Motorists with posh cars 'should leave keys in fridge to foil thieves'

It might sound completely bizarre, but according to security experts storing your car keys in the fridge is an effective way to prevent your vehicle from being stolen remotely.

The metal lining in kitchen appliances such as fridges and microwaves block potential thieves from intercepting the signals that are emitted by the fobs used to unlock and start "keyless" cars.

Keyless entry and start technology is becoming increasingly common on new cars, particularly on models from premium manufacturers such as Mercedes-Benz, BMW and Land Rover.

A common tactic among criminals is to position themselves near a house with a specialist device that can pick up and redirect the signals emitted by the keys to an accomplice, who then uses another transmitter to unlock the car and drive away.

The technique is becoming more and more prevalent, with one woman losing her Mercedes-Benz to thieves in Essex just last week.

Estate agent Paige Foster, 23, was shocked to discover her £35,000 vehicle had been stolen from her driveway while the keys remained on the kitchen bench in the house. CCTV footage shows one of the thieves holding a satchel that appears to contain a laptop up against a wall while another simply opens the car and drives away.

With the brazen technique becoming more common, motorists are being advised to take steps to ensure they are not affected in the same way. It is suggested they turn off their key fob's radio signal if they can, or by storing it in a container with a metal lining.

According to the Daily Mail, car crime levels are rising for the first time in 20 years as criminals find new ways to beat modern security systems. Another method sees thieves jam a fob's signal so it is prevented from locking the car's doors.

Andrew Miller, of vehicle security specialists Thatcham Research, told the newspaper: "As manufacturers address one weak point, criminals find others."
