Key conundrum

Hi all New ownser of 996 C4S, will post detils in due course Car only supplied with 1 Key & Fob but managed to trck down previous owner who had other key allbeit broken case He kindly sent it & I moved electronics to new head unit. All looked good. So this 'new' key opens the doors manually, remotely opens & locks doors & turns off alarm but car will not crank. It seems that the key is not communicating with the immobiliser but is the original key. Portsmouth want £110 for a new blade from Germany, the blade works in the door & ignition so doubt that's the problem, they also want £100 + vat for 30 minutes labour to reconfigure the fob to the car with the new blase. I think the're having a bubble. This 'new' key was inactive for many moons but I have tried the reset (key in door, press button, reverse polarity ) but nothing works. In summary 1 key works perfectly, the ne one, supplied at the dame time doesn't communicate with the immobiliser anymore perhaps due to lack of activity (battery is fine) Anyone out there have any idea's ? Matt

You did dig out the transponder chip from the old case and put it in the new case :?: It isn`t just the circuit board key blade that need to be transferred over, you need the transponder chip too :thumb:

Erm What does it look like ? If it's tic tac shaped I didnt but my new head doesnt have the slot for it. Theres a tiny spring on the other side holding a tiny piece there ?

Yes it's the tic tax thing! Not sure about the slot not being in new plastic.

Yes, it`s the little tic tac thing, it sits on the opposite side of the key blade to the little spring clip that holds the blade in place. The car won`t allow the engine to start without it being in the key housing :grin:

ill give it a go. OEM head has a slot for it but seems to fit under the battery

Kurlykris you are a star. Got it out and placed it in the fob, success, even my neighbours were impressed. Thank you so much, Porsche UK said new key, Portsmouth Porsche £210+ and no other forum could help. Even the OPC 'technicians' didn't consider this. You deserve a few drinks on me so will pm you shortly for details Matt
