In the age of keyless car technology, the threat of vehicle theft has escalated with criminals now able to hack your keyfob signal to steal your motor. But savvy shoppers have found a budget friendly way to secure their cars by using specially designed signal blocker pouches and boxes.

These handy devices can keep your keys shielded at home or while you’re out, ensuring thieves can’t pilfer your ride. Amazon’s current deal features the highly-rated Todoxi Faraday Box and 2 Pack Faraday Pouch for just £18.69 in a limited time early Black Friday deal, reports the Express.

This combo set includes a stylish black leather box and two pouches, with capacity for about nine to twelve keys, allowing you to safeguard spare house keys as well.

Satisfied users are praising the product, with one reviewer sharing: “Does what it says on the tin. Complete protection and signal blocking for wireless keys, preventing car unlocking even with the box pressed against the car door. Inoffensive to look at, easy to operate, spacious enough for a handful of keys. Excellent value.”

One customer was impressed with the effectiveness of the kit, saying: “I had read about cars being stolen due to thieves amplifying the signal from the key fob and hacking it in some way. This product works a treat and completely blocks the signal. The box has plenty of space and is ideal for home use and the pouches are handy when travelling. The only inconvenience is when you have keyless entry you have to take the fob out of the pouch but for me that’s a minor inconvenience which is far outweighed by the extra security offered.”

Another added: “The box is a great size, doesn’t take up too much space but houses a few sets of keys. The 2 additional wallets are great, clearly bulkier than just having the key but when the key is in the wallet the remote access doesn’t work. Really good product.”

However, some customers pointed out potential drawbacks. One noted: “Liked that it worked, would have preferred it to be a little deeper to ensure my ‘key’ would be fully enclosed.”

Meanwhile another faced challenges with the design, ironically describing it as potentially too secure: “To say that the lid is a bit tight is an understatement. You have to pick it up in both hands to prise it open.”

For those looking for alternatives, Halfords offers the Anti-Theft Car Key Signal Blocker – Black for £6, which provides a single pouch solution, whereas Argos sells the Streetwize Car Key Signal Blocking Faraday Box – Black for £20, which includes just the box without any additional pouches.
