Step 1: Cut out jig
Unless you want to etch a significant amount at a time I would suggest just making a small jig.
Cut out a piece with the holes in it and glue it to a solid piece. This will hold the key chain firmly so its doesn't shift and it will protect the other side.
Step 2: Set up etching
Practice with the fonts and the sizing till you get the look you desire.
Place the keys chains in the jig.
