 7,000 who left the keys in their vehicle and had it stolen, a 22% increase in just a year. Old habits die hard and thieves can't help themselves, especially when it's so easy. So why is it so difficult for some people to turn off the car, take the key or the fob and lock it up before they walk away? Turn off the ignition and lock your vehicle every time you get out. Don't leave keys or fobs inside. Put all valuables out of sight in the trunk or take them with you.
