I have a 2002 Porsche 996 Cabrio and earlier this year the immobolizer under the seat got wet. I purchased a used immobilizer, key for and ECU behind the rear seat. All of the parts came from the some year model etc. I put the parts in myself and everything worked great. Now i need a new key fob or atleast I think i do. The remote work sometimes and most of the time is doesn't. When its not working I cant lock or unlock the car with the remote and the front trunk will not open with the fob or the switch inside the car. When the fob works everthing works as it should in the car. Do you think this is a key fob issue or something else? Can i even get a key head programmed since these part are from a donor car? I do have the vin of the donor car. Please help!
2002 C4S (996).. I did a search but nothing definitive. Sounds like replacing the remote key worked for some people, and other people had luck doing otherwise or just didn't close their thread if they ever found a solution. I'm experiencing the following which was never a problem until a week ago: Sometimes the key remote opens/locks, sometimes it doesn't. It seems either that the remote device has an issue or it's somehow intermittently getting out of sync with the receiving unit in the vehicle. When I hit the button on the key I can see the light blinking on the key. When it's working I see the little red light on the vehicle dash receiver flash in "response". When it's not working I don't see the receiver flash at all. The lock/unlock button seems to only work intermittently. When the remote unlock does not work it seems that manually unlocking with the key, putting the key in the ignioion, then taking the key out and trying the lock/unlock button again makes it work again temporairly right away. The system works just fine when I use the key to unlock the doors the old fashioned way (manually using the key itself), etc.... so I'm thinking this is likely something more with the remote device in the key than it is with the central alarm and control unit within the car. If it is the remote key, what else could need to be replaced beside a battery? Can these remote devices in the Porsche keys just "go bad"? Strange that it's not just completely not working and does work intermittently still. Some other notes: - Durametric is showing no faults under "Alarm". (The only fault the entire car shows in any category is under "Seat Memory" and this hall sensor error has been observed by me in the past well before this issue surfaced, so I believe it's unrelated). - I ordered a CR 2032 battery to replace in my key but I'm assuming this isn't the issue since the little red light still blinks just fine when the button is depressed. I will see if that works when it gets here in a couple days. - The car came with a second key which I have never tried to use until this happened. This second key works just fine manually but the remote lock/unlock on it does not work at all (despite the fact that I see the red light flashing on the key). Any ideas would be greatly appreciated. Thanks in advance.
