What This Product Does

The lid forms the opening body panel over the rear engine compartment. It provides engine access while completing the surrounding rear bodywork when closed.

Functions

  • Covers the rear engine compartment.
  • Opens to permit engine inspection and maintenance.
  • Replaces a damaged or corroded engine-cover panel during restoration.

Technical Details

  • Supplied part reference: 64451200126.
  • Brand: OE Match.
  • Position: Rear.
  • Lock and hinges are not included.
  • The 356B / 356C installation diagram states that reworking is necessary.
  • Coupé applications are excluded; also excludes CARRERA GT.

Symptoms of Fault

Corrosion, impact damage or an earlier repair may leave the existing panel distorted or poorly aligned. Difficulty opening or closing the lid can also involve the hinges, catch or release mechanism, so inspect these separately before deciding which components need replacement.

Why Replacement Matters

A replacement lid can address panel deterioration or accident damage as part of bodywork restoration. Check the surrounding opening and supporting fittings at the same time, rather than relying on a new panel to correct worn hardware or previous body damage.

FAQs

Does this include the locking mechanism and hinges?
No. The diagram identifies the lid as supplied without these components.

Is this suitable for a coupé?
No. Coupés are excluded from the supplied application information.

Will fitting require adjustment?
The 356B / 356C diagram specifies reworking. Trial-fit and check panel alignment before final finishing.

Check fitment for your specific vehicle (model, year, engine) before ordering.

What the Rear Tailgate Lock Mechanism Does

The rear tailgate lock mechanism performs several important functions:

  • Secures the rear hatch in the closed position
  • Interfaces with the vehicle’s central locking system
  • Releases electronically via key fob or cabin switch
  • Maintains correct alignment of the rear lid
  • Ensures the vehicle remains weather sealed and secure

In Porsche 981 and 718 Cayman models, the rear hatch provides access to the rear luggage compartment. Proper lock function is critical for both security and usability.

Why Tailgate Lock Mechanisms Fail

Over time, rear hatch lock mechanisms can fail due to:

  • Electrical actuator motor wear
  • Internal gear or latch wear
  • Water ingress or corrosion
  • Repeated opening and closing cycles
  • Alignment stress on the latch
  • Wiring connector faults

Common symptoms of failure include:

  • Rear hatch not opening via remote
  • Tailgate not locking securely
  • Warning light indicating rear lid open
  • Intermittent locking operation
  • Hatch requiring manual force to close

Electrical actuator failure is particularly common as the vehicle ages and components experience repeated use.

When You Should Replace the Rear Tailgate Lock

You should consider replacing the rear tailgate lock mechanism if:

  • The rear hatch fails to lock or unlock electronically
  • The central locking system does not engage the rear hatch
  • The tailgate warning light remains illuminated
  • The latch makes clicking noises but does not operate
  • You experience intermittent operation
  • The hatch feels loose or insecure when closed

Prompt replacement ensures vehicle security, prevents accidental opening and maintains correct alignment of the rear lid.

Maintaining the integrity of your locking system protects your vehicle and preserves convenience and safety.

Key Benefits at a Glance

  • Direct replacement rear tailgate lock mechanism
  • Restores secure rear hatch closure
  • Fully compatible with central locking system
  • Fixes intermittent or failed latch operation
  • Suitable for Porsche 981 and 718 Cayman 
  • Ideal for repair and preventative maintenance
