New device lets car thieves 'clone' key fob signals

PITTSBURGH — Experts are warning drivers about a new way criminals can steal cars by hacking key fob signals.

The device allows tech-savvy thieves to break into vehicles that use keyless remotes and push-button ignitions.

The National Insurance Crime Bureau called the device – which is only about the size of a smartphone -- a “relay attack.” It works by essentially cloning the fob’s signals.

With permission, the NICB tested the device at a car dealership and officials were able to open 19 out of 35 vehicles. Officials were able to start all but one of the vehicles they got into.

The group said the trend shows automakers need to bolster cybersecurity in vehicles. Drivers with fobs are encouraged to park in crowded areas and alert police to suspicious people.

The Alliance of Automobile Manufacturers said enhancing security is a top priority for automakers.
