SikaiCase 3-Key Programmable Mini Keyboard – Wired RGB

Three shortcuts, ready for faster everyday work.

The SikaiCase 3-Key Programmable Mini Keyboard is a compact USB-C wired mechanical keypad for copy, paste, cut, editing, media controls, gaming commands and other repeated actions. Choose printed Copy/Paste/Cut keycaps for ready-to-use default shortcuts, or blank keycaps for a clean programmable setup.

Key Features

• Three-key shortcut layout: keep three frequently used commands beside your main keyboard.
• Ready-to-use printed version: Copy, Paste and Cut keycaps ship with those matching default functions, so no initial programming is required for normal use.
• Programmable blank version: blank-keycap variants must be configured in the Windows software before use.
• USB-C wired connection: this 3-key model is wired only and does not support Bluetooth or a 2.4G receiver.
• Software-controlled RGB lighting: select supported RGB colors and lighting effects in the configuration software.
• Red mechanical switches: smooth linear key feel for repeated presses.
• Hot-swappable design: replace compatible mechanical switches and keycaps to adjust feel and appearance.
• Onboard memory: saved key assignments and supported lighting settings remain on the keypad for normal use after configuration.

Choose Your Keycap Style

Copy / Paste / Cut: the three printed keys have matching default shortcuts from the factory. Connect the mini keyboard by USB-C and use those three functions immediately. You can still reprogram them later if required.

Blank Keycaps: no default labeled workflow is provided. Connect the keypad to a Windows computer and assign the three functions in the software before normal use.

Software and RGB Setup

1. Download the software from the SikaiCase Keyboard Software page.
2. Connect the 3-key mini keyboard to a Windows computer with the included USB-C cable.
3. Assign supported key functions or shortcuts and choose the supported RGB lighting effect.

Software requirement: customization is currently completed with the Windows software and a USB-C connection. Mac users should configure the keypad on Windows first. For Mac shortcuts, use the Windows key in the software for Command and Left Alt for Option where applicable.
