Key problems
 

i have two keys, one works the other doesn't. Bad key unlocks the door fits in the ignition, turns all the way in both directions brings on electrics but will not crank the car, any help? Do apologize if this has been covered elsewhere, i am new here and do not know how to search the forum.

It seems the immobilizer does not recognize the key, either the key is bad or it needs to be coded. You will need a Porsche System Tester 2 or take it to a dealer to get the key coded into the system.

Thanks, will run by the dealer soon
