Door Handle Return Spring.
The Porsche Door Handle Return Springs are genuine OEM components designed to restore smooth, reliable operation of your exterior door handles. These springs provide the necessary tension for the handle to return to its flush position after being pulled, ensuring proper door function and a clean factory appearance.

Fits:
  • Porsche Boxster 987 2.7L 2005 -08/08
  • Porsche Boxster 987 S 3.2/3.4L 2005-08/08

  • Porsche Cayman S 3.4L 987C 2005-08
  • Porsche Cayman 2.9L 987C MKII 2009-12

  • Porsche 997 MKII Turbo 2010-13
  • Porsche 997 MKII GT2 RS 2011-13

What This Product Does:

Provides the necessary tension so that when you pull the door handle, it springs back (returns) to its original (closed) position smoothly. Without this spring, the handle may stay partly pulled, feel loose, or not return reliably.
Keeps the handle flush with the door panel when not in use, which helps maintain appearance, prevents water ingress, reduces noise, and keeps the locking mechanisms operating properly.

Symptoms Of A Worn Or Broken Return Spring:

  • Handle does not fully return to closed position 
  • Loose or floppy door handle feel  
  • Increased risk of water / dirt ingress behind handle area  
  • Rattling or noise from handle area over bumps  
  • Difficulty locking or closing the door from outside

Why Replacement Matters: 
  • Restores proper function of the door handle: ensures smooth operation and that the handle returns to flush, sealed position.
  • Prevents cosmetic and water-damage issues: handle sticking out or being loose can let in water, trap dirt, damage finish.
  • Improves safety and reliability: ensuring doors close properly, especially in wet or cold conditions.

This mechanism works with the vehicle’s central locking system and door latch hardware to ensure secure door closure, correct electrical unlocking and reliable function every time you enter or exit the vehicle.

What the Front Passenger Door Lock Mechanism Does

The door lock mechanism is an essential component of your Porsche’s door security and access system. It performs key functions such as:

  • Securing the front passenger door when locked via key fob, interior switch or automatic lock
  • Engaging and releasing the latch during door opening and closing
  • Communicating with central locking to synchronise all vehicle doors
  • Ensuring proper alignment between the door and striker plate
  • Maintaining weather and vibration-resistant closure

In modern Porsches, this mechanism often includes electronic actuation combined with mechanical latch elements, ensuring responsive and quiet operation.

Why Door Lock Mechanisms Fail

Door lock mechanisms can wear out or malfunction due to both mechanical and electrical factors:

  • Actuator motor fatigue from frequent use
  • Internal gear wear and plastic component degradation
  • Corrosion or water ingress over time
  • Misalignment or sagging from hinge wear
  • Wiring or connector failure in central locking circuits
  • Physical stress from rough operation or impact

Common signs of a failing door lock mechanism include:

  • Door not locking or unlocking reliably with key fob or interior switch
  • Door stays locked/unlocked intermittently
  • Unusual clicking, grinding or buzzing noises when locking/unlocking
  • Alarm triggering without cause
  • Door not latching securely when shut

Because this mechanism works closely with the vehicle’s central locking and alarm systems, failures can impact security, convenience and peace of mind.

When You Should Replace It

You should consider replacing the front passenger door lock mechanism if:

  • You experience intermittent or failed locking/unlocking
  • The door won’t latch securely or opens unexpectedly
  • The central locking system shows fault codes related to door circuits
  • Audible actuator noises occur without door action
  • You are repairing a vehicle that has been water-damaged or has corroded lock parts

Prompt replacement restores proper security, consistent lock performance and seamless integration with your Porsche’s locking and alarm systems.

 Key Benefits at a Glance

  • OEM-equivalent replacement door lock mechanism
  • Restores secure front passenger door locking
  • Compatible with central locking systems
  • Eliminates intermittent or failed lock action
  • Suitable for multiple Porsche models (Macan, Panamera, 718, 981, 991, Cayenne)
  • Improves convenience, security and reliability

  • Porsche 981 Cayman GT4 – with option Code 534

Diagram Ref No 14

This mechanism works with the vehicle’s central locking system and door latch hardware to ensure secure door closure, correct electrical unlocking and reliable function every time you enter or exit the vehicle.

What the Front Passenger Door Lock Mechanism Does

The door lock mechanism is an essential component of your Porsche’s door security and access system. It performs key functions such as:

  • Securing the front passenger door when locked via key fob, interior switch or automatic lock
  • Engaging and releasing the latch during door opening and closing
  • Communicating with central locking to synchronise all vehicle doors
  • Ensuring proper alignment between the door and striker plate
  • Maintaining weather and vibration-resistant closure

In modern Porsches, this mechanism often includes electronic actuation combined with mechanical latch elements, ensuring responsive and quiet operation.

Why Door Lock Mechanisms Fail

Door lock mechanisms can wear out or malfunction due to both mechanical and electrical factors:

  • Actuator motor fatigue from frequent use
  • Internal gear wear and plastic component degradation
  • Corrosion or water ingress over time
  • Misalignment or sagging from hinge wear
  • Wiring or connector failure in central locking circuits
  • Physical stress from rough operation or impact

Common signs of a failing door lock mechanism include:

  • Door not locking or unlocking reliably with key fob or interior switch
  • Door stays locked/unlocked intermittently
  • Unusual clicking, grinding or buzzing noises when locking/unlocking
  • Alarm triggering without cause
  • Door not latching securely when shut

Because this mechanism works closely with the vehicle’s central locking and alarm systems, failures can impact security, convenience and peace of mind.

When You Should Replace It

You should consider replacing the front passenger door lock mechanism if:

  • You experience intermittent or failed locking/unlocking
  • The door won’t latch securely or opens unexpectedly
  • The central locking system shows fault codes related to door circuits
  • Audible actuator noises occur without door action
  • You are repairing a vehicle that has been water-damaged or has corroded lock parts

Prompt replacement restores proper security, consistent lock performance and seamless integration with your Porsche’s locking and alarm systems.
