An official with the Cheyenne Police Department is warning people not to leave their vehicles unlocked and unattended while warming them up.

Captain Mitch Maxwell says such cars are the number one target for car thieves in Cheyenne.  Maxwell says most newer cars have an "auto start" feature, which starts the car without a key. But if someone tries to drive off without the key, the car stalls.

Maxwell says if you don't have auto start, you should  lock your warming vehicle and use key less entry to get in. The other option is to simply get an extra car key and lock up your warming vehicle, using the spare key to get in.

Local police have also issued repeated warnings against leaving non-running cars unlocked, especially if they have guns or other valuables.
