Hello, I recently purchased a 1982 928 from an estate settlement auction in "not running, no keys" condition. Last week I brought all the paperwork to a Porsche dealer with the VIN and the parts department ordered a key for me from the VIN records. Yesterday the key arrived and I picked it up and eagerly headed home to try it. The key fits into the ignition lock, door lock, hatch lock, glove lock and gas cap lock such that it appears to be the correct width and length but does not turn at all in any cylinders. The parts rep explained that it would only work if all lock cyls were original, I understand that. It is entirely possible that all cyls have been changed at some point in the last 34 years but the dust layers on them and the surrounding area sure suggest they look like original equipment. Regardless, I am looking for advice on the next step forward in this "obtain a correct key" process. I would rather not replace all the lock cyls on the car if possible. I have read many different threads that suggest different approaches. I would be willing to gamble that a certain pattern key would fit all the locks on the car. Given that premise, is it possible to remove a certain lock cyl easier than others and read a code on the outside of the cyl and then somehow obtain a key for that code? I will try to attach a photo of the key the dealer special ordered for me that doesn't work.
Also, does this key style/type look correct for a 1982 928? Thanks, Dan
