Review: SMALL BOX ONLY: Excellent, blocks FindMy! - THIS IS A REVIEW ONLY OF THE SMALL BOX. I notice that the other box sizes appear to be built/sourced differently than the small and the largest looks like one I am returning because it doesn’t block. Not saying it’s the same one as here, but I want to make clear I’m reviewing only the small. And as for the small- I placed my Apple Watch inside, triggered sound on “Find My” and waited for half an hour without triggering the alarm. Opened the box and seconds later the watch began to sound the alarm. This was done with my phone and ipad inches away from the box. Successful blocking to my requirements. This will fit multiple key fobs perfectly, so my main one and spares are safe. Construction is good, latch is tight but movable, for price paid I’m very happy. Wish the large also looked like this model and I’d buy one, but as I say the appearance of large is different- different latch, different materials, and looks like one I’ve already tested that failed right away so not going to bother.
Review: Tested and works - This rating is for the small box. The medium and large sizes appear to be a different style. The box is big enough to fit my entire keychain, which consists of a key fob, two house keys, a small flashlight and a large beaded keychain. The clasp is easy to open and close and I like how it looks on my countertop. I tested the function of the faraday box and it works well. My car did not detect the key fob inside the closed box, even while holding it directly next to the car.

## Questions & Answers

**Q: Did anyone try putting car keys in box, close the box and bring near your car to test if the car unlocks or not?**
A: Yes I did bring the box into the car and tried to start it. The car did not know the key was in there. Works great

**Q: What is the largest capacity for this box? measurements is ?**
A: I'm not sure of the actually measurements, but I'm able to fit three sets of car key rings that include car key and several other keys in the box.

**Q: anyone tests this box for opening the car door?**
A: Yes, I tested it the first day I received it from Amazon.  The box works.  I opened the car door first.  Sat in the car with the key in the box and the key was not detected, my car didn't start until I opened the box and removed the key.

**Q: Have the box, but cannot determine if it operates. Since the box needs to be fully closed with the key fob inside, how is it able to be tested?**
A: If your car has the ability to sense the keyfob on you, keep the box in your hands and try to open the door. If it doesn't have that ability, An easier way to test it is put your cellphone in it and either call it or have someone call it. If it doesn't ring, it works.

*by J***K on January 14, 2026*

Excellent fob storage box works perfectly! Tested by me I placed the 2024 Cadillac FOB in the container and stood side by side side of the car and the car still did not pickup the signal. It does Exactly what it states it does! Easy to use just open the box and place your key FOB in to test its absolute safe storage of multiple Fobs.
