2002 Audi A4 key programming

[Jimmy07]

Hello All

Back to my nemesis 😬

Managed to lishi pick lock, decode and cut key, worked perfect then got Keydiy and generated key fob.

So far so good hooked up Supervag and programmed remote all good.

Here’s where it went funky.

Supervag wouldn’t do key learning on this car or read pin. Plugged in MVP it wouldn’t pull pin. Used vag reader got 4 digit pin ok. Back in with Supervag in menu went to key programming it asked how many keys to programme put in 2. Got them programmed but here it is !

One key immo light staying on solid other key immo light flashing. Car is starting and fobs working also.

This is twice this has happened now. Done everything to the letter and this again. MVP wouldn’t extinguish lights either.

Is there a fix for this?

Will battery disconnect sort this, if so do both the original and new key stay programmed or does it revert back to one key settings prior to me trying to programme spare ?

Is there a lockout after pin reading, if so why was I able to programme 2 keys ?

Ready to burn the van with everything in it 🤬

Any help would be greatly appreciated
