What exactly do I need?

[single94supra]

Heres my delima. I am using a wrecked 97 boxster chassis for my murcielago project. I need to see which is going to make the most sense for me.

First, I have a key, but its the spare key(the one with the little head thing on it, with NO program in it)

The car only has 17,324 miles on it. Now, I can bite the bullet and carry the key to the dealership, have them put the programable head on it and put the program in it HOPING that it will now start. BUT, since the car has been stored for quite a few years I am affraid the box under the drivers seat(DME??) may be bad also. Can these be purchased used? I think I read it can be used IF its not been used in over 3 vehicles AND if you have the original VIN from the car it came out of AND that it be of the same year(anyone confirm).

ASSUMING I get it running, I have a few suspension peices that will have to be replaced before the real work starts(gotta cut the boxster in half behind the drivers seat, stretch it, then install the murcie body on top of it)

Okay, now lets assume for a moment that getting the used key I have, getting a programable head on it and having it programed. What is the cost?

Lets now assume that the key(which has to be done anyway to get to this step) doesnt fix it and I need a new/used box, what is the cost of this? Can I use the key I will have just had done for the car programed for use with the new box?

At this point, I dont want/need a spare key so I would prefer to use my precut key for this. IF it all works out to where she is up and running, I will have another key done as a spare.

Thanks in advance everyone!

BTW, IF all this doesnt work or is just too expensive hoping it will fix it, I am just going to cut the car in half right after the roll bars(right behind the seat) and sell the engine/trans/suspension, etc... and build a tubular rear section to hold a v8/audi trans. This will give me the stretch I need, plus make it a lot lighter in the rear to try to get the balance a little more 50/50.

Thats my story :P

Keys are programmed to the car - they can not be programmed by themselves. So the car and all keys must be together for programming.

The box under the drivers seat is the alarm/door lock/drive block control.

Most dealers charge 1 hour labor to program a key (on a working system).

So taking the car to them is a must. If I carry them the car, and the box turns out to be bad, do I have to have it reprogramed again(the key) for the new box?

Basically yes.

You must have a working alarm/door lock/drive block control to start the car - unless you decide to bypass that whole system.

Is that an option and still keep the porsche engine/ engine ecu?

Please excuse all my questions, this car has got to have the most PITA alarm/starting stuff EVER!

Ive searched on a way to bypass the whole system(box under the floor) but cant find any info on this. Care to elaborte some?

Still wondering about this?

I do not see anything on the DME 5.2.2 schematic that would keep it from running without the alarm box.

[single94supra]

Has anyone ever done it? Your saying, simply unplugging it should bypass it or do you mean, basicly jumping the box?

[Loren]

I am saying you need to bypass the alarm box altogether and run the key (via relays) to run the starter and deliver power to the engine DME.

If you don't feel comfortable doing this then find someone local that has built a kit car. This likely will be just one of that many workarounds you will need to do (IMHO).

I gotcha now, I was thinking the alarm box played a more indepth roll in the starting of the car. I thought it comunicated with the dme(ecu??) giving a known voltage(or what have you) not a standard 12v via a relay/switch.

I feel I can do this now, thought there was more to it than it appears there is. Might go out tonight and play around with it a bit. Thanks a ton Loren and hope I didnt get under your skin. Kinda hard to communicate fully what is being said by words on a screen. Nothing like talking face to face, but how often are you able to find the right person to talk to that just happens to be in front of you.

Thanks again!
