A car immobilizer, also known as an immobilizer, is an electronic security device that is designed to prevent unauthorized use of a vehicle. It works by disabling one or more of the vehicle’s systems, typically the engine or the fuel system, to prevent the car from starting or running.
Most modern cars come with an immobilizer as standard equipment. The immobilizer is usually activated by a small electronic chip that is embedded in the car key. When the key is inserted into the ignition, the chip sends a signal to the car’s computer, which verifies that the correct key is being used. If the key is not recognized, the immobilizer will prevent the engine from starting.
Immobilizers are an effective anti-theft measure because they make it much more difficult for thieves to steal a car. Even if a thief manages to gain entry to the car, they will be unable to start it without the correct key. As a result, immobilizers can help to lower the risk of car theft and can also lead to lower insurance premiums for car owners.
