Can anyone tell me what the 4th section on the 2009 Vibe remote is supposed to be for? By 4th section I mean that the first three are the lock button; unlock button; panic alarm. There is a 4th section which is just hard plastic, but appears to have a potential use such as remote start. I have the alarm system. Does the standard Vibe key fob only come with lock and unlock buttons, whereas the alarm system has the 3rd button (red panic alarm)?

It's a Toyota remote used in SUVs. The 4th button is to open the trunk lid's window.

You are correct, it is also the trunk release button on Camry's and Corolla's.
