LS400 security system...Anyone know where to find tutorials or info on this. I've had car for over a year & just discovered it. Happened to unlock trunk from inside then locked door & lifted trunk lid & alarm goes off until I unlocked door & it stoped. Now I notice security activated red light on dash when I lock door. Thats all I know about it. Just trying to get some info. Thanks
