The local Lexus dealer kept the car for 5 weeks, removed the dash, door panels and reloaded software. Their explanation was "we've never seen this before, don't know what caused it to happen, and don't know how to fix it". So, they turned off the feature (it's not one of the "personalizations" you can select yourself), gave us the car back and said "good luck". Luckily the work they did was covered under warranty. They also took both remotes apart and replaced the batteries. The technician said inside one of the remotes, there was a small "sticker" that he removed that was apparently affixed by the manufacturer, but he doesn't think it was anywhere close to being thick enough to actuate the remote that would in turn, open the windows, the sun roof and unlock the doors just by being in a purse or pocket. Based on the "tight pants" experience others have recorded on this forum, my money is on the problem being caused by the sticker, even as tiny as it was. Electronic devices usually don't just decide to activate on their own without some external cause. This problem hasn't repeated in over a year, so I'm guessing we're in the clear.
It hasn't repeated itself because the dealer turned off the feature...duh.
