The website PetrolPrices.com, analysing the data, says thieves are using high-tech gadgets, reports the Evening Chronicle.
The site says: âA shocking 85,688 cars have been reported as stolen this year.
âThatâs 30% more than the 65,783 reported in 2013, according to data collected by the RAC.
âMany of the more recent thefts are due to gangs using gadgets to gain access to vehicles, often on demand so they can be sold on.â
PetrolPrices.com says thieves have been using locking jammers and relay boxes.
âIf your car is on this list, donât panic,â the site adds.
âKeep your car key away from your front door in a metal box, metal safe, metallised signal blocking pouch, microwave, or fridge.
âFit a tracking device to your car
âInvest in a steering wheel lock, which acts as a visible deterrent.â
Locking jammers block the signal coming from the key when the driver locks the door.
This means that the car remains unlocked, making it easy for the thieves to enter the vehicle.
Meanwhile, relay boxes scan houses for key signals. They then transmit these to another box close to the car. The result is that the car responds as though the key is unlocking it.
Putting the keys in a metal box, or in the microwave or fridge, stops the signal from the thievesâ device from getting through.
