How thieves can 'hack' into your car key - and why wrapping it in tin foil could help

It might sound a bit like a conspiracy theory, but car owner Kieran Bingham is advising others to wrap their keys in tin foil.

The software engineer discovered his car had been broken into by high-tech thieves using a fake wireless key fob.

The stealthy crime, known as a 'relay' attack, saw thieves break into Kieran’s 2016 Seat Leon on the night of Wednesday, April 12.

Kieran posted about the event on a local Facebook page and was instantly flooded with responses – he thinks there were at least eight similar attacks on the same night.

“We always lock our doors”

“It was on Thursday morning,” Kieran told the Bristol Post.

“I was putting my baby son in the car and my wife Keri asked if I had been in the car overnight.”

Kieran said no, but when the couple checked they found the glove box had been opened and items were scattered around the car.

“Everything was disturbed, luckily there wasn’t anything of high value in the car – they got away with £1.50 in change – so clearly a good night’s work for them,” said Kieran.

The family’s first thought was they maybe they had left their car unlocked and an opportunist had simply opened the door and gone through their things.

“But we are absolutely meticulous about locking our car because it folds the wing mirrors in,” Kieran explained.

"Someone is going round hacking wireless keys”

That left only one option. Luckily, as a software engineer Kieran was already aware of relay attacks.

He posted on his local area Facebook group saying: “Hackers can open your car using your remote fob while it's in the house. Has anyone else had someone snooping around in their car overnight?”

It turned out many of his neighbours had.

“The thread went crazy, we had over one hundred responses,” he said.

“I had private messages from people too – as far as I can tell this happened to at least eight other cars in the area, all on the same night.

“My thinking is someone is going round hacking wireless keys.”

Kieran did some research and explained that there were two different ways crooks can hack keyless cars.

What is a relay attack?

The first is a relay attack. This works on cars where the door opens automatically when the wireless key fob is nearby.

Normally the range of a key fob is between five and ten metres, but crooks can boost that signal with a clever bit of kit.

“They hold one end near the car and put the other end near to front door, to try and pick up the signal from the keys inside,” Kieran explained.

This boosts the range of the key fob signal, tricking the car into thinking the fob is nearby so it unlocks the door, when in reality the fob is still inside the owner's house.

“That’s why I’ve wrapped it in foil, to stop the device finding your keys,” explained Kieran.

He has now purchased a special “faraday ...
