The cars that never return are driven or shipped out of the country, stripped by chop shops, and sold piece by piece or retagged and resold to unsuspecting people. Some owners even hide or destroy their own cars to collect the insurance money. The insurance industry carries on numerous other activities designed to make you and your possessions more secure. A vehicle's make affects the probability of its being stolen. Security devices may reduce Auto insurance premiums, too.
Carriers distinguish between active and passive alarm types.
Engine-disabling systems, which cut off the gas supply or interfere with the engine's electronic controls. Tracking devices, which allow services or the police to locate a stolen car. Use the locks you have. Always lock up your home when you go out, even if it's only for a few minutes. Secure sliding glass doors with commercially available bars or locks, or put a wooden dowel or broomstick in the door track.
