Logitech MK320 Keyboard Receiver Lost: What You Can (and Can’t) Do

Losing the USB receiver for the Logitech MK320 keyboard and mouse combo is frustrating, especially because the keyboard will not work at all without it. Unlike many Logitech office keyboards, the MK320 does not support Bluetooth or Unifying receivers, which limits your recovery options.

This guide explains exactly what receiver the MK320 uses, why most replacements will not work, and what your realistic next steps are.

⚠️ How the Logitech MK320 Actually Connects

The Logitech MK320 uses a dedicated 2.4 GHz wireless nano receiver that is factory-paired to the keyboard and mouse.

Key facts:

  • ❌ No Bluetooth support
  • ❌ Not compatible with Logitech Unifying
  • ❌ Not compatible with Logitech Bolt
  • ❌ Not compatible with Lightspeed
  • ✅ Works only with its original MK320 nano receiver

Once that receiver is lost, the keyboard and mouse have no way to communicate.

🔍 Why a Unifying Receiver Will NOT Work

This is the most common mistake.

Although many Logitech keyboards use Unifying receivers, the MK320 is not part of the Unifying ecosystem.

That means:

  • You cannot pair the MK320 keyboard to a Unifying receiver
  • Logitech Unifying Software will never detect it
  • The orange Unifying logo receiver is useless for this model

The MK320’s receiver uses an older, fixed pairing protocol that cannot be re-paired in software.

❓ Can You Buy a Replacement Receiver?

Yes.

Important limitations:

  • Logitech does not sell replacement receivers for non-Unifying devices
  • Third-party or generic 2.4 GHz receivers will not work
  • Even another MK320 receiver usually will not pair unless it came from the same original combo

The keyboard and mouse are typically hard-paired at the factory.

🛠️ Things You Can Still Try (Low Success, But Worth Attempting)

These rarely work, but if you already have access to parts, you can try:

  • Testing the keyboard with a receiver from an identical MK320 combo
  • Contacting Logitech support to see if they have legacy stock (rare)
  • Checking local electronics recyclers for a complete MK320 set

Results vary, and success is uncommon.

🔁 The Practical Reality: Replacement Is Usually Required

Because the MK320 is:

  • Non-Bluetooth
  • Non-Unifying
  • Not software-pairable

Losing the receiver usually means the keyboard portion is permanently unusable.

In most cases, the most cost-effective solution is:

  • Replace the entire keyboard/mouse combo, or
  • Upgrade to a modern Logitech combo that supports Unifying, Bolt, or Bluetooth

🔄 Better Logitech Alternatives (Receiver Loss Friendly)

If receiver loss is a concern, choose models that support re-pairing:

These allow you to replace the receiver without replacing the keyboard.

  • It uses a non-Unifying, factory-paired nano receiver
