It might sound daft at first — after all, who keeps car keys next to last night’s curry? — but this quirky trick could protect your vehicle from high-tech thieves. With relay attacks on the rise, drivers are turning to household items for a simple, no-fuss defence. And surprisingly, your kitchen microwave might just be your car’s new best friend.
A kitchen hack that could outsmart car thieves
Storing your car keys in the microwave might sound like a scene from a comedy sketch, but there’s a surprisingly clever reason behind it. And no, it’s not because your keys need reheating. It’s all to do with a rising type of car theft that targets vehicles with keyless entry systems. The technique criminals use is called a relay attack, and your humble microwave might just be the shield your car needs.
The sneaky trick thieves use to nick your motor
If your car unlocks at the touch of a handle — without the need to fumble for keys — it’s running on a low-power radio signal between your fob and the vehicle. That’s where the trouble starts. High-tech thieves now work in pairs: one stands near your front door, the other by your car. With special devices, they capture and extend your fob’s signal from indoors and transmit it to your car — tricking it into unlocking, and in some cases, starting.

It takes seconds. Literally. A quick zap, a door click, and they’re off before you’ve finished your morning cuppa.
Why your microwave might just save the day
Now, here’s where things get a bit James Bond. Microwaves — when switched off, obviously — are essentially mini Faraday cages. Their metal casing blocks electromagnetic signals, including the ones your key fob constantly emits. That means when your keys sit inside one, even the smartest criminal tech can’t intercept their signal.
It’s a quirky fix, sure, but physics backs it up. That said, don’t get carried away. Never switch the microwave on with your keys inside — or anything metal, for that matter. You’d be looking at sparks, damage, and possibly a kitchen fire. Not ideal.
Better ways to block signals (without risking your microwave)
While the microwave trick can work in a pinch, it’s not exactly the most practical long-term solution. For starters, if someone accidentally turns the thing on, you’ll be needing a new fob. Or worse — a new microwave.
Instead, go for Faraday pouches, which are designed specifically to block signals. They’re small, affordable, and can sit on a hallway table without looking out of place. Other solid options include metal tins (with tight-fitting lids), lockboxes, or even an old biscuit tin. The key is no gaps — signals will slip through the tiniest crack.
And while some swear by the fridge or even wrapping keys in aluminium foil, these aren’t foolproof. Foil tears easily and fridges aren’t always properly sealed against radio waves.
Everyday habits that beef up your car security
If this all sounds a bit “spy movie”, don’t worry. You don’t need a panic room, just a few good habits:
- Always double-check your car is locked.
- Park in well-lit, visible spots.
- Consider a steering wheel lock or a tracker for added peace of mind.
- Store keys away from doors and windows, preferably in a pouch or tin.
Personally, after hearing that my neighbour’s car was swiped in the middle of the night without so much as a smashed window, I got myself a Faraday pouch that lives in a biscuit tin. Over the top? Maybe. But for the price of a takeaway, it’s a lot cheaper than replacing a stolen car.
A little trick with a lot of impact
So, if you’re still chuckling at the idea of storing your keys next to last night’s leftovers, remember — thieves aren’t laughing. These relay attacks are real, and they’re on the rise. Whether you go full microwave or opt for a safer pouch, blocking your key’s signal is one of those small actions that could make a very big difference.
Just don’t forget — never, ever turn on the microwave with anything metal inside. That hack could turn into havoc quicker than you can say “keyless entry.”
