0205455632 Mercedes W202 W210 Vito Immobilizer Module – OEM Used & Tested

Opis

This Mercedes immobilizer module is a genuine OEM electronic control component for the Mercedes W202, W210 and Vito models. Primary OEM number 0205455632. It is designed to read the coded signal of the ignition key and to release the engine start only when the key is recognized as valid, protecting the vehicle against theft.

Its job is to communicate with the transponder in the ignition key through the antenna ring and to exchange the security code with the engine control unit before the starter and the fuel system are enabled. A properly working immobilizer module supports reliable engine start with a valid key, effective protection against unauthorized starting and correct operation of the vehicle security system.

Common signs of a faulty unit include an engine that cranks but does not start, a key that is not recognized, a security or immobilizer warning light that stays on or blinks, a vehicle that starts only at times or stored fault codes for the key reader or the data link. When the module fails, the engine may be blocked completely and the vehicle may have to be recovered to a workshop.

This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 0205455632 before ordering and compare it with the number on the label of your unit. Professional installation is recommended, and a diagnostic scan, key and control unit synchronization, adaptation or coding where applicable are required after installation, because the module is linked to the security system of the vehicle.
