This is the Porsche parts catalogue for all cars since the 356. The 97 alarm part # 351 shows as good for the 97MY only.

... or Central Locking Unit under the driver's seat cannot be reprogrammed into another car.
The memory allow for only one programming, so you may need a new one.
I have had success drying CLUs.
Take it out of the car and remove the printed circuit board.
Dunk the board in Isopropyl Alcohol for 30 minutes.
Shake dry and wait for it toi completely dry before reassembling and reconnecting.
Make sure that the carpets are also dry before reinstalling.
Happy Boxstering,
Pedro

If need be, try ECU Doctors. I believe they can repairs. Google search will locate their website.
