## Description

TOMKAT Car Key Signal Blocker, Small Faraday Box - Car Key Signal Blocker Box This small box faraday cage and complimentary pouch will ensure 100% protection from car thieves that use sophisticated skimming tools to lock onto the key fob signal to fool the car into unlocking the doors and allowing the vehicle engine to be started. The device is designed specifically for blocking out all radio frequency signals being transmitted by your keyless entry remote control so that it cannot communicate with your vehicle's electronics. No more worries about your car being stolen or broken into! This small box faraday enclosure is a portable and compact device that can be carried around within your pocket, purse or conveniently clipped onto your keychain. It is made of durable plastic and metal mesh to protect the key fob signal from outside interference. The car thieves will not be able to access the signals being transmitted by your car keys as they are completely blocked by this small yet powerful device.

## Features

- Protecting Your Valuables - Works with all car key fob types. Simply place your keys into the box or pouch, close the lid, and lock it away! Your faraday pouch for car keys will effectively stop any form of wireless signals from being transmitted in and out of the enclosure.
- Premium Carbon Fiber - The faraday cage, with its matching carbon fiber material design, looks good enough to eat. Once the keys are located securely within the closed rfid key pouch or box the signals are 100% blocked so you can sleep easy at night.
- Home or Away - It's always a relief when you can slip your car keys into the rfid key box and feel 100% secure knowing they're safe from intruders. It may seem like an unnecessary luxury, but this little keyless car key signal blocker pouch is a must-have!
- Perfect Faraday Gift Set - The gift of safety is a great present that will be well received and appreciated! Our signal blocking box for car keys can hold up to 6 keys depending on size catering to several family members, that's value for money!
- The TOMKAT Promise - We are so confident that you will love your faraday pouch and box, we have backed it up with a 30-day money-back guarantee. Please contact the UK customer care team, we will reply to you within 24 hours to make sure you are satisfied!

*by L***Y on Reviewed in the United Kingdom on 5 January 2024*

Already have one for myself works perfectly unlike other makes I've had worked for 5 mins then nothing. This one I've bought as a gift for friend.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Lid must be closed fully on box to block signal.
  

*by R***Y on Reviewed in the United Kingdom on 8 February 2023*

Tested and found to work. Nice compact size which fits a Ford car key/remote together with house keys. First delivery was missing the pouch. Sent that back & ordered another which was then slightly more expensive! Which is why it hasn’t been given full stars.
