Help keep power door locking working as designed with the Standard Ignition Door Lock Actuator DLA-647. This electrically operated unit moves the door's lock mechanism when you press the power lock switch or use the remote. It is a direct-fit replacement for many Mercedes-Benz models, among them the 2009-2011 Mercedes-Benz SLK300, 2005-2011 Mercedes-Benz SLK350 and 2007-2009 Mercedes-Benz CLK550.
Signs this part may need replacing: a door that won't lock or unlock with the switch or remote, locks that work only intermittently, or buzzing or clicking from inside the door. If a failed actuator is the cause, DLA-647 is intended to replace it. Diagnose first, because fuses, wiring and switches can cause similar symptoms.
See the Buyer's Guide tab for engine specifics.
