Genuine Mercedes Trunk Lock

Genuine Mercedes OEM Trunk Locks: Factory Precision for Your Mercedes-Benz

When the trunk on a Mercedes-Benz refuses to latch, release, or respond to the key fob, the culprit is almost always a worn or failed trunk lock assembly. Choosing Genuine Mercedes parts for this repair isn't just a matter of convenience — it's a matter of maintaining the tight engineering tolerances that define the Mercedes-Benz ownership experience. Unlike aftermarket alternatives, these are the same components that leave the factory floor on new vehicles.

What's Included in the Genuine Mercedes Trunk Lock Lineup

The trunk lock category covers several distinct components that work together to secure the rear compartment of your vehicle. Genuine Mercedes offers trunk lock actuator motors, trunk lid latch assemblies, trunk lock cylinders with keys, and remote-control closure mechanisms — each assigned a precise Mercedes-Benz part number tied to specific model years and body styles.

• Trunk Lock Actuator Motors — Electrically powered units responsible for engaging and disengaging the latch when triggered by the key fob, interior release button, or soft-close system. Some variants are designed specifically for trunks equipped with remote-control trunk lid systems and an additional lock mechanism.
• Trunk Latch Assemblies — Mechanical latch hardware that physically secures the trunk lid to the body. Genuine Mercedes latch assemblies include the latch itself and are sold as a complete unit for clean, straightforward installation.
• Trunk Lock Cylinders & Keys — Trunk lock cylinder and key sets are available for model years spanning 2019 through 2023 , ensuring late-model owners can restore full keyed-entry functionality to the trunk lid.
• Emergency/Manual Actuation Components — Certain Genuine Mercedes trunk unlock parts are mechanical in design, intended for manual emergency actuation — a critical safety feature if the primary electronic system fails.

Why OEM Is the Right Choice for Mercedes Trunk Locks

Genuine Mercedes-Benz parts fit your vehicle like no others can — they're engineered specifically to function with their fellow parts and systems, constructed from the finest materials available, and subjected to rigorous testing, meaning each part comes fully certified. For a trunk lock system that integrates with a vehicle's central locking, soft-close, and alarm systems, this level of precision matters far more than it might for a simpler mechanical component.

The trunk lock actuators offered under the Genuine Mercedes umbrella are manufactured specifically to fit Mercedes-Benz vehicles spanning model years from 1995 through 2023. Coverage extends across many of the brand's most popular platforms, including the C-Class (W204/W205), E-Class (W212/W213), CLS-Class, S-Class, and select AMG variants — meaning owners of both everyday drivers and high-performance models can find the right factory part.

Broad Model Coverage, Exact Part Numbers

One of the hallmarks of shopping Genuine Mercedes trunk lock components is the specificity of fitment. Each part carries an official Mercedes-Benz part number — such as 204-750-04-85 for C-Class and E-Class applications or 220-750-06-84 for S-Class platforms — eliminating the guesswork that often accompanies aftermarket purchases. Factory direct inventory comes with a minimum 12-month warranty , giving owners confidence in the longevity of their repair.

Whether you're dealing with a trunk that won't pop open from the key fob or a latch that no longer holds the lid securely closed, Genuine Mercedes trunk lock parts restore factory function without compromise.
