An immobilizer is an electronic security device that is designed to prevent unauthorized operation of a motor vehicle. Immobilizers typically work by using a transponder, which is a small electronic device that is installed in the vehicle, and a coding device, which is usually a key fob or remote control. When the ignition is turned on, the immobilizer sends a signal to the transponder. If the transponder does not respond with the correct code, the immobilizer will prevent the engine from starting.

Immobilizers are a very effective way to deter car theft. In fact, studies have shown that immobilizers can reduce car theft rates by up to 80%. Immobilizers are also relatively inexpensive to install, and they can be added to most vehicles, even if they were not originally equipped with them.

There are two main types of immobilizers: mechanical and electronic. Mechanical immobilizers use a physical device, such as a lock, to prevent the engine from starting. Electronic immobilizers use a computer chip to store the vehicle’s unique identification code.

Mechanical immobilizers are less expensive than electronic immobilizers, but they are also less secure. Electronic immobilizers are more expensive, but they are also more secure.

If you are considering purchasing a new vehicle, it is a good idea to ask the dealer if the vehicle is equipped with an immobilizer. If the vehicle is not equipped with an immobilizer, you may want to consider having one installed.
