Lighting, Light Fixtures, Ceiling and Exhaust Fans - taking a switch out of loop

i live in a bi-level home. there are 3 switches that control 2 lights, one upstairs and one down. i would like to make the downstairs switch work the downstairs light and the landing and upstairs switch work the upper light. how can i take the lower one out of the loop and have it work independently?

Well, first of all, this modification would probably violate code. Code requires that you be able to illuminate the stairs from either end.

Second, this project will not be possible without modifying the wiring in the walls and ceiling. Can you get to the wires and/or are you good with drywall repair?

If you still wish to proceed, we're going to need to ask you a lot of questions. As a start, shut off the breaker, gently pull both switches out of their boxes without disconnecting any wires, and tell us everything you see in precise detail. We'll probably need more information later.

here's more of what's up. we had a hanging light in the foyer. i replaced it with a lighted ceiling fan. there is also a smaller light fixture in the lowest level of the house. since the ceiling fan is so high, i thought i'd put a remote control on the fan. but to work it, i have to have the power on to the fan, thus the lower light is on all the time. not wanting to rip up walls and all, do you have any suggestions on an easier fix? i still need the lower light to work, but don't want it on all the time.

One solution would be to replace the lower light with a remote control ceiling fan (with a light kit) too. The trouble is that this complicates the illuminating of the stairs, which might enourage people to do it in the dark.

It of course would have been better to think about this ahead of time. The best solution in the beginning would have been to leave both lights alone and simply add a new ceiling fan where there was nothing before. That solution is still available if you put the old light back.
