This simple hack can stop your keyless car from being stolen – and all you need is a drinks can

A CUNNING car owner has figured out a way to prevent keyless cars being easily stolen by storing fobs in an empty drinks can.

Wolverhampton-based Adam Farmiloe tested the theory with a Fanta, Coca-Cola and even a Carlsberg can whilst sitting in his Ford Fiesta ST.

The father of five was unable to start the keyless motor, as the aluminium blocked the signal from detecting the key.

When posting the YouTube video on Facebook group Stolen Cars Uk [sic], Farmiloe wrote: "I know people can be tight when it comes to car security even spending £5 on a Faraday pouch to stop relay attacks".

Named after British scientist Michael Faraday, these pouches - otherwise known as Faraday cages - distribute electrical charge and wireless signals around the bag, as opposed to reaching anything inside.

You can purchase a good signal blocker from £5 to £25, but the drinks can hack is a good substitute if you haven't got one to hand - although, it is not a sure solution for all vehicles.

Beyond his can trick, Farmiloe has also debunked the theory that putting a keyless fob into a microwave blocks the signal.

He carried his home microwave to his car - with the key inside - and successfully unlocked the Fiesta ST and started the ignition.

Meanwhile, around 30 cars are reported stolen every day - with the epidemic blamed on keyless technology.

Thieves can steal motors in mere seconds by using a cheap signal booster device outside a home to unlock and start cars on the driveway.

The car industry is yet to find a solution to these so-called relay attacks, beyond reverting to traditional keys.

And up to 95 per cent of car thieves are never identified by police, according to recent research by the Press Association.

Ford advised in a statement: "Do not store 'key-free' or passive key fobs just inside your front door within close range of a car parked outside.

"Instead, store further away, in a suitable metal box or shielded pouch available from Ford dealerships and which are TASSA (Tracking & Aftermarket Security System Association) approved."
