"Key not recognized" + KESSY problems
#16
Well, I just brought my 2011 CTT with 95k miles to the local shop (not a dealer) and they pulled the error codes - code shows something to do with a sensor and its logic in the trunk area. They will run some research with their Porsche tech contacts and get back to me for an appointment next week. I'll post when I get the next set of diagnoses. Note: no Porsche dealership available to me within an 8 hours drive. Ugh, one car couple. (But gonna get a Q3 so the wife doesn't have to deal with any of the ongoing CTT shenanigans.)

Update (October 2019): went to auto shop who pulled data from the car and in doing so, cleared the system, and the Key Not Recognized error message ceased - for a couple weeks. But now it's back. With a vengeance. Brought car back to shop to pull data again and the following came up in the results (along with other stuff of course):
Rear module 020007: "1 Fault = C11006" which the shop says requires software update from a Porsche dealer because the car is "in partial anti-theft mode" (the shop's words, not mine). That closest dealership is Spokane WA, about 6 hours drive. Have a service appointment scheduled for Oct 21 (2 weeks time). I think I'll lose my mind well before then however with the persistent and constant error message ringing.

Sitting in Porsche Spokane (6 hour drive/50% through blinding snow. Ahh, Autumn in Montana.) Mystery solved, but not the solution to the problem, yet. Tech @ dealer says the rear passenger door handle beneath the rubber housing is corroded. Tried to dry it out and play around with it to no avail. Going to try and simply disconnect the wiring inside the door frame and see if that's a fix ... Sound familiar kvec? : ) If that solves it, I'll let you guys know.
UPDATE: That worked (so far). Car can be locked, but the disconnected door handle won't actually lock. And if someone does open that unlocked door while the car is locked, the alarm will still activate. So, no harm, no foul on disconnecting the door handle. I can order a new handle, but highly doubt that I will. BTW: Bozeman-Spokane-Bozeman made for quite a day.

Hello All, I just got a 2011 Turbo with exact same problem. Key Not Recognized randomly. It is driving me mad!
- Changed battery 3 times on the remote and even put paper behind the battery in case it was not making contact, Nop
- Tried running with key in ignition, Nop
It must be the door handles, which one I am not sure, but I don't mind disabling the button on every single one if possible.
Question; How do you get access to the button to disable it? I see two small screws on the side of the handle
Thanks!

Sounds like "kvec" could answer that. The issue as I understand it could be corrosion inside the handle, specifically the parts that control KESSY. Simply put, the car thinks someone is pressing the rubbery KESSY button constantly. The controls are underneath the rubber protected button located at about thumb print on the door handle. My guys at the dealership went into the door panel, disconnected the wiring of that particular handle. Which door handle(s) exactly shows up in the diagnostics tool analysis. The affected door no longer locks for me, BUT, the alarm will still go off if that door is opened while the car is alarmed. So .. no harm, no foul IMHO (based on where I live.)

brousfh thanks for your reply!
I would love to disable what you did it, sounds like this is a bad design and eventually every handle needs to be replaced.
Open inner door panel or can it be done from outside?
Can you please tell me HOW to gain access to this wire to disable? Is it fairly easy? I had no intention to lock the vehicle with these stupid buttons anyways.

Bro
Wanted to clarify a few things before I try this. Do you have to take the door panel off? And why did you use "Liquid Electrical Tape"? Just to seat the ends of the wires that were cut?
Thanks. I am hoping this works
