Minder Signal Blocker - Jamming Case/RFID Blocking Pouch for Keyless Entry Car Keys & Mobile Phones - Faraday Bag Protection - Security against Relay Crime (Red, 170mm x 105mm (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.

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.

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.

Value for money.

Stopped working after 2 months! Initially Initially I would have given 4* as I liked the size, the bright colour (so it stood out on my handbag) and the chain to attach it to my key. However, despite taking good care of it it as stopped working after almost exactly 2 months and is therefore useless. Very disappointed.

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.

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.

About 1 year ago I purchased a new car all singing all dancing. Electronic this electronic that. So after hearing about all the thefts of cars with electronic wizardry I thought I purchase these pouches to protect the keys.....i know own 4 pouches .today son in law who's in motor trade bought his wifes car over and asked where it's safe to put her keys o said in the pouch he said have u checked it works and i hadnt ..so we put her keys in pouch (key in sealed pouch) went to her car it opened and started....so we tried same with my car ( my key in pouch sealed ) went to car operated button through pouch sat in car with key in pouch car stated first time ... these pouches just dont work do no buy of u want to protect ur car from theft

great for storing key fob near the front door for my easy access, but block access to those who would want to steal the vehicle
