Susceptibility to keyless ‘relay attacks’ has resulted in ‘Poor’ security ratings for the DS3 Crossback, Mazda 3, Toyota Rav-4 and Volvo S60, in Thatcham’s latest round of testing.

In March this year, the Ford Mondeo, Hyundai Nexo, Kia ProCeed, Lexus UX, Porsche Mecan and Toyota Corolla, were also rated as ‘Poor’, due to their lack of protection against theft from keyless entry manipulation.

Richard Billyeald, chief technical officer at Thatcham Research, said: “Theft claims paid by insurers in the first quarter of this year were at their highest for any quarter since 2012, with a payment made to a car crime victim every eight minutes. These figures demonstrate why the automotive industry must move to secure keyless entry/start systems, many of which offer criminals the chance to quickly and silently circumvent otherwise robust physical security.”

Of the seven new cars tested, four have keyless entry/start systems susceptible to the Relay Attack and have therefore been rated Poor – whether optional or standard.

However, were it not for the keyless entry / start vulnerability, all the cars assessed would have earned a Good rating or better, according to Billyeald.

Manufacturers including BMW, Porsche, and Ford have recently introduced fixes to secure vulnerable keyless entry / start systems; with Ford recently introducing a new, more secure fob for its latest Fiesta and Focus model ranges.
