Also shares components with Mercedes-Benz R170 SLK230/SLK320/SLK32 AMG (2001–2004) — verify before cross-application⚠️ Why buy this as a set: The Crossfire's immobilizer system pairs the ECM, SKREEM module, and ignition key together — mismatched individual parts typically will not start the car without specialized programming. Because these came from the same vehicle, they are already matched to each other. Some programming/setup to your specific VIN may still be required — please research your specific situation or consult a specialist before purchasing.Condition Notes:
