Recently purchased 2005 Carrera 4S.  Key fob was working but suddenly stopped.  Light still flashes but will not lock/unlock doors.  Second key fob still works so system seems to be ok.  Any suggestions?

Reverse the battery - press the button once.

Replace the battery in the correct orientation and try again.

 

If that does not fix it then you likely need a new key fob (and the $150 programming to your car).

I know this sounds a little rudimentary , but have you tried replacing the battery? Also, you might need to reflow the connections on the key fob's circuit board. If that doesn't work, then you should be prepared to replace it. I wouldn't advice owning these cars with just one working key fob. Could get expensive if you lose you one and only key fob when the car is armed. You end up having to replace the immobilizer on top of new keys.

Similar problem with my MY2000.  First key failed last summer, 2nd key in December.  Both still started the car and manually locked/unlocked.  Fob lights flash once, no longer flicker even after battery replacement and polarity swapping.

 

Finally bought a new fob from PorscheParts.US for $160 delivered and found local indy to program for $68.  Probably should have bought 2 keys at the same time as programming appears to be a flat fee with most the places I talked to.
