An immobilizer, also known as an immobiliser, is an electronic security device fitted to a motor vehicle that prevents the engine from being started unless the correct key is present. It acts as an anti-theft mechanism and is designed to prevent the vehicle from being "hot wired" after entry has been achieved, thereby reducing motor vehicle theft. Here are some key points about immobilizers:
-
Function: An immobilizer prevents the engine from starting due to an improper ignition key. It works by utilizing variations of radio waves as a key identity on the vehicle. Only the correct key or fob can activate the system and start the engine.
-
Components: The main components of an immobilizer include the transmitter, transponder, and theft different system. The transmitter sends radio waves with a certain frequency to the control module, the transponder receives radio wave signals sent to the control module for identification, and the theft different system ensures the security of the vehicle.
-
Types: There are two main types of car immobilizers: passive and active. A passive immobilizer system activates itself automatically when the ignition is turned off, while an active immobilizer must be intentionally turned on.
-
Effectiveness: Research has shown that the uniform application of immobilizers reduced the rate of car theft by 40%.
-
Installation: Installing a car immobilizer is not a trivial task and requires a certain level of comfort with a vehicles electronic systems.
In summary, an immobilizer is a crucial security feature in modern vehicles, effectively preventing unauthorized use and reducing the risk of theft.
