Uses a PS/2 keyboard on supported Commodore computers or converts their original keyboards and optional joysticks for a PS/2-equipped host.

The RETRO Innovations store exposed a configuration selector and Add to Cart path on 2026-07-30, with the bare PCB listed at USD 6 and configured kits priced separately. Kits and assembled units are made after ordering and normally take four to five weeks. The maker explicitly treats C=Key as a project rather than a fully supported product because its firmware is not extensively tested or easily upgraded; an AVR programmer is strongly recommended. Use a true PS/2 keyboard because passive USB adapters may not work.

Intercepts the C64 keyboard matrix to add programmable shortcuts, macros, remapping, remote control, and sixteen hardware-control lines.

The maker currently offers revision 4 assembly kits with a PCB, preprogrammed ATmega, and components except connection cables for EUR 30 by email. Kits are made in small spare-time batches and may require prepaid backordering. Version 1.6 firmware, configuration tools, Gerbers, KiCad design files, schematics, and source remain downloadable.
