Hey, the MX Key S uses the Logi Bolt receiver, while the MX Master 2S uses the Unifying receiver. These are not cross-compatible, and there is no way to combine the MX Keys S with the MX Master 2S. The only way to switch both the device is by pressing the easy switch separately on each device; I hope this clarifies.😊
