Defender Signal Blocker Faraday Pouch FAQs – Secured by Design
Is this product Secured by Design / Police Accredited?
Yes – this Defender Signal Blocker holds official Secured by Design Police Preferred Specification accreditation. It is independently tested and recommended by UK police forces as an effective theft deterrent.
What is the difference between Standard and Mini?
Standard (16 × 9 cm) is the most popular for everyday use. Mini (12 × 7 cm) is more compact for smaller pockets or key fobs. Both offer the same high-level signal blocking.
Will it work on non-Defender vehicles?
Yes – it works on any vehicle with keyless entry or keyless ignition, including Tesla, MG4, VW ID series, Range Rover, BMW, Audi and most modern cars.
How effective is the signal blocking?
Extremely effective. The double-layer military-grade Faraday shielding completely blocks key fob signals (315–868 MHz) when the fob is inside the pouch.
Do I need to use it every time I park?
Yes, for maximum protection. Simply place your key fob inside the pouch whenever the vehicle is left unattended.
Is one pouch enough or should I buy two?
Many customers buy the twin-pack so one stays with the car and one at home, or for two drivers. Both sizes are available individually or as twins.
How do I test it works?
Place the key fob inside the pouch – your car should no longer unlock or light up when you approach. This confirms the signal is blocked.

It Does What it is designed to do

This is the best product of its kind on the market. I’ve carried out extensive tests and they have the highest RF attenuation of any competing product. EV Accessories also have the best price on the internet.

Fast delivery from EV bought these after seeing news reports of keyless cars being stolen, well made and by seeing other reviews I hope will never actually need them

Fast delivery from EV and best price I could find on the internet. Put my key fob in it, placed it on the centre console in the car and it worked brilliantly. No signal and the car would not start. Thanks EV.

Well made product which passed every tert that I gave it. Keys and phone should be perfectly safe from remote cyber attack now they’re in the Defender.
