Microsoft 2.4 GHz transceiver v9.0 connects a mouse but fails to recognize the keyboard

Test the keyboard with its original receiver on another computer; if the mouse works there but the keyboard still does not, the keyboard itself or its battery contacts have failed, and there is no supported user procedure for re-pairing a Sculpt keyboard to another receiver.^1^

Re-establish the existing connection

Since fresh batteries have already been tested, proceed without repeating that step:

1. Remove the USB receiver from the computer.
2. Wait at least 10 seconds so Windows unloads the receiver.
3. Plug it directly into a different USB port—do not use a USB hub.
4. Check the underside of the keyboard and receiver for a small Reset or connection button. If one exists, press it to reconnect the existing wireless link. Some wireless devices have this control, but Sculpt models do not necessarily provide one.^2^
5. Test typing in a simple application such as Notepad.

Do not attempt Bluetooth pairing: this Sculpt configuration communicates through its dedicated 2.4 GHz USB receiver.

Isolate Windows from a keyboard fault

Connect the same original receiver to another computer and test both devices:

• Mouse and keyboard work: On the original computer, run Windows Update. Then open Device Manager, locate the keyboard/receiver, select Properties → Driver → Update Driver, and restart Windows.^2^
• Mouse works but keyboard does not: Inspect the keyboard’s battery terminals for dirt, corrosion, or a contact that is flattened and not pressing firmly against the battery. Clean only with the batteries removed. A Sculpt-specific report with this exact mouse-working/keyboard-failing symptom identifies battery-contact oxidation as a possible fault.^3^
• Neither device works: The receiver or USB connection is the likely failure point; repeat the test using another direct USB port.

Receiver and replacement limitation

Keep the receiver that shipped with this set. Sculpt receivers are factory-matched to their sets, and Microsoft does not document a supported method to synchronize the keyboard with an unrelated replacement receiver.^1^ A receiver from another keyboard/mouse set should therefore not be treated as a usable replacement.

If the keyboard fails on a second computer while the mouse continues working, request replacement rather than pursuing driver or pairing repairs. Microsoft lists Sculpt keyboards and Sculpt desktop sets among the accessories covered by its warranty-replacement process; warranty verification for these accessories uses proof of purchase and the Microsoft accessory exchange request.^4^
