Keys/fob stolen. Need replacement sources asap.

Bruce, not sure I understand you...

Yes, the car has an alarm/immobilizer ECU independent of the Motronic ECU if I understand correct. It is behind the drivers seat on my GTS, behind the removable panel. When purchasing a new one, it's my understanding it comes with a new PIN and a set of 3 fobs.

My understanding is that it cannot be eliminated.

First, if you can get a key for $325 bucks. Do it. That's seriously cheap and eliminates 1/2 of the problem. If you can get a used alarm system from a member here and it works.. go for it.

The FOBS are the same as the 360 and some Porsche 993 cars. Therefore I highly suspect that the basic system is the same on the models. In fact on the 993, you have to press the FOB to start it.. just like the 360.

There are two components, the Alarm ECU that makes the horn honk, locks the doors on the press of the button, etc. and the Immobilizer. What the immobilizer does is either disable the ignition or prevent the starter from turning.

On the 993, you can buy a replacement relay that bypasses the immobilizer and I think a special ECU. Voila! No more need to press the FOB prior to starting.

On the 360, IIRC on electrical connection 15 or 6 there is an output to the alarm system and the engine ECU. When you press the FOB, the immobilizer sends a signal to the engine ecu that enables the Ignition on the engine. On other cars that use this method, there are Bypasses that replicate the "Go" signal, that mean you can start the car with the twist of the key. I'd have to replicate the output.. and I don't want that on a public forum. OTOH the bad guys already know this and will flatbed any car they really want. True security is a GPS tracker IMHO.

 

My dealer quoted me about $1500 all in for new PIN, new FOBS, but I didn't need a key.

You wont have any luck swapping your immobilizer from another car, it is coded to the ECU. Even if you swapped the immobilizer and ECU you would still wind up at the dealer to make it work.

The Comprehensive coverage on your DD should cover the cost of this since it was stolen out of your car.

 

Unfortunately turning the battery power off regardless of your method will NOT disable the immobilizer. This is one of the reasons I have bypassed my immobilizer on the drivers side door.
If the passenger side door is open and I don't want the immobilizer to kick in then I have to cycle the key after the passenger door is closed. As I type this it makes me think, there may be some number of key cycles you need to do that will disable the immobilizer, hopefully someone has figured that out. I hope it works out for you.

 

Ketel is not asking about the immobilizer in Q1, he is asking how to kill the alarm once he uses the key (not fob) to get inside the car...

My guess is he does not want the siren blasting for who knows how long....

 

Oh, got it okay, my mistake. I had the siren go off once when a friend of mine was fiddling with the remote and hit the panic button by mistake. We didn't realize that was the cause and we tried to get it to stop by turning the battery cut off but it would just blare again when reconnecting the battery. We also tried putting the key in the ignition and turning it to the start area but that also did not stop the blaring. After almost going insane, since that has never happened to me my friend fumbled with the fob and managed to press the panic button again this time disabling the alarm. All that to say the only way I was able to get the thing to stop blaring was by using the fob.

 

I think that will help him. Short term, he just needs to get the car open and with the battery off (and the alarm not blasting), he can swap the alarm out.

 

Ketel, I sold an Immobilizer and alarm ECU with a black FOB and PIN number to Russ at Ferrparts. Call him. He may still have it. The Immobilizer and alarm ECU is a quick swap. Can be done in 30 minutes with some simple tools. Need to turn off the battery first.

I'm pretty sure the alarm will go off when you kill the battery. The siren is located opposite the battery housing on the drivers side.

 

John, having the PIN is fantastic. You can program the new FOB's to the PIN. Terry TAZ made a how to document, I have it but I'm posting from iPad now.

 

John, here you go. Also, if you call Mike at Algar, he can have Tony (one of the best tech's) walk you thru it:

The alarm will keep blaring even if you disconnect the car battery. The alarm horn has a battery on board that runs the system regardless of the car battery

If you have a key, and the PIN, you should be able to start the car.

Workshop Manual Volume 3, Page H-18 lays out the procedure to start and run the car with the Pin and without the Fob....

 

I just armed my car (rarely do that).

I unlocked the the drivers door with the key and opened the door. The lights flash, but I do not have the siren blaring. It stayed that way for over 2 minutes until i just reset it.

Suspect you could open the door and do the key code trick as I mentioned above to disable the alarm / immobilizer and start the car.

Best of luck and let is know what happens.

 

I have 2 black fobs and 1 red fob + PIN if you are interested. Make an offer.
