There's a simple solution to your problem - the SX-Key NEEDS 5V to program the chip. You probably got lucky programming it the first time with (3) fresh AAA batteries but now the voltage has dropped slightly. To program my Robomedal, I removed the batteries and made 2 jumper wires that connected Vdd and Vss on the SXTech board to the battery tabs on the Robomedal. I made the jumper wires by soldering an alligator clip to each wire (the other end just plugs into the Vdd and Vss header on the SXTech board. The alligator clips attach to the battery tabs on the Robomedal.

Once you have the Robomedal programmed, you can remove the wires and reinstall the batteries. The Robomedal will continue to run until the battery voltage drops to around 3V.
