According to Landi, the vast majority of stolen vehicles were left unlocked with keys inside.
"Since this summer, we've seen an increase in Kia and Hyundai model vehicles where they've been targeted by these car thiefs due to a weakness in the ignition system. Unfortunately some of these car thiefs are not very sophisticated, they know generally how to do it but the problem is there's only certain makes and years of Hyundai's and Kia's that are suceptible to this problem."
Landi says people who own Hyundais and Kias should take extra precautions.
"We encourage people to, if you have a garage, park your car inside the garage, don't leave it out. If you have a secure parking lot, park it there. Someplace it's accessed controlled. I would strongly consider getting something like the Club or some type of device that can imobilize the vehicle, so even if they break the window they can't steal the car."
The Club is a steering wheel lock.
The Rock Island Police Chief says all car owners must continue to lock their car doors. He also says local police departments will soon begin their annual "Lock It Down" campaign.
