehicle’s security, a Faraday pouch can be a good investment. As well as your key fob, a Faraday pouch can protect your credit cards and phone as well. For a relatively small investment, it can give you some peace of mind.
Do Faraday pouches wear out?
Yes, Faraday pouches can wear out over time, especially with extensive use. If your pouch develops holes, or the material starts to wear down, then the signal can find its way through rendering the pouch ineffective. It is important to find a good quality pouch that will last a long time, otherwise you may find yourself having to buy another pouch very soon. You should also make sure that you’re closing your Faraday pouch properly otherwise it won’t do its job of protecting your keys signal.
