Hi all,

I searched for half an hour to find definte answers for my qustions:

- What is the procedure to programm a key head to the Immobilizer?

- Can used key heads be programmed or learned into the cars computer and what device is used to do so (without having the bar code thats supplied with brand new ones)?

Any help or pointers are highly appreciated.
The technicians in Down Under don't seem to know what the deal is (I am getting all sorts of weird answers....)

Thanks and best regards

Martin

You must have the bar code and the dealer needs to perform this task.

Best.

Hi Marc,

so there is no way a key bought on Ebay can be programmed to work in any way?

It can only be programmed by the dealer. I just bought one from ebay and had to have the dealer program it. $125 US.

Hi Frank,

that is interesting.
Tell me more: did you have the card with the barcode on it or was it a used key that the dealer learned into the cars computer?

If that is the case, please give me your dealers contact information so I can get in touch with them....

Thanks and best regards

The key can be programmed to run the car without the bar code, however the remote functions can only be coded to the car if the key comes with the original bar code number. In addition to the key and the bar code number you need a PIWIS or PST2 and the learning code for your car.

Martin,
What Todd said. The PIWIS or PST2 are dealer computer code reader/programming tools. I think an independent can rent one of these for $5k+US with more $$ needed for software upgrades. The dealer can get your car code by entering the serial number into the Porsche data base. I do not think the dealer can program a remote without the bar code for that head. The two heads that are pictured in your original post have the needed codes attached.

Below is an excerpt from a post on Renntech;
"Durametric, while an absolutely awesome tool (I have one and recommend it to most DIYers), only reads codes and can give actual values, and let you clear check engine lights and some other things. It is a very good diagnostic tool. It will not let you program the DME, however. The enthusiast version cost less that 300 USD.

PIWIS is the latest version of the Porsche tester, which I understand is only available by lease to Porsche shops and independents and runs 5 figures, plus yearly updates. A PIWIS does everything, including allowing you to make changes to the DME. The PST2 is the PIWIS predecessor, but will not work with 9x7s."

Hi all,

thanks for the info.
In summary:
There is a way to get the key working to start the car, but not the remote function?

Only the remote function needs the barcode?

Do I understand this correctly.

Best regards

If the new key's blade is cut to fit the ignition lock the key module can be separated and the RFID pill removed and replaced with one from a key that starts the engine.

However, the new key's button functions will not have any effect on the car's subsystems cause the key button electronic RF signatures are not recognized by the car's security system.

There are a limited number of slots for keys in the car's security system. If one wants to replace an old key with a new one my info is the old key is needed to remove it from the security system to free up a slot for the new replacement key.

Sincerely,

Macster.

As I stated above, if you have the cars learning code, the key, more specifically, the RFID pill can be matched to the immobilzer to run the car. Without the bar code tag the remote functions cannot be programmed to be recognized by the immobilzer.

The only way anyone, dealer included, can program that key is if they have the 24 digit key code located on the paper fob attached to the key head...then you'll need the PST2 or PIWIS to program..that's it there isn't another way I can think of..sorry

I just had my 986S reprogrammed for two keys. One, I had the barcode for, the other I didn't. Tech said the car has enough slots to program 5 keys.

Barcode key: remote works, key opens door, key starts car.
Non-barcode key: remote does not work, key opens door, key starts car. You should be able to do this with an ebay key.

Be prepared to be gouged, though: stealership charged $180 for the programming New key (w/barcode) will run ~$120 from Sunset.

Sounds like they disabled your immobilizer. Not sure how they would be able to pair an unknown key to it.
