Genuine OEM Nissan LH Front Door Lock Assembly – R32 / R33 Skyline & GT-R – 80503-70T00
Restore reliable factory door locking operation with the Genuine OEM Nissan Left-Hand Front Door Lock Assembly – 80503-70T00, a factory replacement component for compatible Nissan R32 and R33 Skyline models, including the BNR32 and BCNR33 Skyline GT-R.
Designed for the left-hand front door (passenger side on Australian right-hand-drive vehicles), this genuine Nissan assembly forms part of the original door latch and locking mechanism.
The front door locking system is responsible for securing the door and allowing the locking mechanism to operate correctly through the key, interior lock controls and factory central locking system where fitted.
After decades of use, original Skyline door locking components can develop mechanical wear, sticking mechanisms or operating faults that result in inconsistent locking and unlocking.
Replacing a worn or damaged assembly with the correctly specified genuine Nissan component helps restore the original locking arrangement and maintain factory-quality fitment.
Whether you're repairing a faulty passenger-side door lock, troubleshooting central locking problems or completing a detailed Skyline restoration, this genuine Nissan assembly is an excellent choice for maintaining original equipment functionality.

What Does the Front Door Lock Assembly Do?
The front door lock assembly forms part of the mechanism responsible for securing the door and controlling its locked or unlocked state.
On compatible R32 and R33 Skyline models, the assembly operates alongside the door handles, lock controls, mechanical linkages and central locking components where fitted.
When functioning correctly, the mechanism allows the door to latch securely and release through the intended factory controls.
Over time, wear or damage within the mechanism can result in sticking components, inconsistent locking or difficulty opening the door.
Replacing the faulty assembly with the correct genuine Nissan component helps restore the intended mechanical operation.
Common Signs of a Faulty Door Lock Assembly
- Passenger door intermittently failing to lock or unlock
- Locking mechanism becoming stiff or difficult to operate
- Door not releasing consistently from the interior or exterior handle
- Passenger-side door locking differently from the driver's side
- Worn or damaged internal latch components
- Unusual resistance during manual locking or unlocking
- Problems following previous door repairs or component removal
- Intermittent locking issues on vehicles equipped with central locking
Important: Similar symptoms may also be caused by faulty electrical actuators, wiring, central locking switches, door handle components or mechanical linkages. Diagnose the complete locking system before replacing individual components.
Factory Central Locking Compatibility
On compatible Skyline models equipped with factory central locking, the front door lock mechanism forms part of the overall locking system.
The system may include separate electrical actuators, control components, switches and mechanical linkages depending on the vehicle specification.
Correct operation depends on the condition and adjustment of all associated components.
Important: This listing is for the genuine Nissan door lock assembly identified by part number 80503-70T00. The inclusion of a separate electric actuator motor should not be assumed unless confirmed from the supplied assembly.
Replacing the door lock assembly will not necessarily resolve an electrical central locking fault caused by wiring, switches, control units or other components.
Ideal for R32 & R33 Skyline Restorations
The Nissan R32 and R33 Skyline ranges are now well-established classics, and many vehicles still retain their original door locking components.
After years of regular use, original latch assemblies can become worn, damaged or unreliable.
Replacing faulty components with genuine Nissan parts helps maintain the factory locking arrangement and original vehicle functionality.
This assembly is ideal for:
- BNR32 Skyline GT-R restorations
- BCNR33 Skyline GT-R restorations
- R32 and R33 Skyline Coupe repairs
- Compatible R32 and R33 Skyline Sedan repairs
- Replacing faulty passenger-side door lock assemblies
- Restoring original door latch operation
- Door replacement and accident repairs
- Refreshing ageing door mechanisms during restoration
- Maintaining genuine Nissan equipment
Installation Information
Before installation, confirm that the replacement assembly matches your vehicle's original left-hand front door locking arrangement.
Access to the locking mechanism generally requires removal of the interior door trim and associated components.
Carefully disconnect the relevant mechanical linkages and electrical connections where fitted, following the applicable Nissan workshop procedure.
Inspect the existing door handles, lock rods, retaining clips, wiring and associated components for wear or damage.
Install the genuine Nissan replacement assembly using the correct factory mounting points and applicable hardware.
Reconnect the original linkages and electrical connections, ensuring that all components are correctly secured and adjusted.
Before reinstalling the door trim, check the operation of the door latch, interior and exterior handles, manual lock controls and central locking system where fitted.
Safety Tip: Test the latch and locking mechanism with the door open before closing it. Incorrect linkage adjustment can prevent the door from reopening.
Professional Installation Recommended: Installation should be performed by a qualified technician familiar with Nissan door locking systems, particularly where linkage adjustment or central locking diagnosis is required.
