[Overdrive]

Crono0001, it would be helpful to point out what year your car is, as there are slightly different methods depending on how old/young your car is.

I learned this just recently via some searching because the older (97-99 or maybe up to 2000) cars do not need as much dealer interaction if it's just something like a dead or recently replaced battery. You simply put the key into the door lock, then into the ignition, and you're back in action. Of course if the key has never worked for you then this may not apply. I know that the later cars required either a more involved process or simply had you forced to go to the dealer, but if it's that the key has not ever worked for you, it'll sadly require either the dealer or an independent Porsche specialist who has the right equipment for the job.
