Descriere
This Mercedes-Benz immobilizer module (WFS) is a genuine OEM electronic component for the Mercedes W210 E-Class. Primary OEM number 2108202726. It is designed to act as the anti-theft control unit of the vehicle, reading the coded signal of the ignition key and comparing it with the stored data before it allows the engine to start.
Its job is to communicate with the key transponder and the engine control unit, and to release the starting function only when the key is recognized as valid. Without a correct match, the engine will not run, which blocks unauthorized starting. A properly working immobilizer module supports reliable key recognition, secure vehicle protection, and correct operation of the starting and anti-theft system.
Common signs of a faulty unit include an engine that cranks but does not start or does not crank at all, a key that is not recognized, an immobilizer or key warning light in the instrument cluster, intermittent starting problems, and fault codes stored in the system memory. When the module fails to authorize the key, the engine may be blocked even though the battery, starter, and fuel supply are in good condition.
This is a used original part, removed from a vehicle and tested before sale. Match the exact OEM number 2108202726 before ordering. Professional installation is recommended, and key matching, coding, or adaptation with a diagnostic tool is usually required where applicable, because the module is paired to the keys and control units of the vehicle.
