The Defender Signal Blocker is a high-quality, police accredited faraday pouch, that combats car theft and distracted driving.
The dual-purpose nature of the Signal Blocker sees it combat two of the biggest security and safety issues: relay attacks on vehicle fobs and distracted driving caused by mobile phone use.
Store car key fobs in the faraday pouch and seal, instantly stopping the transmission of the signal from the car key, preventing thieves from being able to ‘boost’ it.
Similarly, a sealed mobile phone cannot receive any calls or notifications, leaving a driver free to focus on the road, free of distractions. Once removed, all missed alerts pull through to the phone within 5 seconds.
The reinforced double stitching technique ensures maximum performance.
The Defender Signal Blocker features a handy external hook to attach to key rings or lanyards.
Best selling ‘faraday bag’ available, winning awards for its exceptional quality and performance, as well as achieving the coveted title of Police Accredited via the Secured by Design Police Preferred Specification.
Beware of imitations! The Defender Signal Blocker is the only blocking pouch to feature industry-leading RPF™ material.

Why not check out the Defender Signal Blocker Mini?
Exactly as stated. Hopefully protects the car from would-be thieves!
Just the job!
Excellent product and speedy delivery
After being the victim of a cyber attack, I needed something that would block signals from my hacked phone until I could get it professionally wiped, and to protect my new phone – these pouches are awesome as they stop everything, not just Bluetooth and NFC. I have bought several; my only slight gripe is that my S21 Plus with a protective case only just fits inside and it’s a bit of a squeeze, so they could be very slightly larger. Otherwise, top marks!
Brilliant value and it works,gave to family as a gift
I have purchased the defender signal blocker and also the defender “mini” signal blocker. These are the only pouches I’ve found that actually work and block signals. The mini pouch, perfect for just your key fob, with a key ring on the back for for the rest of your keys.
Excellent product, excellent service. Order quickly delivered.
Good quality strong fabric easily fits key fob /phone inside. Would recommend.
I ordered 2 of these Defender minis as I am having trouble with the back doors on my Mini Clubman they keep opening & it is very annoying, so I did a bit of research & found these Defender minis. They arrived very quickly & looked great & well made, I put my keys on the Defender & went to my car & when the key was in the pouch the doors would not open as soon as I took them out normal service was resumed. I would recommend these to anyone if car key security is an issue for you especially with keyless start cars as mine is as they are an effective piece of kit, easy on the pocket & easy on the wallet & give me good piece of mind that my doors will not open on my car without my knowledge & also your keys when in the Defender can not be scanned by thieves.
Brilliant as stated on the website- adds to a feeling of security in theses uncertain times
