Owners of luxury brands including Mercedes, BMW and Porsche targeted
Car thieves are buying kits that cost £19 online that enablethem to bypass car security systems and steal vehicles.
The crime had become so prolific that in August, Warwickshire police released a statement on the e90post forum warning BMW owners that 154 luxury cars had been stolen since January and to take extra precautions.
A BBC Watchdog investigation also found that the Metropolitan police were leaving warning leaflets under BMW windscreens.
Although the vehicles of choice are cars such as BMWs, Porsche and Mercedes, similar kits can also be bought for other makes of car, including Opel, Renault, Volkswagen and Toyota according to a report on Sophos' Naked Security blog.
Writer Lisa Vass said that if the video she had found online showing how the kit works was accurate it means that "even the village idiot could be behind the wheel of a fine ride with a $30 investment and a few minutes."
BMW has issued a statement saying people who are concerned "Can contact our Customer Service department on 0800 083 4397 or your local BMW dealer, either of which will happy to advise on next steps."
