Did that, No Key detectedHello; Have not tried this with a key fob, but it did block a cell phone. I cleaned the bag my coffee came in. Put my cell phone in it and tried to call it. Did not get the call.
If you try such with a key fob maybe put the fob in the bag and walk up to the car and or sit in it. Then try to start or operate some system. I may be wrong but suspect if you walk up to a car which has a key fob system the doors will unlock as you approach. If such is correct the fob in a coffee bag ought not let such happen.
Likely is there are other such bags to try.
I bought some RFID blocking holders in which I slide credit cards with chips to do the same thing.
