What is a key fob signal blocker
A key fob signal blocker is a product that you put your car keys inside of to stop potential thieves from being able to interact with them. These signal blockers are usually designed in a box or pouch design. Car key signal blockers stop the radio frequencies of your vehicle keys from being visible outside of the blocker product, so stopping the key from interacting with your vehicle.
How do key fob signal blockers work
Key fob signal blockers come fitted with a Faraday cage which creates a shield. This stops radio signals from interacting with anything within the cage, meaning your car keys can’t be accessed to unlock your vehicle until removed. Faraday cages are used in many protection products for items that use radio frequency identification (RFID). Such products being RFID blocking cards, RFID blocking sleeves, and wallets to protect contactless bank cards.
In key fob signal blockers, the faraday cage is typically made from a foil-like material that lines the product. Some people will make a homemade keyfob signal blocker using aluminum foil. Although this will slightly work, it’s much more advisable to spend around $10-40 to purchase from a reputable manufacturer who has design experts create these products.

Best Looking signal blocker
The Vonetti Alpha shield is a premium car key fob signal blocking box made from high-grade machined aluminum. This gives a highly robust signal blocker with an extremely high-quality finish, as a result, this signal blocker looks extremely professional and impressive to the eye.
The aluminum measures 2mm thick and has internal dimensions of 3.2 x 0.8 x 1.6″. If your car or truck keys are smaller than this then Vonetti is the brand for you.
The inside is lined with an imitation suede which gives a smooth feel while the outside is colored black. This finish seems to be anodized and so will last much longer than any paint alternatives.
The only drawback to this key fob signal blocker is that it is quite bulky and can be a little cumbersome in your pocket if that’s where you store your key.
The blocking protection is very effective, with the box fully closed even next to your vehicle it will not be read so potential hackers have no chance! This key fob blocker is worth every cent if it stops your much more expensive vehicle from getting stolen.
Vonetti has recently released version 2, with an upgraded design. We will thoroughly review this before bringing the results to you.
Best key fob signal blocker for home use
The Orbis Global auto keyless entry fob signal blocker is great for use at home. One of the key reasons is a large capacity meaning the whole family’s keys can be stored. The internal dimensions are 6.3 x 4.7 x 3.6″.
This signal blocker can typically hold between 6 and 8 sets of keys depending on size. It’s made of artificial leather which gives a premium finish. This signal blocker will not look out of place around your home.
The only negative with this Orbis Global key fob signal blocking box is that you have to ensure the lid is fully closed to ensure the signal is being blocked. If left slightly open the protection is minimal and can leave you at risk. But a great redeeming feature is that you’ll always know where you left your keys.

The blocker comes with 2 pockets, one for a vehicle key the other for the likes of a bank card. Although I’d advise against having a contactless card in this pocket as you are susceptible to card skimming. Check out this to find out more about card skimming.
The inside of this blocker is 3.5 x 5″ so should fit any vehicle key. On top of being the best budget key fob signal blocker, it also comes with a lifetime warranty!
