Product Description

Faraday pouch or bag shield for keys with keyfob works by shielding "always-on" keyfobs and other small electronics (like Apple Watch, transmitters, and credit cards) from radio frequency signals. This ensures that the device cannot get hacked and the signal it constantly emits cannot be boosted. The bag should be used as a preventative measure for vehicle and data security. It also allows you to keep a spare key fob isolated and locked inside your vehicle. It works to stop radiation on all wireless frequencies and platforms such as 2G, 3G, 4G, LTE, and 5G.

Protect Your Keyfob With This Faraday Bag.

Learn the trusted, high-security method to prevent signal amplification from your keyfob.

Automotive security community has a new threat: unwanted or illegal entry into a vehicle by using signal boosting methods to amplify keyfob signals. Unfortunately, criminals and would-be car thieves are using signal booster devices to mimic or boost the signal from a keyfob to gain entry to a car without resorting to forceful means.

Luckily, technology is usually only one small step behind the latest criminal practices. This Keyfob Shield is a faraday bag that works to block signals from a keyfob, preventing communication with the car and keeping your vehicle secure. Manufactured from the highest quality materials, this Key Fob Shield is water-resistant and highly durable. Its interior is constructed of Titan RF faraday fabric in three layers, while the outer is a ballistic nylon. Even the dual paired seams are of the highest quality and go that extra step towards ensuring the robustness of the device.

Keyfobs are a type of "always-on" signal emitting technology, much like credit cards, transmitters, and smartwatches. The faraday bag shields these devices from radio signals which could potentially hack the device or boost its signal for easier access. This Keyfob Shield prevents this from occurring by creating a barrier to prevent signals from being transmitted or boosted.

As a bonus, this Key Fob Shield can also be used to keep a spare keyfob locked inside your vehicle - an exercise that has been prevented by the very design of modern vehicles. This faraday bag is proving useful not just with domestic and business motor vehicle security but for personal security, data privacy, forensics, and to aid with executive travel.

It is large enough to fit two average fobs or a standard set of keys with the usual accessories. The keyfob to be protected should stay within the Keyfob Shield at all times, except when being used. This is an ultimate way to ensure the security of your vehicle.

Mysterious Vehicle Thefts Around The World.

Keyless entry systems are touted as one of the best motor vehicle inventions in recent decades, but they bring with them new ways for criminals to gain access to your car without resorting to forced entry methods.

Find out more about how these clever criminals are hacking keyless entry systems, and how you can use this Key Fob Shield to make sure you never fall victim to this type of crime.

You have probably heard the story countless times on the local news: another criminal has gained access to a car with a keyless entry system by using a "mysterious radio device". Shrouded in mystery, vehicle owners and law enforcement personnel alike are baffled as to how these crimes are taking place without forced entry, in broad daylight, and often in cars parked in the owner's driveway.

How is it possible that a vehicle owner can lock their car and leave it in a safe place, only to later return to find that a criminal has entered their car and stolen their belongings - or even stolen the vehicle itself? Even more baffling is that there is usually no sign whatsoever of the car having been tampered with. No broken glass, no bent coat hangers, and no obvious entry points.

Some of these mysterious crimes have even taken place in full view of security cameras. When viewed later, the footage shows the criminal simply walking up to the car and opening the door. How is this possible? Does it mean that the car was never locked in the first place? What about vehicle owners who swear that they locked their car, and even remember going back to double-check?

Here, we unravel the mystery and explain exactly how you can keep your vehicle protected from keyless entry thieves.

When we think of hacking, we often think of computer systems but unfortunately almost any digital device can be hacked. A keyless entry system of a motor vehicle is just another digital device, and in many ways is not dissimilar to a computer. For a criminal with basic hacking knowledge and a few inexpensive devices on hand, hacking a keyless entry system is a quick and simple task.

Before we explain further, it is important to understand that the keyfob from your keyless entry system is always broadcasting a signal. The signal may be very faint, but it is still always on and always broadcasting. With this knowledge, here is a better understanding of how keyless entry system crimes take place. After watching you walk away from your vehicle, the criminal puts themselves within your vicinity. They use a simple power amplifier to broadcast and amplify the very faint signal coming from your keyfob, before directing it back to your car. This signal tells your card that you have returned to the vehicle, causing it to unlock as designed.

It is such a simple crime, and it can happen to anyone with a keyless entry system on their motor vehicle. Luckily, technology has caught up with the criminals and there's a handy, inexpensive device that can completely prevent this type of crime from happening to you. All it takes is for you to be proactive and keep your keys shielded from outside interference when they are not being used.

Our Keyfob Shield is the shielding solution you need to keep yourself and your car safe.

Keyless entry motor vehicle systems work by waiting for the key to be within a few feet of the door, at which point the key communicates with the keyless entry system within the door, unlocking the car without you having to press a button or physically use your keys. The system is designed so that the car door only unlocks when the key is within a very short distance. However, a signal amplifier can be used to broadcast a very faint signal - which is designed to be used over a distance of a few feet or less - to distances of several hundred feet.

This means that, if your car is parked in your driveway and your keys are inside your house, a criminal can use a signal amplifier to broadcast the weak signal coming from your keys, making your car think that you are standing right next to it. This practice is not only limited to residential buildings, but is increasingly happening at sporting events, business premises, highly populated streets, college campuses, and shopping mall parking lots.

Millions of people in United States alone already use keyless entry systems, and this number will continue to rise as keyless entry becomes the new technology in car security. As law enforcement officials work to get on top of this new high-tech crime, there are two important pieces of advice to follow:

  1. Don't leave valuables in plain sight within your vehicle. It may seem overly simple, but if a criminal can't see anything of immediate value within your car, that could be all the deterrence they need to target someone else rather than you.
  2. Keep your keyfob in our Keyfob Shield at all times when it is not being used. This simple technology prevents criminals from amplifying the signal from your keyfob. If you make it too hard for criminals to target you, they will move on to someone else.

The Keyfob Shield is the only faraday bag currently being sold that is constructed by dual paired seams with an average attenuation of 60 to 80 dB that can block all signals including radio signals, RFID, GPS, 4G LTE+ cell phone signals, Bluetooth, and 2.4 and 5 gigahertz Wi-Fi. Simply slip your keyfob into the bag, then use the loops to attach it to your belt, keyring, or put it in its usual position inside your purse or pocket.

Isn't it amazing that for roughly the same price that a criminal will spend buying a signal amplifier to try to steal your car, you can buy a faraday bag to protect your car from the same technology?

Even better, the Keyfob Shield doesn't just protect keyfobs. The same technology can be used to protect security badges, credit cards, smartwatches, and all other small devices that emit a faint signal.

Some people claim to have a home-made faraday bag, and talk of techniques like covering a device with aluminum foil, putting it in the freezer or storing it in a metal container. Unfortunately, while these ideas sound good in theory, they are not completely effective - nor are they practical solutions for everyday life.

For even greater protection, pair your new Keyfob Shield with car control and remote start apps like OnStar Remote Link or Viper SmartStart. Then you can keep your keyfob inside your new faraday bag at all times, and only remove it when you need to drive your vehicle. These apps simply require the keyfob to be located nearby. This means that you can allow family members to drive your car without physically transferring the keys over. When your family member is ready to drive the car, you simply take the keyfob out of the faraday bag and allow access using the app.

As a bonus, this technology allows you to keep a spare keyfob securely stored within your car. Modern motor vehicles don't allow keyfobs to be kept inside, which is a good idea in theory but not much help if you want to keep a spare keyfob inside your car in case something happens to your primary fob. By putting your spare keyfob inside a Keyfob Shield, you can hide it securely in a compartment within your car. If you ever lose your primary keyfob, you can simply call a locksmith to unlock your car, allowing you to retrieve the spare keyfob inside.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

For non installation-included kits: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
