Verified compatibility answer

Can Logitech MX Keys S use Bluetooth and Logi Bolt?

Yes. Logitech documents MX Keys S with Bluetooth Low Energy and Logi Bolt connectivity, plus Easy-Switch across up to three paired devices. Logi Bolt is a specific receiver technology and should not be assumed compatible with older Unifying receivers.

Why this answer matters

A keyboard can be healthy while being paired to the wrong Easy-Switch slot or while the user is trying an incompatible receiver family.

Requirements

What has to be true

  • Use direct Bluetooth on a supported host or a Logi Bolt receiver.
  • Select the correct Easy-Switch device slot.
  • For receiver troubleshooting, verify the receiver is Logi Bolt rather than assuming every Logitech USB receiver is interchangeable.

Verify it yourself

Use this test sequence

Change one variable at a time so you know which requirement made the difference.

  1. 1

    Test keyboard events in DeviceOK after pairing over Bluetooth.

  2. 2

    If Bluetooth works, test Logi Bolt separately rather than changing multiple variables at once.

  3. 3

    Check Easy-Switch slot selection before resetting pairings.

Limits

What this answer does not prove

  • Enterprise/business variants can have different package contents; check the exact SKU.
  • DeviceOK can test key events but cannot provision Logi Bolt pairings itself.
