OK maybe this is the place to find an answer...
I recently bought a 99 boxster... it had a dead battery when I bought it so I replaced it. (of coarse now I need to call the dealer to get the radio code)
So I began to notice that every so often I get in and turn the key... all lights and everything works but the car does not crank or start... I clutch if a few times, take key out and try again... then all of the sudden it will work fine.... this can happen if the car has sat... or if I shut it off and try it right away...
They key is one of those laser cut keys
