Purchased a 2000 Boxster S a few months ago and have been addressing some of its issues with the help of this forum. After replacing the fuse in the immobilizer I was able to lock the doors using the key. Until that, the passenger door could not be locked. Although the key transmitter would light, I was unable to sync it to the immobilizer. I sent the key's circuit board to particlewave to see if it was at fault. He replaced the two buttons and soldered some broken connections. I tried all the syncing methods I've read about. Key in ignition on, off, press button within 6 seconds. Key in door, unlock, press button. Reverse battery, press button, wait 10 seconds, reverse back. Nothing worked. Any suggestions as to what my next step should be?
Thanks,
Ric
