Product Information

BMW Door and Window diagram for 318i, 325i

A door lock actuator is an electromechanical component in a vehicle that controls the locking and unlocking of the doors. It receives signals from the key fob, door switch, or central locking system and activates the locking mechanism to secure the door or allow entry. The actuator is typically found in each door and may also be part of the vehicle's overall security system.

• Inability to Lock or Unlock the Door: The most obvious sign of a failing door lock actuator is that the door cannot be locked or unlocked using the key fob or door switch
• Intermittent Locking Issues: The actuator may work sporadically, causing the door to lock or unlock inconsistently. You might hear clicking sounds without the door responding
• Door Lock Sticking: The actuator may cause the door lock to stick or jam, making it difficult to open or close the door

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
