COLORADO SPRINGS, Colo. -

A warning for drivers: if you use keyless entry to get into your car, hackers have caught on and are ready to strike.

“I wouldn’t say that malls would necessarily be bigger targets because the cars are pretty transient,” said Craig Smith, chief investigator for Bright Star Investigations. “Cars that are going to be parked for quite some time to give the hacker time on target to evaluate.

When you lock your car with a key fob, it sends out a signal so you can get inside. But a hacker could be watching and receiving the signal. If they get it, they can control your car just as easily as you could.

“I think it takes a bit to set up. It’s not something that can be done over a weekend. You have to be a pretty serious to know what you’re doing,” Smith said.

The solution: Lock your car internally or manually with a key that’s not electronic.

It costs about $1,000 for a hacker to get the right antenna and receive that signal.

But as technology expands, this type of hack will get easier and cheaper for tempted crooks.

“Hacking has always evolved over the years. I think there’s definitely a possibility for it to happen. But I don’t think it’s an imminent danger, but sure, it could definitely happen,” Smith said.

Colorado Springs police are aware of these crimes but don’t have any active cases.

Hackers typically break in through this method to steal anything inside the car.

Tech experts said the hackers rarely steal the car, because this method makes it much more laborious.
