roland3337,
The reason why your Porsche Boxster may not even crank could be a blown fuse which interacts with the Immobilizer.
Check these in your fuse box, and also check the fuse in fron of the Immobilizer itself also. Please call us to help you.
Paul,
Almost 90% of the time we can recover the Coding Data in the Immobilizer to save and reuse the original remote keys when we do an Immobilizer Replacement.
