I've owned my 2010 Panamera 4S w/60k miles about 8 months and overall it's an awesome car. I've had an occasional issue which so far has occurred only in the Downtown area Chicago. I don't know if the tall buildings create interference in some manner with the alarm system like it can with GPS. But whenever I'm in the downtown area the key fob will not deactivate the alarm system but the doors will open. The first time it occurred it ended up being a 3 hour stressful and embarrassing affair. I was sitting there looking like a doofus with the alarm going off every 5 minutes. Because the car was new to me I was wasn't aware the dummy key could be pulled out and by inserting the key fob the alarm would be deactivated. After walking to a nearby Walgreens and changing out the fob battery didn't solve the issue I ended up calling a tow company to have the car towed. The towing company wouldn't tow the car because it's AWD and the ignition could not be turned on to disengage the transmission. Ended up climbing through the rear hatch to manually release the trunk with the cord hidden behind the hatch light...to disconnect the battery...which solved the issue. I thought it may have been a fluke occurrence but it still occurs...but so far only when I'm Downtown Chicago. After about 2 alarm cycles the dummy key will pull out and inserting the fob has me on my way...but still not convenient. Has anyone else had this issue with an effective solution?

Never an issue with my Cayman BUT, I did have a similar issue with another car and it happened exclusively at this one mall we used to frequent regularly and only there. Apparently there was some kind of signal interference at that particular mall. The key fob would not lock or unlock the car. Had to use my backup key to let myself in or to lock the car. This went on for a year or two and then just as magically, the problem went away. I underststand others, but not all, had a similar problem at that mall as well. I would suggest you try parking at another facility, if possible, to see if it still happens. Good luck.

As odd as that sounds, I experienced a similar phenomenon at a local business in my small town. I parked in a specific area between two buildings and when I returned to my truck it wouldn't start and the dash reported no-key found.

I figured the fob battery had died and fortunately the second business building was a locksmith. I went in to get the battery and he looked at my fob and asked "let me guess? You are parked right next to our building side"?

Turns out there is some kind of frequency in the air in that specific area.

And get this : He grabbed a foil type sunshade and went out to the truck and spread it out holding along the side of the truck. The truck started! But then he stepped away before I put it into gear and the truck wouldn't allow the shifter to move. I rolled down the passenger window and explained. He spread the sunshade again while I shifted into reverse.

Amazing. So I think there's some validity to what you are asking someone to consider.
