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?
Product is very good quality at a competitive price
Absolutely fantastic product & great price would recommend to anyone keep up the good work.
Excellent value for money as you get 2 pouches. They hold car keys and also a phone which is an added bonus. We were advised to buy these by a friend mainly to protect against car theft but it’s great to have the option of using it for phones as well.
The pouches are well-made from strong material and not too bulky. Would recommend.
I bought the Defender key protector and it did work well for about a month. However, last night discovered I can know open and close my car and even start it while it is in the pouch. So in other words its now pointless. I appreciate things get worn, but a month is not really acceptable. Advise look at alternatives.
Good service, fast delivery. Very happy with product.
Great product at a good price
A faraday pouch that really works.
Appears to be larger than the previous version but still works great!
Very effective. If car keys in the bag, car will not start even though it is in the central open pocket
I bought the Defender Blocker Mini via Amazon in December for a planned new car. It may have worked OK previously but today I discovered I can open the car without removing the key from the pouch and even drive my car like this. I only had to take it out of the pouch to lock the car. Fortunately I belt and braces at home and keep the key in the pouch in a tin as well.
