The Defender Signal Blocker is a high-quality faraday pouch; dual-purpose vehicle fob and mobile phone storage pouch.
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.
When sealed inside the pouch, proximity fobs are fully protected from tech-savvy car thieves, ensuring your vehicle cannot be stolen in this manner.
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.
Best selling ‘faraday bag’ available, winning awards for its exceptional quality and performance, as well as achieving the coveted Secured By Design Police Preferred Specification.
Beware of imitations! The Defender Signal Blocker is the only blocking pouch to feature industry-leading RPF™ material.
Our new and improved design features a handy hook to attach to key rings or lanyards.

Why not check out the Defender Signal Blocker Mini?
Just ideal for pocket and also indoors
The wonderfully inefficient Royal mail managed to lose the order but when I queried the delay two more pouches were sent out straight away. No hassle and brilliant service. AND the pouches work superbly. Place your keys on the bonnet in the pouch and the car is secure. Excellent!
No need to have sleepless nights worrying if your car will be their when you get up in the morning.
It works
A genuine Defender Signal Blocker car key/mobile phone faraday cage pouch supplied by Redline Security. Completely effective in use as tested & reviewed by Autoexpress. A top quality, value for money product delivered quickly & securely.
Very pleased with the pouch
Seems to be well made. Successfully blocks car key signal.
Very quick delivery and the product does exactly what it’s supposed to do. It’s very efficent even up to the car there’s no signal. Highly recommended
Does what it says on the tin. Good price
Received, a couple of days after an email saying order completed. I’ve previously bought several of these pouches from the well known auction site. ALL worked well on receipt and yet when I checked the signal blockers capability around six or seven weeks later, non of the pouches work. I have purchased cheap and expensive pouches and found non block any singles after 6 or 7 weeks. I wait to see if this pouch is any different. It looks nice and it works well on day one. I live in hope………..🤞
