I have a tough question for any advanced Renntech users who have either stripped a 997 back to minimum wiring for racing, or fixed key issues
Can anyone help with my alarm issues.
Im building a 997 Track car- using a salvage chassis and the remaining parts from a rolled and written off cabriolet. Im think the key worked to unlock to car before i pulled it apart, but cant be certain as the engine was already out so there were limit functions to activate then.
Since moving the dashboard and whole wiring loom into race chassis, I can unlock the doors (yes, its the correct key, ive moved the doors over too), and the dashboard lights up to tell me the current odometer values. However the whole time from when the battery is connected, the alarm siren is going off (currently a clamp muffles that noise to save the neighbors). I can put the key in the barrel, rotate, and then still remove it (the Barrel lock appears to electrically be live, as it releases the key).
My guess if that the key has lost its coding for the alarm system, but I've tried following these instructions, https://rennlist.com/forums/997-foru...working-2.html,
with all combinations of button holding, pushing the hazard light switch, foot on brake, and key in/out barrel .... without any success in recoding the key.
Its worth noting the windows dont go through the usual drop down upon lifting the door latch sequence, im assuming this is due to the alarm running.
- my options seem to be getting the local agent to reprogram the key
- are there any other steps i should try to revive the key. I do only have 1 for the wrecked chassis's system
- a final last though is am i missing some switch that needs bridging from the cabriolet circuits to tell if the roof is down/up
I purchased a 1999 Porsche Boxster 986 about a year ago and I'm having a few problems with the electrical accessories. The top worked fine when I bought it, but now it won't work sometimes. The radio also turns on, then immediately off at startup, and it won' turn back on until a few minutes later either by itself, when I use turn signals, power windows, brake, or even just by itself. After the car is "warmed up", then it will stay on. Other things won't work right or not at all, such as the alarms for, ignition, door open, light switches, etc. The fuses are all fine, and I know the battery had been replaced right before I purchased it. I haven't checked the relay for the top, but I am about to do that now. I feel like there could be a single problem creating all these issues. Any help would be greatly helpful and appreciated!

On my '08 GTS I have a few things happening. First, when arming the alarm, the hazards flash four times instead o the customary two. Is this an indication of a malfunction?
Second, the rear hatch will not fully close when pressing the button on the liftgate. It will close when pressure is applied to the gate when closing.
Both of these happened after the dealer replaced the driver's door module and re-coded the car.
Any ideas on where to begin? Other than going back to the dealer.

I'm having electrical issues with my 2000 Boxster S.
My windows drop when the doors are opened, but they do not respond to the window controls. They do not come down when the Convertible top handle is pulled.
The doors do not lock or unlock with the console button or the remote. I can only lock the driver door.
The defrost button does not respond.
I replaced the C3 and D1 fuses even though they looked and tested good.
I'm getting 13 volts (when the car is on) at the C3 and D1 positions.
I pulled the console and tested voltage to the switches and couldn't find any voltage between any two of the many wires going to each switch.
I replaced the module under the driver seat with a new one from Suncoast Porsche and had my local dealer reprogram the new one from the old one's data. The only difference is that my convertible top started working soon after that.
I read in other postings about SPDT relays that are just above the fuses, but I can't find any information about which relay would be affecting these components.
Any ideas on next steps?
I just purchased a 2015 Cayenne Diesel. When I lock the car, it used to lock down AND made a chirping sound. After replacing a couple of fuses ("shuffling" as a matter of figuring out which fuse to replace), it stopped chirping. The door lock light comes on steady for several seconds then starts blinking. Thought it may be the "horn setting" but I can't find it in the manual. I suspect that one of the fuses I unplugged may have reset this setting? Does anyone know how to restore the original "lock and chirp" setting.
