Why Replace This Part?
Door lock knob surrounds are small but visible interior trim pieces. Over time, they can become scratched, cracked, faded, loose or missing, especially on older Porsche models where door cards may have been removed for lock, handle, speaker or window regulator repairs. Replacing the surround with a Genuine Porsche door lock knob surround helps restore the correct factory look and prevents the door lock knob area from appearing unfinished or worn.

Common Symptoms of a Worn or Missing Surround
•  Missing trim around the door lock knob
•  Cracked or broken surround
•  Loose or poorly seated door lock trim
•  Scratched or faded interior trim
•  Door card opening visible around the lock knob
•  Mismatched or incorrect aftermarket trim
•  Interior restoration requiring correct finishing parts
•  Damage after previous door panel removal.

When to Replace This Part
•  During door panel restoration
•  When replacing interior door trim pieces
•  If the original surround is cracked, missing or loose
•  After door lock, latch or handle repairs
•  During electric window or door card service
•  When restoring a Porsche interior to factory condition
•  If the door lock knob area looks unfinished or worn
•  When replacing non-original or damaged trim with Genuine Porsche parts.

Where It Fits on the Car
This part fits on the interior door panel around the door lock knob / door locking pin area. It provides the finishing surround for the lock knob aperture. Correct fitment helps the door lock knob sit neatly within the trim and maintains the original Porsche interior appearance.
