Minder Signal Blocker - Jamming Case/RFID Blocking Pouch for Keyless Entry Car Keys & Mobile Phones - Faraday Bag Protection - Security against Relay Crime (Red, 105mm x 64mm (Internal))

Blocks out signals. Our car got stolen off our drive and we have now made precautions, one being purchasing this signal blocker. My husband could not open his car in this pouch. Excellent gadget.

I had my car broken into using a keyfob booster, bought this as advised by the police and it works perfectly. Now keep one in my handbag as thieves are targeting car parks. Don’t forget one for your spare keys!

This pouch is great for putting car keys or credit cards in, to protect them from bad men trying to steal stuff.They can be used to protect anything that emits an electronic signal, not just keys. For example, if you had a tiny evil robot that communicates electronically with his friends to organise worldwide domination, this pouch would stop it, so this pouch could save the world, that’s how important it is to buy one.

Having read a couple of articles decided we needed to protect ourselves against potential car theft. Bought two as spare fob also needs one. It’s proven useful as the keys are now always put in the cover and placed in the same place. Tried to open car with keys in bag and couldn’t so have proved it works.

Though this worked when purchased, it stopped working (ie blocking signal) after a few months, I'm guessing due to the front door key or something damaging the signal blocking material on the inside of the pocket:(Bearing in mind it was only used in the house, not going out & about in the car....)

I've bought a number of these recently due to a spike in car thefts in the area involving thefts without need of a key.Yep, if you leave your car fob near your front door your car is at risk of being stolen and never seem again.This very simple yet clever bag blocks the RF (radio frequency) signal that would be thieves use from a scanning device to locate your keys then use a signal booster to act as a jumper from your keys to the receiver build into your cars ignition. Instant access and ability to start your car especially if it's keyless push button start. This simply prevents the signal from being detected on your keys. BUT BE ADVISED! You will need to ensure your spare key is also in a RF bag or it will still pick up a signal.

This little soft pouch works perfectly. I cannot open the car door with the car key in the pouch, even when I'm standing right next to the car. I've been using it for a month now and the pouch has withstood the wear of being kept in my jeans pockets.I'm keeping my spare car key in the house with the battery removed, so that I don't need to buy a second one of these.

Fits a large car key perfectly, with key ring and one additional small regular key.This brand's products are recommend by the police as 'Secure By Design', which is reassuring.
