Door lock issue
Here's a strange one...the key fob is not unlocking the doors correctly. I know how to set the comfort settings and it is set for all doors.
Here is what happens.
Push button to lock doors - no problem
Return to vehicle and push button - all doors unlock except drivers door
Push button again - all doors lock
Push button again - all doors including drivers door unlocks.
This is the process I go through every time to get into the vehicle. Ideas????

Shoot, I can't remember but it doesn't happen anymore. It was one of two things, I either reset factory defaults then selected my options again or, it was about the time that I had to change the vehicle battery. Obviously try the default reset first! If something else comes to mind I'll let you know.

Mine has been doing the same thing for the past couple of months, except it's the front passenger door that won't unlock initially. That's a lot less annoying than the driver's side door of course!

Just to follow up, I did the factory reset on the "Comfort" options today and then reset everything the way I like it, including "unlock" allowing all four doors to be opened. Now they operate correctly; no more issues with the front passenger door.

I'm still having the problem. I'm going to try the battery but I've changed it twice in the last year! 2nd was under warranty but the parts shop is going to wonder what's up. Do Cayenne's kill batteries? Any suggestions why?

It's not the battery. My battery was replaced in December, and the battery on my previous '04 CS lasted six years and there was never any issue with the locking system. My dealer did a PIWIS reset on the CTT a couple weeks ago but I'm still getting some anomalies on the locking/unlocking. I think I've figured out how to make them repeatable and I'll have them look at it again when I go back in.

Did anyone ever get a definitive diagnosis on this issue? My 06 CTT has also had strange locking operations ever since I replaced the battery a month ago. Shop that replaced it used an aux battery hooked up to the OBD port to retain memory settings while replacing the battery. Now I get the following symptoms:
1. Truck will sometimes spontaneously lock itself after turning off the ignition and removing the key--door may even be open and the car will lock itself and set the alarm.
2. Unlocking using the key fob will unlock all 4 doors, but the tailgate remains locked. Opening a rear door (with no additional activation of the locks) will then unlock the tailgate and allow it to open.
3. Unlocking using the fob sometimes requires multiple presses off the button. The fob gives positive feedback that the button has been activated, and locks "click" but do not unlock.
It certainly seems like a SW problem. Before I reset everything to factory settings as suggested above, I would like to know if anyone ever figured it out.

FWIW, I left everything alone and after another week the locking problem seems to have cleared itself with the exception of #2 above. Definitely seems like something tied to the software settings. I'm gonna leave it alone and hope the remaining problem clears itself, too!

My theory is that if you don't use the Cayenne every day, the battery charge drops to the point where systems start shutting down. You can reset your comfort settings, and they may last a week or two, but that's it. I use a Battery Tender about once a week -- and problem gone -- Amazon has them. I've replaced the battery a couple of times, and it seems to help a bit -- for a short while. Keeping it fully charged works for me, along with replacing the remote battery once a year.

Also, are you sure the tech is plugging into a "charging port" or simply hooking up to the OBD port just to maintain the memory settings?

Regarding the unlock procedure using the fob, there are two user settings to choose when programming the unlock sequence. You can choose between one push of the unlock button for "all-unlock" or two pushes for 1) driver's side door, 2) other three passenger doors including the trunk.
