I would start with the battery on the remote. Maybe clean the remote terminals with a nail file. The wiring looks fine.

What do you think of the blue/white vs blue/black?

Update:

I replaced the remote batteries with new ones. No change there.

I swapped the blue wire with a white tracer for the blue wire with a black tracer and connected it to the brown wire with green tracer. The green wire with the black tracer is now connected to the brown wire with the blue tracer.

When I start the car, the door locks "lock". When I turn it off, the door locks "unlock".

I just can't get the remotes to work....

It's been a while, but I remember having to program the remotes before they worked. If I remember correctly, there was a separate sheet in the about this.

ADDING / DELETING REMOTE
TRANSMITTERS
Adding new transmitters to the system will
automatically delete all other remotes that
were previously operating the system.
NOTE: You must code all desired remotes
at this time.The unit can learn a maximum of
three transmitters.

To enter Code Learning Mode:
1. Turn ignition key on, off, on, off, on and
leave on within 5 seconds.The horn will
chirp (if installed) and the LED / parking
lights will flash once.

2. Press and hold valet switch for 3
seconds.The horn will chirp and the LED
/ parking lights will flash 3 times.

3. Release the program switch.

4. Program all desired remotes by pressing
button 1 on each of the transmitters.
The parking lights will flash after the
system has learned each remote control.

5. Turn ignition key off. Remotes are now
programmed to the system

I wish I could help, call the mfg and have your facts down on what wire is connected to what and whats happening.
It could be a function of programing the controller box. On mine if I remember correctly, I had to count flashes of the LED to understand what was being programed in the box; by switching off and on of valet switch.
I set mine up to flash parking lights when being locked or unlocked and auto lock/unlock when I start/shut-off engine. No horn beeps it takes away form hearing the locks actuate.

Thanks guys. I thought the remotes were set as is. I'll look into it more.

When I ground the blue and green wires, the doors lock and unlock (and I can see/hear them). It's like there is no signal being sent/received or the control box isn't sending the signal to the locks.

Seems like we have memory issues here on the Cape! :)

Yeah, this was one of those things that took a lot of head scratching in the beginning but I haven't touched since. Hopefully, this weather will clear up soon and I'll be able to remember how to drive the car.

I fired up mine Sat. after a 3+month sleep. 2 seconds' on the key and vroom. Shot around for an hour before the heavy rain. My new toy is one of those LM1 a/f meters so I'll be checking my engine tune this Sat.

Thanks PSJoyce and rcaradimos! I programmed the remotes and it works like a charm!

Guys thanks for all the above information, I just installed the BW 855 on my 930 and does work perfect!!!

Sorry to revive an old thread, but I would like to get keyless entry with basic lock/unlock with remote. I don't need any other features. I have an 89 3.2 with the factory security system. Anyone know if the unit below would work? How would I wire it for basic lock/unlock?

That should work. Check the wiring colors/functions against the diagram above. More info here:

Yeap

No problem

The wires for the door is located on the driverside circular connector where the hinge sits.

You will take the power from the fuse panel but most important is your selection of a ground.

Below is a link to the wiring diagram of the keyless module I want to buy. I understand that Porsche uses the negative trigger? I think I understand where I connect the close signal and open signal to the Porsche wiring. Which of the remaining wires would be ground? For power would I connect the red wire to constant power on the fuse box? Any help with which wire goes where would be appreciated!

Yellow and yellow/black go to ground, red is constant power and black goes to the battery negative from your diagram. The extra details in the figures below the main diagram on top are for the top 6 wires in the main diagram. Use a fuse the protect the wiring/box.
