This tailgate lock machine is a direct replacement part for the luggage compartment lid lock on your Nissan Qida. When the original lock fails, it can leave the boot insecure or the lid stuck closed. This replacement lock restores factory-level locking function and secure access to your trunk. It is designed to match the OEM specifications of your vehicle, using reference numbers 84631ED40A, 84631-ED40A and 84631-ED400 for accurate fitment. The lock assembly is supplied as a single piece, ready for installation by a professional mechanic. Ideal for restoring the convenience and security of your car's boot without replacing the entire tailgate assembly.

Features and Construction

This lock machine is built to the same form and function as the original Nissan part. It is a simple, reliable mechanical and electrical unit that controls the latching of the boot lid.

Material and Build

The lock mechanism uses metal and high-grade plastic components consistent with automotive interior parts. It is designed for long-term use in the door panel environment, resisting wear from repeated opening and closing. The default finish matches the factory colour of the original lock assembly.

Size and Practical Fit

Dimensions are identical to the OEM part for the Nissan Qida, ensuring that it fits into the existing mounting points in the boot lid. No modifications to the vehicle body or wiring are necessary for a correct installation. The lock actuator includes the electrical connector that mates with the car's central locking system.

Uses and Placement

This replacement lock is designed exclusively for the rear boot lid on compatible Nissan vehicles. It is most commonly used on the Nissan Qida but may also fit other models with the same lock design.

Vehicle Fitment

The lock is specifically listed for the Nissan Qida. Always confirm your vehicle's compatibility using the supplied OEM part numbers: 84631ED40A, 84631-ED40A, or 84631-ED400. Check the shape of your original lock and mounting bolts before purchasing to ensure a match.

Installation Context

This lock is intended for the rear luggage compartment. It is not designed for side doors, glovebox, or ignition. Replacing only the lock machine preserves the original handle and trim, saving time and cost compared to replacing the entire boot latch assembly.

Benefits and Buying Value

Choosing this replacement lock offers a straightforward solution to a common failure point on older or high-mileage Nissan Qida vehicles.

Reuse and Low Maintenance

Once installed, the lock requires no routine maintenance beyond occasional lubrication and cleaning of the latch mechanism. It is a sealed unit that functions smoothly for years under normal use.

Why Choose This Product

This part is a direct OEM-style replacement. It restores full functionality of your boot lock without unnecessary extras, and it is available at a reasonable price compared to dealership alternatives.
