PIWIS II How do I program key, immo, and DME?

TL, DR: Have a 986 with no key. I have the cars iPas data. Looking for help on how to use PIWIS II to reprogram key/lock cylinder with immobilizer and DME.

Before we get started I am aware of the ECU Dr's service and I know I can order a key from porsche. Because it will be a dedicated track car, I am trying to avoid purchasing a key, if possible. Also looking at an immobilizer emulator.

I am working on a 1997 Boxster bought from an auction. The boxster did not come with the key. However, I do have a key and lock cylinder that were "paired" together from a separate 986. I am not sure if that can be used/paired with the immo or not.

On to the PIWIS... I purchased and setup a PIWIS II with the hardware. With the software, I can "talk" to the car, read/clear trouble codes, activate circuits like the fuel pump or secondary air injections system, etc. I have read over the PIWIS II user manual and several forum posts on PIWIS II, but I cannot find any information on the process of pairing the ignition lock/immobilizer/DME with the PIWIS II.

I have found a few posts where people have offered to help by private message. So that has lead me to make a post seeking information. I am new to Porsche and its diagnostic tools, but I have been doing similar things with BMW INPA/ITSA and rom flashing tools.

You need the code that came with the key. Had mine at the dealer as my key stopped lock/unlock remotely. Had to buy a new key to get the code for it.

Not sure that you can do what you want, the way you want to, but here's what I can offer:

Look here at the 'Group 8' .pdf (or find another source for the Factory workshop manual). Towards the end at section 96-30 (***Edit: I just noticed that the PDF version is indexed differently from my hard copy see 96-23 and 96-24***) it has instructions and description of programming with a PST-2.

Group 2, section 24-26 has instructions for programming the DME module (loading a different map).

I typically just replace the whole set (transponder from the fob, DME, and central locking module) with another compatible set.
I am not an attorney, mechanic, or member of the clergy. Following any advice given in my posts is done at your own peril.

Pst2 and piwis are totally different systems and the directions in the fsm do not flow to piwis.

I wrote up an article about flashing 996 maps using piwis 2. Start there.

The comment about key codes are correct. Each fob comes with a code straight from the factory that isn't recorded anywhere except on the tag that the fob comes with. Without that code, it's a paperweight.
