Step 2 · Remove the Faucet Handle
Locate the small set screw that holds the handle in place. It's typically hidden under a small decorative cap on the side or back of the handle base. You may need to pry this cap off with a small flathead screwdriver. Insert the correct size Allen wrench into the set screw and turn it counter-clockwise to loosen it. You usually don't need to remove the screw completely. Once loose, lift the handle straight up and off the faucet body.
