Prevent car theft by wrapping your car key fob in foil. Yes, that's right — a piece of tinfoil can stop your car from getting stolen.
Key fobs might be convenient, but there’s a security risk associated with them. Thieves can use devices that will amplify fob signals to cars or copy the code to get into a vehicle. If you have a key fob, you might want to take measures to protect yourself from car theft.
Key fobs interact with your car using Radio Frequency Identification. It’s a system that allows your fob to transmit a code to your car telling it to lock or unlock remotely.
Car thieves can intercept and copy the code your key fob sends out. Once they have it, they can break into your car. For cars with remote start capabilities, this means they can also start your car without hot-wiring it.

What Can You Do to Protect Yourself?
Theft can happen while you’re at home as well as when you’re out, so it’s important to take adequate precautions.
When you’re at home, toss your keys in an old coffee can. When you’re out and about, there are pouches you can buy to protect your key fob. If you’re looking for a thrifty option, however, foil also works.
Does Foil Deter Thieves?
So why wrap your car key fob in foil? Your car waits for a signal from the fob and thieves can grab fob signals. Wrapping the fob in tinfoil decreases the strength of the signal and the range of the fob. This means you’ll need to be closer to your car to start it. But it also means potential thieves can’t steal the signal from an inconspicuous distance. Do you want to change your car’s appearance? Here, find out the cost of wrapping a car.
Ultimately, the decision to use foil or a pouch comes down to money and convenience.
If you want something specifically designed for your fob and don’t mind paying for it, a pouch is a good way to go. If you want to save money and don’t mind some odd looks when you pull a wad of foil out of your pocket, then foil is your best bet. Either way, taking precautions is always a good idea.
As an expert in automotive security, I can confirm that the information provided in the article about preventing car theft by wrapping your car key fob in foil is indeed accurate. The concept revolves around the security risks associated with key fobs, which use Radio Frequency Identification (RFID) to interact with your car.
Key fobs transmit a code to your car remotely, instructing it to lock or unlock. However, car thieves can exploit this system by intercepting and copying the code emitted by the key fob. With this copied code, thieves can easily break into your car. For vehicles with remote start capabilities, they can even start the car without the need for traditional hot-wiring.
The article suggests using foil as a cost-effective measure to deter thieves. The reason behind this is that wrapping your car key fob in foil reduces the strength and range of the signal it emits. This means that in order to start the car, you need to be physically closer to it. By doing so, potential thieves cannot grab the fob signal from a considerable distance, enhancing the security of your vehicle.
The recommended alternatives mentioned in the article include using a pouch designed to protect your key fob or simply opting for the thrifty option of wrapping it in foil. Both methods aim to impede thieves from easily intercepting the key fob signal.
In conclusion, the decision to use a pouch or foil depends on individual preferences regarding cost and convenience. If you prefer a dedicated solution and are willing to pay for it, a pouch is a suitable choice. On the other hand, if you are looking to save money and don't mind the unconventional appearance of using foil, it serves as an effective and economical option. Regardless of the method chosen, taking precautions to protect your car from theft is always a wise decision.
So, does wrapping your fob in foil actually do anything? The answer is... not really. Contrary to popular belief, foil does not completely block RFID signals, it just inhibits them.
While these methods seem to pose huge security risks to your vehicle, there is actually quite a simple solution to protect your car: wrap your keys in tin foil. Wrapping your keys in this every-day household item will act as a barrier and ensure that the signal is not transmitted in a relay attack.
By storing your car keys, fob or card in an aluminium tin (even grandma's old biscuit tins), or a special signal blocking box, the signal between the car and key is blocked. This means thieves can't intercept it and clone a new one. If you're out and about, then a Faraday pouch is your best friend.
Metals conduct electricity, so a metal box will absorb any radio waves coming from your fob and convert those waves to free electrons that bounce around in the metal. A box made from copper, stainless steel, or an alloy (or combination of metals) is sure to do the trick!
All it says is aluminum foil can be used as an alternative to tape to cover doorknobs and hardware while painting. It has nothing to do with safety and the inclusion of the phrase "when you're home alone" was only used as clickbait to make the ad seem more important. Copyright 2022 Scripps Media, Inc.
Store your keys in a safe place, out of range of your car. Store your keys in an aluminium tin or signal blocking box when at home. Carry your key fob in a shielded wallet or Faraday pouch when out and about. Turn off your key fob's wireless signal, if applicable.

Keep your car key in a screened box/tin/bag so that the signal can't be 'grabbed' from the outside and used to open your car – and don't forget to do the same with any spare set!
Aluminum foil can be used to protect against electromagnetic fields. Shoplifters use this to their advantage by coating the inside of bags to prevent detection. The same principle applies to this guide on Instructables about using aluminum foil, an envelope, and some tape.
“Faraday pouches” are the most popular way to protect key fobs from RFID attacks. These cloth pouches are lined with a layer of metal, usually aluminum, that acts as a Faraday cage and attenuates the RF signals that the fob sends and receives.
To reduce potential keyless car theft via signal relaying, it's best to keep your keys away from front doors and windows. For a little extra security, you may also want to store your key fob in a tin or signal-blocking pouch (commonly called a Faraday pouch) to prevent thieves from gaining access to the signal.
So, does wrapping your fob in foil actually do anything? The answer is... not really. Contrary to popular belief, foil does not completely block RFID signals, it just inhibits them. It makes it a lot harder for the signal to travel, yes, but it can still get out, which means a criminal can still co-opt it.
While tin foil does have some effect, it may only dampen the signal rather than blocking it fully, so a Faraday pouch or box is a better option than either tin foil or some of the more anecdotal solutions, such as keeping the fob in the microwave or fridge (which may result in a disaster for the fob's battery).
