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.

Product made from good material that should last a long time. Went for the medium size so could get not only car key but other keys and key fob in too.

Fit keys and phone in if needed, however if you phone is too big you might struggle.
