A hood lock prevents a thief from stealing parts under the hood or disconnecting anti-theft devices.
When turned on, this mechanism stops the flow of fuel from the fuel pump so the car will only go a short distance and then quit.
Time Delay Switch
This is a power cut-off device which, unless a switch is turned off, will disable your car shortly after it's started.
Time Delay Ignition
This device will activate your ignition only after a preset time has passed. There is no way to activate the ignition before the preset time has elapsed.
Clutch and Brake Lock
This mechanism, used only on manual transmission vehicles, locks the brake pedal and the clutch pedal together so one can't be operated without the other.
Brake Lock on Hydraulic System
This is a mechanism which, when activated, locks on all four brakes and makes it difficult to move or tow the car, even if the engine is started.
Bar locks attach to the steering wheel and block the ability to steer the vehicle. They can also stop the theft of the air bag. This tool can be enhanced with the use of a shield that makes it more difficult to cut the steering wheel and remove the bar lock.
Wheel locks are an inexpensive way to prevent the theft of your vehicle's wheels and tires.
Locking Gas Cap
A locking gas cap prevents thieves from stealing the gas or refilling the gas tank if they steal the vehicle. For added convenience, many of the locking gas caps with combination access also provide a locked place to hide the vehicle's extra set of keys.

Etching the Vehicle Identification Number (VIN) into your window glass is a way of keeping the vehicle from being stolen for the glass parts.

More expensive alarm systems can include:
Remote control of the vehicle: If the driver does not enter a code before starting, the alarm company is alerted and tracks the vehicle. With this system, the police can shut off the vehicle so the thieves can't escape. It also allows the owner to call the alarm company and shut off the car in case of a carjacking.
This technology allows the owner to call and have the door opened or the vehicle started anywhere in the world.
It will tell you where you are within 10 feet of your exact location and give you directions on how to get to your destination.
