Hi.
Sorry, but I've been unable to find a clear answer regarding this situation...I desire to duplicate the flipkey to my 2004 Jetta, not replace it. I've read that the transponders in my functional original keys are non-rewritable--so in programming 2 additional, new flipkeys as duplicate spares, how do I preserve the functionality of my original keys (simply, by what method may I program the new "spare" keys without obsoleting my old keys.) Maybe I'm misunderstanding--but the process of adapting blank keys to the system clears the system's association with the non-rewritable original key--rendering the original key unable to start the car (but still capable of remote unlock and manual unlock,) correct? So can spares be made through VAG-COM or VAG-TACHO? I have both, along with proper cables. The 2 new flipkeys have been cut properly.
Thank you for your help, and again, sorry if I overlooked a pre-existing answer.
Kind Regards,

It's been a while since I had to program my key, but I think you can have up to 4 keys programmed. VAG tacho lets you add keys up to the max of 4 without deleting old ones iirc.

Unless you change the cluster the old keys will still work regardless if you add more keys for the immobilzer part.

On the other hand, it is possible to reset the programming for the remote access and have the control module forget the previous keys, but it's also easy to add them back with VCDS should you find them all and do it as a group.
