Sorry if this is long, but just trying to get thoughts on this if anyone has experienced this or something similar.
I had 2 keys and buttons on each of them wore out so that I could no longer lock or unlock the doors remotely, only using the keys in the door, that gets annoying as you may know. I had replaced the alarm computer in ~2008 and at that time didn't know the option to unlock the doors when opening the trunk was not set, so that wasn't an option either. I purchased 2 new keys from Suncoast, best deal around BTW. Anyway I took them to a local dealer in April/May to have them programmed, when I tried to open the rear trunk, nothing, front trunk and doors are fine. So I called them and took the car back in, they found a TSB stating that using the PIWIS on older 968s to program keys produces basically the symptoms I have where I can't open the rear trunk. Also of note, when putting the top up and closing the latch, the windows don't lose anymore, used to, but not since programming the new keys. This may be a setable option, but I mention it because something changed. The TSB stated an update for June 6th. So took the car back in, they had it for 3 hours and came back with a ground problem, system sees the key, red light flashes when pressing the button, no ground sent to pop the trunk. They ran a bypass wire and then were able to get the key to op the trunk. Also, system has no clue if passenger door is locked or not (This I knew ongoing problem, I had a new door lock assembly and was waiting to put it in). Anyway I took the car and told them, maybe the passenger door lock somehow had something to do with it and I'll get it replaced and see if the problem persists. I replaced it, no change. Then the dealer got pissy with me about fixing my own stuff, they only knew me from just the past couple of months and I could have done things to the car since April. (Previously I had service there but thy apparently have no records of me ever going there before). Anyway I pretty much went off on them and gave them a piece of my mind, They backed off and took the car back and gave me a loaner. They have had it for three days and off and on have been I guess attempting different things to figure this out. I am picking the car up later as I am leaving for vacation tomorrow and they will resume when I get back.
Here are the facts:
1. Old keys opened trunk
2. New keys don't after programming
3. Windows used to go up when I closed the latch after putting the top up, they no longer do, other than that the windows all work fine, I am sure there's an option in the system to set that as a preference, I only mention it as a troubleshooting item, as I have said something changed when the car was programmed by the bad PIWIS system.
4. All of this changed when new keys were programmed using a bad PIWIS software version
5. We know there was a TSB about the PIWIS software and key programming, who knows what else was affected when attempting to program keys with the bug in the software?
Any thoughts?
BTW I have a copy of the TSB.
Thanks,
