Introduction to Immobilisers
An immobiliser is an electronic security device fitted to a vehicle that prevents the engine from running unless the correct transponder key (or other authorization device) is present. This system is designed to deter vehicle theft by ensuring that even if a thief manages to enter the vehicle and hotwire the ignition, the engine will not start without the proper key. Immobilisers have become a standard feature in the automotive industry, significantly reducing vehicle theft over the years.
How Immobilisers Work
Immobilisers work based on a simple yet effective principle. When the ignition is turned on, the vehicle’s computer (ECU) sends out a signal to the immobiliser, which then communicates with the key’s transponder. The transponder in the key responds with a unique code that the immobiliser recognizes. If the codes match, the immobiliser allows the engine to start. This process happens almost instantaneously and is a critical part of vehicle security.
