Modern vehicles (post-1995) use an immobilizer – an electronic security device that prevents the engine from starting unless the correct transponder key or fob is present. When a key is inserted, a coil around the ignition reads a chip in the key. The car’s ECU (Engine Control Unit) and immobilizer control unit verify a rolling code or fixed password. If the verification fails, the fuel pump, ignition, or starter is disabled.
IMMO Universal Decoding 4.5 is a professional automotive software tool designed to decode, remove, or repair the immobilizer (IMMO) code in a vehicle's Engine Control Unit (ECU).
