Review on 🔒 Red X-Small Silent Pocket Signal Blocking Faraday Key Fob Case - Advanced Car Anti-Theft Shielding Technology Blocks All Signal Types, Including RFID Blocking - Durable Faraday Bag, Fits Most Car Keyfobs by Bill Lacy

This item still looks like new because I take care of my stuff. But the RF blockage doesn't last long. I bought it on August 11th, 2020 and for the last month or two I've found that it doesn't work. I could put my key fob in my pocket and put it in the trunk and the trunk lid would not lock, which on new cars is used to not lock the trunk if it finds the key fob in the truck so you don't accidentally find the keys lock . trunk. But if you rock and want to lock your keychain securely and only carry a metal key with you, I can't do that anymore. About 9 months and it no longer works. I bought two different new products that work the way I want them to, at least for now. I'll get back to you in 9 months. I tested FOB in this case and in two new products by opening the doors and driving. I put my FOB in each product one by one to see if my car starts. The old bag couldn't stop my car from starting. Two new products blocked the signal, at least for the time being, and I couldn't start the car. Perhaps the companies selling these products should make it clear that their product has an expiration date?
