While on this subject, noticed that noone has mentioned my pet peeve so close to this very issue. That the "Panic Button" is located directly on the off side of the rear window release on the remote. So if you use the most obvious method to depress the window button (pinch the remote with thumb and fore finger) you stand a good chance of triping the blasted "Panic Button".
Your horn is honking, the lights are flashing, you are standing next to this rig in the middle of a parking lot....surrounded by strangers who now think you are trying to steal this Matrix. I love Toyota quality, but I have to suspect that there are mysterious forces at work down there that secretly wants to punish the customers.
