Hopefully an easy question.... What does the grey button on my 3 button remote do for my TH Solara wagon?? I bought the car second hand and the original remote was no good, I bought a new one on ebay and it is working, but I still dont know what the small grey button does!

Small grey button pops the boot if you press it twice on sedan models. Don't know about wagons.

Opens the boot.

panic alarm also

any button is the panic alarm, as long as you hold it for 5 secs

Serves no real purpose other than additional panic button
