Those aren't factory keys.

Warranty voided. Tough luck pal.

I don't think any key fob was ever manufactured at Porsche AG. Therefore, the discussion is moot.
That thing probably came from Beverly Hills Motor Accessories or Automotion.

Good eye, no pcar key.

That'll buff right out.

It's a shame, as none of the mechanical updates seem to be installed...

I think there was a recall. Didn't you get it?

I could see this if it was water cooled .....but air cooled? Very rare.

Mine lasted just fine, until I added multiple keys.

Well at least it doesn't leak

I've got a call into Porsche North America about a possible good will repair. I have to say, I was really put off by some of the unprofessional comments from the lady on the phone. She didn't seem to feel my problem was serious enough to warrant opening a problem ticket in their system. Ferdinand would be rolling over in his grave if he knew how poorly I am being treated.

Maybe write a formal letter to the manufacturer.
