Is it possible to add Key for Passat year 2005 with xhorse via OBD?
Some can, some you need to read ECU on bench for data. Better to clone chip and learn remote by OBD as suggested by more people, don’t risque braking the firewall plastic covers to get to the ECU (old and brittle sometimes).
Way 1:
Clone it with VVDI and remote by OBD. Easy money
