COMPATIBILITY

Renault Megane MK3 / Megane III Coupé – DZ0/1_

Confirmed application:

• 2008-2016 Megane III Coupé depending on production date and specification

• 3-door Coupé only for this application

• Front right door

• O/S / driver’s side on UK RHD vehicles

• Petrol and diesel models depending on specification

• Manual and automatic transmission models where corresponding locking system is fitted

Direct used-part records confirm 805020004R on the Megane III Coupé DZ0/1_ 3-door platform. (B-Parts)

CONFIRMED ENGINE APPLICATIONS

Direct vehicle records show this lock fitted to selected:

1.5 dCi

• Megane III Coupé 1.5 dCi

• K9K engine family

• K9K836 application documented

• 110 PS / 81 kW application documented

The lock is a body/electrical component, so compatibility is not determined solely by engine size.

Other petrol and diesel Megane III Coupé models may use the same lock where the 805020004R locking configuration is fitted.

3-DOOR COUPÉ INFORMATION

This listing is specifically for the:

Renault Megane III Coupé – DZ0/1_ – 3 Door

The Coupé has a different door/body configuration from the Megane III 5-door Hatchback and Grandtour/Estate.

For this reason, buyers should not assume a front-right lock from a 5-door Megane III is automatically interchangeable with the Coupé mechanism.

Matching the OE number and physical mechanism is strongly recommended.

RIGHT-HAND / UK VEHICLE SIDE

This mechanism is fitted to the:

Front Right Door

For a UK right-hand-drive vehicle:

O/S = Offside

Front Right = Driver Side

OSF = Offside Front / Driver Front

Therefore, this is correctly described for the UK market as the:

Driver O/S Front Door Lock Mechanism

TECHNICAL INFORMATION

The 805020004R lock mechanism is installed inside the front door and forms part of both the mechanical latching and central-locking systems.

Its functions include:

• Holding the front door securely closed

• Locking and unlocking the door

• Operating with the vehicle’s central locking system

• Releasing the door when the interior or exterior handle is operated

• Providing the mechanical latch connection with the body-mounted striker

• Allowing manual emergency locking where applicable

• Interfacing with the door’s electrical locking system

Renault’s Megane III operating information also shows a manual emergency locking provision for the front-right door, which is part of the vehicle’s door-locking arrangement. (Renault User Manual)

CENTRAL LOCKING SYSTEM INFORMATION

The complete Megane III door-locking system works through several components, including:

• Door lock / latch mechanism – 805020004R

• Exterior door handle

• Interior door handle

• Central locking electronics

• Door wiring loom

• Renault Card / keyless locking system where fitted

• Door striker

• Associated cables and linkages

Depending on specification, some Megane III Coupés can have additional locking/security functionality.

A documented 805020004R Coupé unit is specifically identified as a right front central-locking door lock with additional locking functionality. (B-Parts)

COMMON SYMPTOMS OF A FAULTY DOOR LOCK

Replacement may be required if:

• Driver door will not lock

• Driver door will not unlock

• Central locking works on other doors but not the driver’s door

• Door intermittently fails to unlock

• Door will not latch correctly

• Door appears closed but does not securely latch

• Exterior handle operates but door remains locked

• Interior handle fails to release the door

• Central locking actuator becomes noisy

• Lock mechanism sticks or jams

• Door-open / locking status behaves incorrectly

• Mechanical latch is damaged

• Lock damaged following accident or door repair

IMPORTANT DIAGNOSTIC INFORMATION

A door that will not lock or open does not automatically mean the lock mechanism has failed.

Before replacement, inspect:

• Door wiring loom

• Electrical connector

• Power supply to the lock

• Exterior handle mechanism

• Interior handle / cable

• Door striker alignment

• Central locking system

• Renault Card / keyless system where fitted

• Associated fuses and control electronics

• Diagnostic fault codes where applicable

If the other doors operate normally through central locking but the front-right door consistently fails, the door lock/actuator mechanism becomes a particularly relevant component to inspect.

IMPORTANT PART NUMBER INFORMATION

Primary Renault OE reference:

805020004R

This number is directly documented as:

Front Right Lock – Renault Megane III Coupé (DZ0/1_) – 3 Doors

A corresponding Coupé unit carrying 805020004R is documented on a 2011 K9K836-powered Megane III Coupé. (B-Parts)

PART NUMBER VARIATIONS

Be careful when comparing similar Megane III locks.

For example, 805020003R is also documented on front-right Megane III Coupé locks in certain configurations. (B-Parts)

This means the last digits/revision of the OE number can matter, potentially reflecting differences in locking equipment or production specification.

Do not automatically assume 805020003R and 805020004R are interchangeable without confirming the vehicle specification.

INSTALLATION

Installation requires removal of the front-right interior door trim and access to the internal door-lock assembly.

During installation:

• Disconnect electrical connections carefully

• Inspect the wiring and connector

• Inspect interior/exterior handle linkages

• Check the door striker

• Install the replacement lock correctly

• Confirm all mechanical linkages are correctly attached

• Test interior handle operation

• Test exterior handle operation

• Test central locking

• Confirm the door latches securely

The door should be fully tested before refitting all trim panels.

PROGRAMMING / CODING

Programming Required: Normally No

Coding Required: Normally No

A like-for-like replacement mechanical/electric door-lock assembly normally works through the existing vehicle central-locking system.

However, the replacement unit must have the correct electrical and locking configuration for the vehicle.

IMPORTANT COMPATIBILITY NOTE

Before ordering, please compare:

805020004R

and check:

• 3-door Coupé body style

• Front right position

• O/S / driver’s side on UK RHD vehicle

• Electrical connector

• Connector pin configuration

• Lock mechanism shape

• Cable / linkage mounting points

• Central locking specification

• Keyless / hands-free equipment where applicable

• Production date

• Listing photographs

Do not rely solely on “Renault Megane MK3” when ordering.

The Megane III range includes Coupé, Hatchback, Estate/Grandtour and Cabriolet variants, and different lock references/configurations were used.

For the safest compatibility check, match the OE number and complete physical/electrical configuration with the original lock.

CONDITION

Used Genuine Renault Part.

Normal cosmetic marks, dirt and signs of previous installation may be present.

Please inspect all listing photographs carefully for the exact condition, electrical connector, mounting points, linkages and identification numbers.
