What This Product Does

The latch forms part of the mechanical door-locking assembly, working with the door controls to retain and release the door. It is an internal mechanism rather than an exterior handle or key barrel.

Functions

• Provides the mechanical latching action within the door assembly.
• Works with the associated operating linkage during opening and locking.
• Replaces the corresponding internal mechanism during repair or restoration.
  
  

Technical Details

• Vehicle configuration: Left Hand Drive (LHD).
• 96453105301: Left door lock with antishutout mechanism; identified as /LL/L in the relevant 911 and 964 diagrams.
• 96453105400: Right door lock without antishutout mechanism; identified as /LL/R in those diagrams.
• The 964 diagram identifies separate Carrera RS and Speedster positions for both references.
  
  

Symptoms of Fault

Sticking door controls or inconsistent locking operation warrant inspection. These symptoms do not establish that the latch itself has failed: the operating linkage, handle and surrounding fittings should also be checked before choosing a replacement.

Why Replacement Matters

Renewing a confirmed worn or damaged latch addresses a mechanical fault within the door assembly. Selecting the correct side and mechanism specification is important because the two references are not identical. OE Match focuses on Porsche replacement applications, with reference matching and fitment evaluation forming part of its supplied development information.

FAQs

Is LHD the same as the door side?
No. LHD describes the vehicle configuration; Left and Right identify the individual door application.

Do both references have antishutout operation?
No. The supplied diagrams specify this feature for 96453105301, but not for 96453105400.

What should be checked before selection?
Compare the existing mechanism, reference number, door side and vehicle application, including the RS or Speedster specification where relevant.
