Frankberg Door Lock Actuator Rear Left 6-pin

The essentials

This robust replacement door lock actuator is designed for the rear left passenger side of a range of popular hatchback and estate models. It provides reliable central locking operation and is intended for drivers looking to restore proper door control without the cost of a full lock assembly. With a 6 pin electrical connector, it mirrors the factory fit for straightforward installation and compatibility across multiple vehicle variants. By replacing a failing actuator, you can regain smooth locking and unlocking, improving convenience and security for day to day use. The component is built to endure regular use, offering a practical upgrade that supports long term durability in standard driving conditions. For many owners, it represents a sensible value option when a door lock unit has ceased to respond reliably.

Technical details

The actuator is positioned at the rear left passenger side and is compatible with a range of models including Golf IV variants, Passat saloon and estate, Leon, Toledo and Octavia of corresponding years. It is suitable for vehicles equipped with central locking systems and is sold with a reference range that includes 3B4839015AL and related part numbers. The design focuses on a simple plug and play replacement, helping to minimise downtime during installation. In everyday terms, this means you can restore keyless locking performance without extensive mechanical work, making it a practical choice for DIY enthusiasts and professional technicians alike. Delivery and fitment should be verified against the vehicle’s exact build and central locking configuration to ensure a precise match.

Benefits

You’ll notice a tangible improvement in locking reliability and remote operation, especially after repeated use of the power door lock mechanism. The 6 pin configuration ensures a solid electrical connection, reducing the risk of intermittent operation that can plague older actuators. As a replacement part, it’s designed to be durable and compatible with the central locking wiring loom found in many relevant models, helping to preserve original convenience and security features. This makes it a sensible value option for budget conscious repairs that still prioritise long term reliability. It also supports resale value by maintaining proper door functionality and user experience.

How to use it

Before fitting, verify that the vehicle is listed in the compatibility notes and that the central locking system is present. Disconnect the battery before starting to avoid any electrical hazards, then remove the interior door panel to access the actuator. Detach the wiring harness and fasten the new unit in the same orientation as the original component. Reconnect the loom, reassemble the panel, and perform a functional check to confirm smooth locking and unlocking. If there is any resistance or misalignment, recheck the mounting screws and electrical connections. This approach emphasises a straightforward replacement process and helps reduce vehicle downtime while restoring keyless entry performance. 🚗💨
