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

Tested and works well, even protected bankcard in the outer pocket. Opens on the long edge so much easier to get keys out than from most other fob pouches on the market, which are also too big. I bought the smaller size, fits easily in pocket or small handbag. My husband was impressed and has ordered one for his car. Luckily I ordered bright pink so won't get confused with his (khaki). Also a nice cheerful colour.

Nice quality and lovely colour so it’s easy to find! Pouch is small so just enough to fit your car key plus one or two credit cards. Definitely works to block the signal! Arrived on time with additional emails from the supplier to check.

These work perfectly.I had my key fob in the pouch and pressed the open button and the car opened I was a little disappointed and thought they didn't work. I then closed the pouch flap and tried the button again nothing worked it completely stopped the signal even right next to the car nothing got through. I opted for these ones as they're one of the smallest I could find it fits my key fob and steering lock key just right. An added bit of security to help you sleep at nights.

Bought for Qashqia keys. Delighted with product. Fully effective e.g. cannot open doors with key in pouch right next to locked car doors. Quality is good. Need to take care to avoid damaging the foil pouch but at this price it's very good value and worth buying a couple.

fine at first, however has stopped working

Loved that this product actually worked. No issues at all but will be buying a bigger one as can only fit one set in due to us having other keys and key rings attached

Got a pair of these yesterday to protect my wireless car keys. To test, I placed one fob inside the pouch, and placedinside my jacket. I assumed that when I pressed START key on car, nothing would happen, but the car started as normal.Disappointed. Then placed on roof so there was that additional shield, but that made no difference either. **UPDATED**Have just read on a car forum, that pouch only works (re signal blocking) if key inserted in the rear, not the front compartment. Shame a simple leaflet wasn't shipped with item clarifying THIS VERY IMPORTANT POINT. Amazon Buying Team should insist on thiis being added.

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.
