Description
OEM numbers A2208200375 and 2208200375, Mercedes-Benz, Mercedes-Benz W220 S-Class, rear left Keyless-Go antenna module Siemens 5WK4 831, genuine used and tested.
Fitted at the rear left of the W220 S-Class, this Siemens 5WK4 831 antenna covers the Keyless-Go detection zone at the rear left door, communicating proximity key presence to the Keyless-Go control module to allow touchless rear passenger-side entry without physical key operation.
Failure of this antenna causes the Keyless-Go system to lose detection coverage at the rear left door, so the proximity key is not recognised at that door and the passenger must use an alternative antenna zone or conventional key entry.
Supplied in good used condition, confirmed against OEM numbers A2208200375 and 2208200375 before dispatch. Fits Mercedes-Benz W220 S-Class. Professional installation is recommended. 14-day return policy applies.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
