Works better than others!
I tried other faraday bags to put my key FOB in so Turo customers can leave the keys in the car and they do ok but you can still start the car if you get the bag close enough. This one is way better and you can’t start the car no matter how close you get. It’s also big enough for any size key fob to fit. Great product!

100% Protection For My Application
These are the second pair of Keyfob bagsthat I have purchased from MOS. I use them as part of a "belt and suspenders" approach for keeping extra fobs in my Subaru's. I deactivate my spare fobs, place them in the bags and store them with the first aid kits in the cars. Subaru's have a feature that allows me to unlock the vehicles by entering a PIN code using the trunk release buttons.
In the event of a lost fob I can use the code to open a car and access the spare fob.
I also keep my key for my wife's 2026 Prelude in a bag since I keep it stored near the car and I want to prevent the close proximity from causing battery drain.

Great for blocking car key fobs
I've been using these faraday bags for a couple of weeks now. They seem to do the job, blocking the car remote from working when the key is placed inside of it.
