Answer 1

Alright... I'm pretty sure of this.

1st button is to Lock (but NOT ARMED) & Unlock.

2nd button is to DOUBLE lock and ARM. Double lock will disable the inside door handles to prevent opening of the locked door from the inside when say, a window is smashed.

3rd button is panic button - sounds the alarm immediately.

Answer 2

I believe one button opens the trunk if you hold it down, and the other button turns on the interior lights.

Answer 3

nt sure about what the buttons do, but it looks just like the remote (the way you made it) cool
