My local dealership gave me a code that wasn't the code on the card which allowed me to program my spare key.
Not sure if the same system is in place in Europe as the US but maybe call another dealership?
You obviously need proof of ownership but otherwise it was easy to get them to give me the code.

Also, does any member know if an OEM Porsche fob from outside the United States can be programmed in the United States and operate a U.S. Porsche?

Finally with a bit of "persuasion" I got those 4 digits! But I think the guy at the dealership is convinced I'll come back as he's persuaded that I'll to connect the car with their server ![hiha](https://rennlist.com/forums/graemlins/roflmao.gif)
I'll prrogram my key fobs tomorrow.
Thanks for your help and have a great week-end!

I have two (2) key fobs, both of which are original to my car. Both work perfectly as designed, identified as fobs #1 and #2. I am purchasing two (2) additional new fobs, identified as fobs #3 and #4. Can I simply program the additional new fobs #3 and #4 the same as #1 and #2 and have all of the fobs function the same?

Thank you. I will be adding two (2) new fobs in addition to the original fobs. Can I program the additional fobs to my cars code and have all four work identically or is there an additional step to be taken for the four to work identically?

Thank you. I reread the key fob set up procedure 11-2.pdf and it appears even if I have two (2) operating fobs then I must follow the final step for each fob, including the additional fobs, in order for the entire group to work identically.

Others here may be able to provide validation that it works on their pre-1996 USA or ROW vehicle.

That's correct. The entire batch has to be programmed even though you have 2 working ones.

New to the group, apologize if this has been asked and answered. Been trying to add 2 additional Fobs for a while. Followed the procedure, but can never get the immobilizer light to get to program mode (blinking). I have 1Fob that is working and it seems that all the prerequisites are good as well. Any thoughts before I head to Porsche to have them do it?

There are a set of contacts that close when the key is inserted in the ignition. They're wired to the immobilizer and are important for programming. If they're bad (like mine are) you won't be able to program the FOBS. Nothing wrong with the immobilizer or the FOBS, the immo just isn't getting a signal it needs to enter program mode. ECU Docs did mine for me, likely using a fixture to simulate the needed signals.
The schematics suggest that the "gong" should sound when the door is open with the key in the ignition (mine doesn't). If yours doesn't sound you probably have the same problem.

If the immobilizer light functions, e.g. turns off after 10-15 seconds when the key is initially cycled, then the buzzer input (12V to pin 7) to the immobilizer is OK.

Also curious about the code matching the last 4 of the immo serial.

I'd also like to know, as I didn't receive any code with my 993 from the previous owner. Also, is the code used to program the remotes the same code that is used to "emergency start" the vehicle if your remote is dead and you use the key to enter the vehicle? That process is described in the owner's manual but I'm not sure if it would be the same code.
Also curious about the code matching the last 4 of the immo serial.
