Key reprogramming

[Hank]

I just learned from my service representative that I have to leave my car (C2S - 2007) for two hours to have the keys reprogrammed. Why? Because I left one in the same suitcoat pocket as the security pass for the building in which I work. He also told me that Porsche is aware of the problem and has fixed it for newer cars. Is this legit? Is there any way to do it myself?

Thanks. Hank

Not really.

Reprogramming a key requires:

All keys (so you don't program over an active one)

Your car because the code(s) get put in the immobilizer control module

Your car's specific IPAS security codes from Porsche AG.

and, if you get a new key the, the new key and 24 digit code exclusive to that key.

I think Porsche wants to help you keep your car from being stolen.

I have never heard of a key being affected by another device but I am sure it is possible of the RF or magnetic field is strong enough.

Unfortunately sometimes keys go bad or need to be re-programmed for unknown reasons.

Thanks, Loren. I was afraid of that.
