Researchers say they have figured out how to use remote entry to hack other people's vehicles. And 100 million Volkswagons are at risk.

Though keyless entry is very convenient, a team of security experts say it is also very risky.

They have figured out how to use remote entry to hack other people's vehicles by essentially cloning the key, unlocking the person's vehicle and driving away.

They also say that about 100 million Volkswagons made over the last 21 years are at risk of this hacking. Other car brands, including Chevrolet, also have the potential of being hacked.

ABC6 reports that these researchers are planning to present their new findings at a security conference on Friday.
