I am thinking about buying a 99 9-5 where the ignition was tampered with and the current owner is unable to start it. From what I have seen here it's basically a mechanical tumbler that accepts the key and it turns the electric switch below it. It possibly has a ring that might read the key ? The owner has two keys . How hard is it to replace the electrical portion of the switch ? Can I just replace all three components from a parts car and fire it up ? I searched but didn't see any results on the electrical switch replacement. Is the key cylinder individually keyed or can I get a used one and swap it out or have a locksmith key it to match existing keys ? I have a 08 so I'm familiar with the 9-5 but not too well versed on the ignition portion.
