Wireless keyboard won't connect or pair

This is usually a power, pairing, or Bluetooth-mode issue rather than a broken keyboard. Fresh batteries, re-pairing, and confirming the right connection mode fix most cases.

Symptoms

  • Keyboard doesn't respond at all
  • Computer doesn't show the keyboard in Bluetooth devices
  • Keyboard connects but disconnects repeatedly
  • Pairing worked before but stopped after a restart

Likely causes

  • CommonDead or low batteriesMost wireless keyboards stop broadcasting well before batteries are fully dead.
  • CommonKeyboard not in pairing modeMany keyboards need a button held for several seconds to enter pairing mode.
  • CommonUSB receiver unplugged or in wrong portA dongle-based keyboard needs its specific receiver plugged in, not just any USB port.
  • PossibleBluetooth turned off or already paired to another deviceA keyboard can only actively connect to one Bluetooth device at a time on most models.
  • Less commonInterference or too many Bluetooth devicesCrowded 2.4GHz environments can prevent a stable pairing handshake.

What to do

  1. Replace the batteries with fresh ones, since low power is the most common cause of pairing failure.
  2. Confirm the USB receiver (if the keyboard uses one) is plugged directly into the computer, not a hub, and try a different port.
  3. Turn the keyboard off and back on, then hold the pairing button until its light blinks to enter pairing mode.
  4. On the computer, open Bluetooth settings, remove any old entry for the keyboard, and add it again as a new device.
  5. Move any other Bluetooth devices or Wi-Fi routers farther away temporarily to rule out interference.
  6. Try the keyboard with a different computer or the receiver in a different USB port to isolate whether it's the keyboard or the computer.
  7. Restart the computer, since a stuck Bluetooth service can block new connections.

When to call a pro

If the keyboard won't pair with any device after fresh batteries and a factory reset (check the manual for the reset steps), the internal radio has likely failed and it needs replacing.
