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.

Even though technology has made life simpler, it has also created a whole new way for criminals to steal cars. You may want to consider investing in a Faraday bag to protect yourself.

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.

Best Key Fob Signal Blocker

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.

Key Considerations when buying a key fob signal blocker


Make sure the blocker you buy will block a signal from a certain number of feet away. Also, make sure that the label on the package indicates which key fobs it can block.


It’s good to know what percentage of people have successfully used this device before buying one yourself. There are products out there that claim over 95% success rate.

Ease of use

Consider the ease with which you can carry this device around, as well as how simple it is to use. Some products come in a pouch that fits right into your pocket, while others might be quite a bit bulkier and not suitable for carrying around.


The material the bag is made out of determines its ability to block signals from key fobs. There are fabric-based bags that will allow some wireless communication through them. Still, nylon ones will stop all signals from going through them.


Some key fob signal blockers cost about $100 a piece, while others go for upwards of $200. Consider what features you want to be included before paying any price for one of these devices.

Choosing the right key fob signal blocker

Among the considerations listed above, price is not a very important factor. That’s because many products out there come at different prices and offer similar performance and features to one another. Having said this, it pays to get the most value for your money: look for something that gives you excellent quality at an affordable price. You should also make sure you can carry your device around with ease, as well as how simple it’ll be to use it when needed.

The most important thing to remember when investing in a key fob signal blocker is that it will NOT stop you from using your car. Instead, it’ll simply block the signals of the devices used by thieves to steal cars.

Frequently Asked Questions

Do signal blockers work? 

The short answer is yes, they do. However, it’s important to note that they will not work for everyone because there are a few factors that could affect the device’s performance: how far away you place your key fob from the blocker when using it and what kind of fabric made up the material of the bag (nylon or cloth).

Who needs one of these devices? 

You might consider getting one if you often find yourself in situations where you need to carry around valuable items on your people, such as purses or laptops. This way, you won’t have to worry about someone stealing your things by using a wireless signal while standing near you.

Are these devices legal?   

Well, yes, they’re not illegal to use and own. However, every state has its own laws regarding carrying around knives or any other kinds of bladed weapons that could cause harm to yourself or another person. This means that depending on where you live, it’s possible you could get into trouble for carrying one of these devices. For example, if you live in a state like Texas, it’s illegal to carry around such an item without good reason.

How does a key fob signal blocker work?

The key fob signal blocker is a device that sends out an electromagnetic field in the space around it, preventing any wireless signals from getting to or from your car. If you place this at home and walk outside with your cellphone, for example, then as soon as you step into a range of the key fob signal blocker’s electromagnetic fields, they will disrupt all data connections between devices-including Wi-Fi networks!

How do you use a signal blocking pouch?

Signal blocking pouches are the perfect way to keep your keys safe. Simply place them in the pouch when you’re not using it, and if something goes wrong while you aren’t keeping an eye on either of those things – then no worries! Your car is still there for you to drive away from any potential danger that may come knocking at your door via signal-blocking technology.

How do I know it is working?

The key fob protector is completely undetectable to those around you. However, if a credit card or membership card is swiped through a machine near your key fob, it will not work. This means that you will always know when someone has tried to scan your cards without your knowledge and approve transactions fraudulently.

What is EMF?

Electromagnetic Fields (EMF) are invisible electrical fields that are always around us. They are generated by anything with electricity: TVs, radios, lights, and computers. These fields surround the wire carrying the current and extend outward into space a very short distance, sometimes for several feet or more. The farther away from the source you go, the weaker they become until they eventually reach levels of “background” EMF (from power lines near your house or appliances in your home).

EMF is not to be confused with electromagnetic (EM) radiation (such as microwaves), which has a longer wavelength and higher energy than an electric field. Also different from EM radiation is ionizing radiation, such as x-rays and gamma rays, which are known to be dangerous and can cause cancer.

What material can block EMF?

Newer style metal-link fences, made with a network of interlocking steel mesh links, are the best at deflecting electric fields. The fence has to be fairly close to the ground in order for it to work, though.

EMF protection varies by material. Most materials offer some protection, while others are nearly useless. The best are:

Metal mesh links – interlocking steel or aluminum mesh links, made into a fence and close to the ground (like about 6 inches). Inexpensive chain link fences protect fairly well.

Non-conductive coatings or paints containing carbon particles. This overlays walls on homes and is called “carbon nanotube paint“. The coating must be applied several times as it wears away quickly; also, it is expensive ($100 per gallon). Such paints can block EMF from power lines, cell towers, satellite towers (ham radio), and WiMax towers. It will not do much for other types of EMF, such as items in your home, electric appliances, or your computer.

What Is A Faraday Pouch?

A Faraday pouch is a bag lined with an electrically conductive material, typically aluminum foil. The use of this protective device was originally developed to protect sensitive electronic devices from damage due to electrostatic discharge (ESD).

The Benefits Of Using A Faraday Key Fob

Faraday bags are now commonly used to protect sensitive electronics. The technology is based on the principle that it is possible to shield an electronic device from electromagnetic fields by enclosing it in a conductive material such as aluminum foil. RFID tags operate on radio frequencies, and this type of shielding works against both digital and analog signals.

Final Words

We’ve probably analyzed the five best Key Fob Signal blockers, which have Metallic lining that offers a total signal blocker for your car key fob.

This prevents thieves from picking up and relaying signals from the key of yours to shield against keyless ignition theft and break-ins. Protect credit cards along with other electronic items.

This multi-purpose security pouch can be used for bank cards, the access card, key fobs, and other small smart devices that store electronic data at home or on the go.

The pouch would block all signals to and from your device, stopping criminals from controlling and accessing it remotely. So, what are you waiting for? Choose what is appropriate for you.
