Being a Porsche owner, you must be methodical in your approach to solving this problem.
1) Before you lost your key(s), did you have just one key that would lock and unlock both the doors, the rear trunk, the frunk, and turn the ignition on/off? If so, then all your car's lock systems are the originals from 1972 and matching. As someone already has already suggested, then you can simply take out the passenger door lock and have a local locksmith make a new key for you, or send it The Cabinetmaker on this site and have him make you a new set of keys. The reason for using the passenger door lock for making a new key is that the passenger door lock is the most likely lock to have tumblers with the least amount of wear on them. Alternatively, and as Dr.914 suggested, you can go to your local Porsche stealership and ask if they can order you a new set of keys based on your car's VIN and pay the Porsche tax for the privilege of doing so.
2) If you didn't have one key that would unlock/lock both doors, both trunks, and work the ignition, then your car has had its locks changed at sometime in its lifetime and they no longer match. In light of that, you will have to re-key all the locks and the ignition switch so the car be returned to its normal/original state of having one key work in all the lock systems. Again, The Cabinetmaker can help you do that, but you are going to have to remove all the locks and the ignition switch to have it done.
Thanks for the plug! I'll add only this. The least used lock on the car is the glove box. It's also the hardest to remove! Front trunk cylinder is the 2nd least used is also the easiest to pull. Just pull the handle out, and remove the tiny screw from the bottom of the handle. Insert something in the key slot to retain the wafers and the cylinder will slide out.
