Best Key Fob Signal Blocker 2021

Published by

A car is robbed every 6.5 minutes in the USA, with keyless entry automotive theft (also known as relay theft) being an increasingly common crime. Thieves will break into cars and steal them without having to use the key fob by using relay systems. Faraday bags come in handy in this situation.

If you buy a new car that comes with a smart car key, you will be able to reach and/or start your car without having to take the key out of your pocket. But, you might want to consider investing in a key fob signal blocker.

Even though technology has made life simpler, it has also created a whole new way for criminals to steal cars. 

A smart key communicates with the car using a specific frequency, which can be replicated using a relay attack device by tech-savvy criminals.

If the key has been copied, the robbers simply place the relay unit outside the car to imitate the existence of the key. Just open the lock, and drive away without having to think about shattered glass, complicated ignition devices, or car alarm systems.

Since the signal is fully blocked inside the pouch, and though you put it in your pocket and the keys are mistakenly pressed, your car will not open. You can even carry the pouch around with you very quickly.

Here’s the VONETTI Alpha Shield 3.4 Inch Premium Keyless Go Security. This stops criminals from blocking the signal until you park and exit your vehicle.

It won’t allow them to break into your car with a signal extender after you’ve walked a couple of hundred meters away. That is why you must have theft protection that provides you with true security.

The signals can’t be fully covered with fabric bags. You’ll need a metal box or maybe an aluminum box to secure your wireless key. Since these boxes aren’t particularly attractive, we’ve designed a noble box for you that is suitable for storing your valuable items.

The VONETTI aluminum box is distinguished not only by its noble appearance but also by its durability. It has a two-millimeter thick wall, does not dent, and works flawlessly on all car models. Since the VONETTI box is milled from an aluminum block, it cannot be easily broken. You have a one-of-a-kind thing here.


Outside dimensions are 3.4 x 1.1 x 1.9 inch, and internal dimensions are 3.2 * 0,8 *1,6 inch. It is also lined with great imitation suede. Therefore your key doesn’t rattle, and no fingerprints stick to the lifeless black.

2. JXE JXO Faraday Key Fob Protector Box

After a while, all of the little signal blocking bags tend to look the same. As a result, it is normally done to determine how good the bags are evaluated and priced.

Despite their resemblance to the Monojoy signal blocking pouch and the fact that they come with two pouches, the POWR bags are included on this list because they are much less expensive and have outstanding Amazon ratings.

You need to carefully check the pouch’s reliability to ensure that none of the seams unravel, which is a common criticism about Monojoy pouches.
