2005 Saab 9-3 failed to add key ( I had correct pin code and working key ) Also tried to write key by dump with Autel IM608 ... to do with CIM with EEPROM clip did not work failed.
Then, I used the VVDI prog and VVDI 2 success. Was able to program the Pod key and also used an XT27a super chip for testing to emulate an already programmed key slot success as well ...VVDI prog with EEPROM clip adaptor can read-write in-circuit no need to remove EEPROM. Just make sure to a short quartz crystal
Question:
Why short quartz crystal, to not wake processor? short with some tweezers or solder wire, or need to hook up with those two wires on vvdi prog clip, beside an EEPROM clip?
Answer:
Without crystal shorted get bad read and write... . I short with alligator clip
