Take your keys - nearly 20% of all vehicles stolen have the keys in them
Park in well-lighted areas - car thefts occur at night more than half the time

Don't leave your car running, even for a minute - convenience stores, gas stations,    and ATMs are common hunting grounds for thieves
Completely close your car windows
Do not leave valuables in plain view
Do not hide a spare set of keys in the car - the pros know where to look
Park with your wheels turned toward the curb
Always use your emergency brake when parking
If you have a garage, use it - and when you do, lock both the vehicle and the    garage door
