How to add Seat ibiza 2019 MQB49 5C key with Keydiy KD-X4 programmer?
OEM used key (original from another car).
Everything works perfectly, remote works on both.
But on used OEM can’t change ID, so You can’t go to dealer with this key.
This key is not a copy like BMW.
You have to solder to write data to the “new” key.
And then perform key learning in car.
(Or can generate dealer key wireless on KD ZB key and learn).
