Are there any key fob controls that have reasonable range? My buddy has a toy x10 unit (SP switch replacement) that was rated to work "up to
130'. It actually has a range of about 20' and that is while standing in the same room as the receiver. He called and they told him that that was the usual result.
A Google on the key fob gives a number of hits that look the same as his. The load is 300W incandescent lights. The preferred receiver would be a SP toggle switch replacement but other receivers might be OK.
