The 24-year-old Kerber broke Keothavong four times in the second set and then earned the only break of the decider. She will face countrywoman Mona Barthel in the next round.
Earlier Thursday, Serbia's Bojana Jovanovski advanced after defeating Monica Niculescu of Romania 6-7 (6), 6-4, 6-1.
Top-ranked Caroline Wozniacki of Denmark was playing Pauline Parmentier of France later.
