ULGAI Signal Blocking Pouch for Car Keys Twin Pack, Car Key Signal Blocker, Faraday Bag For Keyless Entry Car Key Fob, Anti Theft Guaranted, Block RFID/WiFi/GSM/LTE

Bought on recommendations from viewing Social Media. Following a spate of car breaks for petty thefts, someone said these worked.. Thought I would give a try, as not wasted a lot a lot of money. Hopefully they will do the trick. Also got another set for daughter.

I've tired it on my mitsubishi. Simply does not work. Maybe its the new duracell battery I put in the key. But no, pouches don't work.

Extremely effective, only downside is the size, much larger than I anticipated, but small price to pay for peace of mind over car security.

Very good at blocking the key signal even when your stood next to the car

Work fine and block the remote signal.

They work! Prevent remote access to a vehicle by thieves.

They work the car would not open when they are in the case

Little bit small for my rather big mini key with other keys on ring
