'Keyless' car theft accounts for 42% of all vehicle thefts in London

"Thousands of cars from a host of manufacturers have spent years at risk of electronic car-hacking, according to expert research that Volkswagen has spent two years trying to suppress in the courts.
“Keyless” car theft, which sees hackers target vulnerabilities in electronic locks and immobilizers, now accounts for 42 percent of stolen vehicles in London. BMWs and Range Rovers are particularly at-risk, police say, and can be in the hands of a technically minded criminal within 60 seconds.
Security researchers have now discovered a similar vulnerability in keyless vehicles made by several carmakers. The weakness – which affects the Radio-Frequency Identification (RFID) transponder chip used in immobilizers – was discovered in 2012, but carmakers sued the researchers to prevent them from publishing their findings."
