In our Elkridge, we have two switches in the main cabinet with all the other switches - one for ODS and one for DS (off-door-side and door-side security lights, respectively).
But, it sounds like you checked there already. We don't have a remote, so you must have a different setup than ours.
Do you have any switches near the door way - something you can reach from outside? We have two switches on the bottom stair to the bedroom - one for the light on the outside stairs, and one for an inside entry light.
Sorry, probably not much help.
