need to find wall switch remote..does that exist?
I have installed a 'remote 3 way' before. You replace the existing single pole switch with their 'receiver switch'...wires in just like a regular single pole switch. The 'transmitter switch' requires a box to mount it in, and runs off a battery (I think it was a 9 volt). I just took a metal handybox, mounted it to the wall where they wanted it, and installed the 'trnsmtr sw'. No conduit or hard wiring required. I can't remember the exact brand name or anything, and it was bought at Menard's. Menard's is like HD & Lowe's, but they only have stores in the midwest. I don't know if they still carry them or not.
You might ask some of your local electrical supply or lighting stores. Check Wal-mart or Sears type stores too.
Doesn't surprise me about HD or Lowe's. 10% of them can't even find their own parking lot.
