  1. Just to be clear, there is no relationship (electrical or otherwise) between the immobilizer chip in your key head and the remote control locking device in your key head. In fact, valet keys have the immobilizer (necessary to start the car) but not the remote locking xmitter (for doors and security system). So, when your dealer stated that the immobilzer "might need to be reinitialized", he meant that the car might need to be hooked up to the PST2 device and digitally mated once again to the immobilizer chip in your key head .... as is done with a new key head. Locking and unlocking the car with the remote would have no connection to that. Kim, thank you for the explaination. This is all new to me. The dealer did say that locking and unlocking the door will allow the car to recognize the key so that I can start the car. I may have misinterpreted what he was telling me. Nevertheless, this didn't help and the replacement of the anti-theft device in the car has repaired the problem (so far!!). Cary
  2. I recently purchased a 2001 carrera C2 with only 9000 miles. After about 2 weeks I started having intermittent problems with not being able to start the engine. Because it would start fine after a second or third try, I thought that I didn't step on the clutch far enough. However, last week it would not start after multiple tries. Based on discussions here, I thought the clutch microswitch went bad. I tested the switch and found it OK. I then replaced the ignition switch, still no response. I called a Porsche dealer who thought that the immobilizer need to be re-initialized (because I took the batter ground off to replace the ignition switch). However, after hitting the door lock key on the fob multiple times, it still did not work. I tried to see if an electrical attachement in the engine was loose, but everything looked great. I kept trying for several days to get the car to start, but to no avail. Finally, it did start again and I drove it to the Porsche dealer. They spent many hours trying to find the problem, and finally claimed that the problem was that the immobizer was only intermittently recognizer the clutch microswitch as closed. Therefore, they are now replacing the immobilizer at a cost of $350 and another $400 in labor (plus taxes). This car is nearly as expensive to maintain as an airplane!! Cary Mariash
