This Key Fob Bag Really Works!

I was inspired to buy a key fob bag after reading an article about hackers and how keyless fobs like the one I own are being sus online one day. Putting my fob in a metal box or wrapping with foil didn't really appeal to me so when I found out these cool bags existed, I thought I'd give it a shot.

So, if you're like me and wondered (no offense SLNT!) "What if I just paid $30 for a bag that doesn't work?" you wouldn't be alone in your thinking. As it turns out, this bag really works! I have keyless entry to my Chevy Cruz. The other option to open the car without pressing the fob is to be within range of the car and press the button on the driver's side handle. I know this bag works because my car cannot connect to the fob at all. A few times when I was just getting used to it and would attempt to climb into my car while getting ready to go somewhere, I'd have to actually pull the fob out of the bag to get my car to open. Even being inside the vehicle and prematurely slipping the fob back into the bag to get out means the car will be unable to connect either. It actually does block out connection with the fob like it claims do to.

Surprisingly, the bag is also a great way to keep a better eye on your fob too. Sometimes I’d drop my keys into my bag and then have to fish around for them. Now that I have this designated bag, they’re pretty easy to find. Great job SLNT!


Good quality


Good but right to get bulky keys out. It works!!


I actually love this for my key fob. I don’t know if you know it or not but thieves now have some type of new device where they can scan your garage door or your house and once they find your key fob, they remotely start your vehicle and drive it away, so that’s why I bought my bag. I was using a box that had foil wrapped around it.

Stylish & Secure

This thing really works! The first day I got it I tried keeping my keys in the pouch while I touch unlocked my door and the car didn’t recognize the keys as being close by. Will definitely recommend to my friends with keyless entry.
