Hi I never got the second key for my 996. Seller said he posted it on but.... anyway I wonder what is involved? I assume a main dealer is part of the deal? If anyone who has been thorough the process can point me in the right direction and what I am going to need, can I use a used top say and re code? etc.
Thanks Dave
 
Neither fob nor blade from third-party can be reused if already cut/coded (obviously the existing blade or fob can be reused)

Best bet for an easy life is OPC.

You will need V5 and proof of ID (passport/driving licence) and they will order the blade cut from factory. Fob can be coded of the shelf by OPC.

Beware uncoded fobs on eBay etc that don't have 24-digit coding serial (barcode) and never buy a previously coded fob.

Quite a lot of money is involved ... about £250 ... so, if you can reach the seller, it might be worth pressing him to at least share the cost.
 
I've been looking into getting a spare key for mine.

You can get a key cut from a guy on ebay for £10. You will need an immobiliser chip (either a clone of the existing, or a new one added to the car) for it to start the car. It also won't have remote buttons.

You can either buy a chip and have porsche (or a friendly indy with the PIWIS or PST tester) add that chip to your car's computer for the cost of an hours labour. - if you can convince them to work with parts they have not supplied.

Or a suitably equipped auto electrician may be able to clone your existing chip. Early cars (98-99) used a different chip to later.

I'm trying to find and auto electrician locally with the required hardware (called a "Zed Bull") to read and write transponder chips, who should be able to advise me on cloning.

If you want a new key with remote functions - then I believe it is porsche / good indy only as you need a code that relates to the remote that comes with the new remote head, and that needs to be entered via PIWIS / PST. In this case you could get the key blank made up by the bloke of ebay to save a few quid.....
 
My car indeed is a 98 so I wonder as it is pre "super" electronics if it can be cloned?

I only have one key, so was thinking about this option..

These guys will clone an existing transponder (hence requiring a working key) as I have described.

£85 is still a lot, I have paid £15 for a key cut and blank transponder, I just need my transponder written which will take 30 secs using an appropriate device, or I can buy a transponder cloner from china for £100......

97-99 cars used the fixed code "ID13" megamos transponder chips which can be duplicated onto writeable "T5" blank chips.

99-? cars used ID48 encrypted chips, same as VW etc, these can also be cloned but need a a cloning machine capable of breaking the encryption.

http://www.transpondery.com/transponder_catalog/porsche_transponder_catalog.html

I understand most branches of Timpsons have the transponder cloning machines, so I will take mine next time I'm in town.

I will update with my experience....
 
Well I took my key along to timspons to get the blank chip written.

They scanned my original key and found it to be an ID48 not an ID13 as a number of locksmiths have told me.

These cannot me copied. So my car must be a late 99 car.

An ID48 transponder is encrypted so can't be copied, it needs adding into the ecu - so needs a PIWIS and access codes from Porsche.

Probably a job for the dealer. Once I've got a replacement ID48 chip I'll ring the dealer and try to convince them to do it for 1/2 hour labour.....
 
these guys do Porsche Keys, my mate used them when he lost all his keys to his 996 carrera, he dropped his only key down the storm drain when he got to work in the pouring rain (he was pissed),and he said they even had it in stock which I guess if you do car keys for a living is no surprise, but keys for a Porsche in stock and there not even the dealer, it was a surprise to me? He rang everywhere and no one was interested and then he rang these guys and he said it was no effort for them at all which if all keys were lost on a porsche i would of thought it would of been major problems? Anyway picked his car up at the end of the day after work and the drama was all over, who would of thought it could be that simple without a visit to Porsche themselves

They must have the tools (either PIWIS or PST2 or something hacked) to add keys to the ECU.

I know for VAG motors you can get a wire and software called VAGTACHO which cracks the encryption to get immobiliser PIN codes, which you can then use with VAG-COM software and wire to add keys to the ECU. I know this because I used them myself to fit new clocks to an Audi TT.

I've not found anything similar for these post 1999 Porsche to add keys without a PIWIS / PST2 and dealer supplied codes.
 
Here we go, you can now buy an ID48 clone tool:

http://www.tradelocks.co.uk/blog/id48-cloning-now-cracked-keyline-with-megamos/

"With the Megamos system, almost anyone can now clone an ID48 chip on models up to around 2003. And the cost of the ID48 cloned key will cost the user around £19.50+VAT which is a remarkable price, and we are certain almost everyone involved in cloning will want to buy it!"

The device is £219 + vat (add on to their cloning device)

looked into getting a spare key for my early 1999 registered 996, timpsons checked it and confirmed a megamoss id48 transponder which they could not clone. A specialist key guy near to me (starkeys, kingsley) has checked it and said he can clone the transponder and cut a key if he has access to the car, which would get me a working second key but just a basic key, no remote open function. This I was quoted 80quid for, I have not yet checked the opc but I believe it's over 200 for a new remote key.
 
Now I'm a poor man and a cheapskate... but whenever I read this topic I think sod that, I'll go to the OPC for my second key!
