A dealer needed an extra key for a car that was being collected that afternoon. He couldn’t wait the week for a dealer key, and didn’t want to pay dealer prices either. This era Skoda uses the same keys and transponders as VW, Seat and some Porsche.
There are 4 main ways to provide replacement car keys. Cloning the existing chip. EEPROM programming a new chip into the ECU/IMMO. OBD programming into the ECU/IMMO. Dealer only keys.
