Compatibility

Land Rover Discovery 4 / LR4 – L319

* 2010–2016

* Rear Right Door

* O/S / Driver Side Rear on UK RHD vehicles

* RHD vehicles with Keyless Entry

* 5-door SUV

Applicable across selected Discovery 4 engine versions where the same locking specification is fitted, including:

* 2.7 TDV6 Diesel

* 3.0 TDV6 Diesel

* 3.0 SDV6 Diesel

* Selected petrol models

Engine size does not determine compatibility for this component. The vehicle’s locking system, keyless-entry specification and electrical connections are the important factors.

Additional Applications

The LR013890 / 8X2A-26412-AC lock family is also associated with selected Jaguar Land Rover applications.

Cross-reference data includes:

* Range Rover Sport L320 – selected 2010–2013 models

* Other Jaguar Land Rover applications using the identical lock specification

Fitment outside Discovery 4 should only be assumed when the original OE number, connector arrangement and vehicle equipment specification match.

Technical Information

This assembly incorporates the mechanical door latch and electrically operated locking actuator.

Functions include:

* Mechanically securing the rear door

* Electric central locking

* Lock/unlock actuator operation

* Interior door-handle release

* Exterior door-handle release

* Door locking status operation

* Keyless-entry system integration

* Safelock functionality where supported by vehicle specification

The actuator communicates with the vehicle’s locking/body electronics and operates the mechanical locking mechanism inside the door.

Keyless Entry / Central Locking Information

8X2A-26412-AC / LR013890 is associated with Keyless Entry applications.

The matching replacement specification is documented with:

10-pin connector + 4-pin connector

Discovery 4 vehicles were produced with different door-lock configurations, so a visually similar rear-right lock may not necessarily be electrically compatible.

Before purchasing, compare:

* Full OE part number

* 10-pin connector

* 4-pin connector

* Keyless Entry specification

* Rear-right mounting position

* Original lock design

Common Symptoms / Reasons for Replacement

A failing rear door lock actuator can cause:

* Rear right door failing to unlock

* Door failing to lock from the remote

* Intermittent central locking

* Door remaining locked while other doors unlock

* Keyless Entry not operating on the affected door

* Lock actuator clicking without releasing

* Door failing to recognise lock/unlock commands

* Interior or exterior handle release problems

* Door-open/closed status faults

* Complete electric actuator failure

Important Diagnostic Information

Before replacing the lock, check:

* Door wiring loom

* Electrical plugs and pins

* Wiring between the body and rear door

* 10-pin and 4-pin connections

* Door handle cables/linkages

* Mechanical latch movement

* Central locking operation

* Keyless Entry operation

* Relevant vehicle fault codes

Broken wiring or damaged connectors can produce symptoms similar to a failed door-lock actuator.

Installation

The mechanism is mounted internally within the rear right door.

Installation generally requires removal of the rear door trim and access to the internal handle, cable/linkage and electrical connections.

After installation, check:

* Exterior handle operation

* Interior handle operation

* Central locking

* Keyless Entry

* Door opening and closing

* Mechanical latch operation

All connectors and cables should be correctly secured before the door trim is refitted.

Programming / Coding

When replacing an identical lock actuator with the correct OE specification, the lock mechanism itself normally does not require separate programming or coding.

However, diagnostic fault codes should be checked and cleared where necessary after installation.

Important Compatibility Note

Please match the complete part number 8X2A-26412-AC / LR013890 with your original unit before purchasing.

This version is intended for the appropriate RHD Keyless Entry locking system and uses 10-pin + 4-pin electrical connections.

Cross-reference numbers including 8X2A-26412-AE, LR077828 and LR091345 belong to the associated replacement/reference family, but always compare the original number and connector configuration before ordering.

Do not purchase solely by vehicle model and year because Discovery 4 door-lock specifications can vary according to factory equipment.

Genuine used Land Rover OEM part.

Normal signs of previous use, removal and storage may be present.
