The Science of Signal Security

The Signal BlockBox employs advanced signal-blocking materials that create an impenetrable barrier, called a Faraday Cage, around your key fob.

This prevents thieves from intercepting and replicating your fob's unique signal, thwarting their attempts to unlock and start your vehicle.

    Surprisingly Impressive

    I'll admit, I was a bit hesitant to buy another car security product, but the Signal BlockBox has been surprisingly impressive. It's super simple to use – just drop your keys in and that's it. I tested it, and my car wouldn't unlock with the fob inside the box. It fits both our keys. Definitely worth it for the extra peace of mind.

    Worth The Cost

    Honestly, I wasn't sure if this would be worth the cost, but I'm glad I took the plunge. It fits into my life effortlessly, and I don't have to second-guess where I leave my keys anymore. Considering the security it offers against car theft, which is rampant in my area, the price is a small one to pay. It's reassuring to know my car is safe, especially after seeing what happened to my neighbor's vehicle.

    Newfound Peace Of Mind

    I never thought much about car security until a rise of thefts in my neighborhood. The Signal BlockBox has given me newfound peace of mind. It's quite small but fits both our car's keys and doesn't stick out like a sore thumb in our hallway. For the level of security it provides, the cost is more than justified.
