On a cold winter morning it might seem like a good idea to start your car and let it warm up while you finish getting ready for work or school, but Durham police are warning people to be extra careful if they do this. Unattended cars warming up in driveways and parking lots are easy targets for car thieves. Every winter, Durham officers take several reports from people whose vehicles were stolen in this manner.

Additional car theft crime prevention tips:

• If you warm up your car, use a second key to lock the running vehicle.
• Never leave your keys in the car or ignition.
• Always roll up your windows and lock the car, even if it is in front of your home.
• Always park in busy, well-lighted areas.
• Install a mechanical device that locks to the steering wheel, column, or brake to prevent the wheel from being turned more than a few degrees.
• Investigate the purchase of an auto security system if you live in a high-theft area or drive a theft-prone vehicle.
• Carry your registration and insurance card with you. Don't leave personal identification documents or credit cards in your vehicle.
