Anyone reprogram the central locking system?
So at least on my '84 both doors have to be closed in order to lock the doors with the CLS button. This is not convenient when you are getting out of the car with a passenger since you have to wait until they get out and close the door before locking it, either with the CLS or manually. And since the lock is far back on the door I just find it easier to get out of the car and walk around to the passenger side to lock it.
Ideally it would be great to be able to hit the CLS button to lock both doors even if they are open. Or if when you locked the driver side with the key it would also automatically lock the passenger side. Has anyone ever tried to reprogram the CLS to do this or at least be more convenient to use while exiting the car?

It is a mechanical feature of the driver's side door locking mechanism (inner). A lever/linkage prevents the lock from being activated if the door jamb strike post has not engaged.
This is to prevent you from locking your keys in the car. No "reprogramming" can change a mechanical link, unless you dissect the inner lock mechanism and manage to remove that linkage/pin.
The passenger side door can be locked while open, but driver's side can not.
Cheers!

Hmm...my car will only lock the door that the key is locking not both. The owner's manual does not mention that both should lock at once, but Walt since you also have an '84 I am going to assume I have something amiss with my system.
I wish mine would work this way so I could at least lock the passenger door when the passenger is getting out instead of waiting for them to close the door. The MY 84 was not designed to work the way you said, it appears, at least according to the owner's manual....

Porsche engineers were creative
EDIT: I think your lock motors will still begin to operate when you push the central lock button, but will then continue to unlock again if one or both doors are open. So you should hear them run in your situation.
EDIT 2: Just noticed your issue that the key only locks the door it is in....yes that indicates something wrong with your system...possibly the electrical connection on the door lock itself.

If your central lock button locks and unlocks both of your doors I would recommend getting a fob which would allow keyless entry. I just installed mine earlier this year and I haven't used a key to open or lock my doors since. Best $20 I ever spent on my car.

Your car just isn't working right - as other have noted central locking means both locks follow each other, unlock driver's side & passenger's side should also unlock, unlock passenger's side & driver's side should also unlock. Locking - if both doors are closed - is the same - key in either side should lock both. If passenger door is open you can pre-lock it while locking the drivers side - it will be locked when subsequently closed. You cannot pre-lock the drivers door (e.g. lock when it is not closed) - ergo if you try to lock either side with the driver door open they will revert to unlock again (so you can't easily lock yourself out).
Your car should do pretty much what you want - it's just not working right...
Central lock button on dash should also lock both doors or unlock both doors (alternately) as long as the ignition is on, with ignition off it should only lock both doors (as a security feature).

Thanks Alan. Yeah my CLS works as intended when pressing the red key button on the center console except that it only works with the ignition on. Key out it doesn't do anything. I'm guessing this is also related to it not locking the opposite door when using the key. I'll be breaking into the WDs to understand the system. Any suggestions on how best to troubleshoot?

If you go to the link below at post #54 you can see a detailed description of what I did. This write up is for a 1990, but I believe that the same module would work but would just require different wiring connections for your model year. That being said, I didn't realize that your central locking button didn't work with the ignition off. If that is the case I imagine that you would have to at least get that working before hooking up a keyless entry system.

Plenty of previous articles on it. A non-functional central lock button shouldn't matter as long as the door locks work correctly ...Here they don't yet - so that is what most needs to be fixed.
I do agree a KE is a really handy convenience feature. Certainly on a GTS it should have been standard by 1993 - it was on many non-luxury cars by then.

You are right of course--when I hooked everything up I never connected anything directly to the central lock button, so that comment was a bit misleading. I was just looking at that as a sign of one's locks working as they should. Installing a KE system can bypass certain issues, but it's almost always the best course of action to get everything working perfectly before installing a KE system.
In my car my central locking button locked and unlocked the doors as intended, but when using a key on the driver side door it wouldn't lock/unlock the passenger side door. The key on the passenger side door would lock and unlock both the driver and passenger door though. Installing keyless entry made that problem a non-issue as the fob now locks and unlocks everything as it should. They key just gets used for the ignition now. Funnily enough I have since figured out what was causing the key problem in the driver door but I'll probably never use it again anyways.
