This project came to me from Blue S2 (Tony) of RennList
and I thought it was a nicely documented fix for an
irritating little problem. Most of our Porsches came with
keys that have small lights in them. These eventually fail
and Tony came up with a fix for this problem. He asks for no
payment of any sort and agreed to allow my
presentation of his post here. Thanks Tony.
Hey
everyone, i cant remember who posted this originally but i
was trying to follow the directions for the LED keylight and
i found them overly complex. Paper, tape, wire,
solder...this is a key, not a bomb. Anyways, i found a much
simpler way to do this and i have part numbers and pictures
for ya too! Ok, this is what you need-
- 5mm
White (or any other color) LED 3.6 volt, 20ma 1100mcd
RadioShack # 276-320
- 2 -
Energizer watch batteries # 389
- Approx.
$10 (total cost for 2 batteries and LED)
- First
open your key and remove the battery, copper divider,
foam cushion, and old light.
- Second,
insert the LED light into the hole. The short post goes
to the battery, and the long post gets wrapped securely
around the copper pole. Keep the original spring!
- Third,
place the two batteries on the spring. Positive side up.
The short LED pole should be placed ONTOP of the
batteries. I had it to the side in the picture because
it wouldnt stay without the cap on. When you assemble
it, the pole has to be ONTOP of the batteries.
-
- If its
to the side, it wont work consistently.
- Next,
balance the cap on top of the batteries and pole. The
pole should be sandwiched between the cap and batteries.
Just get it to stay, it wont be secured until you close
the whole key. Its a little tricky, as the batteries
teeter a bit on the spring. Just try to keep it all
together. Once its closed up, it will stay. (just make
sure that pole IS ontop of the batteries when you close
it up.
-
- Carefully
close up the key. You should have a very nice button
feel. Firm, yet good movement. I think it feels much
better than the original. Now i have to wait til monday
to do my other key because radio shack was out of white
LEDs.
If you have
any questions feel free to contact me, or post on the board.
Again, i dont remember who originally posted this, but
thanks for the idea! Just felt this was an easier way to go.
I hope this helps. I just couldnt follow the original post.
Plus, no part numbers were listed. It almost seemed like the
workshop manuals! HAHA! (j/k..) Now i got my LED keys, my
Hella H4s...im ready to light up the night!

Follow-on info... If you need to buy the original key,
there are 2 parts - a key blank (the part that gets cut to
fit your ignition) and a key head (the part with the light).
The two parts can be easily joined. The local hardware store
cut the new key blank without a problem. Part numbers are as
follows:
Key Blank - 944 538 331 00
Key Head - 944 538 041 00
