Leave your car doors unlocked
This may sound like a no-brainer, but many auto thefts happen when people forget to lock their doors. A locked door is the first line of defense.
"About 50 percent of cars stolen are left unlocked and sometimes have the keys in the ignition," says Staton.
Most car thieves won't bother breaking into a locked car when there are so many unlocked autos to choose from, says Frank Scafidi, spokesperson for the National Insurance Crime Bureau (NICB).
