Slim board guide

Keychron Low Profile Keycaps and PBT Sets

Standard keycap sets don't fit low-profile boards — the switches and stem heights are different. If you own a slim Keychron, the easiest upgrade is one of Keychron's own LSA sets: two low profile PBT keycap sets and a budget ABS one, each with a published list of the boards it fits. For Kailh Choc builds, you need a Choc-specific set instead.

Compatibility check

Keychron K-series: match your exact model and version to the set's list. Older K1, K3, K5 and K7 versions are excluded from the double-shot V2 set.
NuPhy Air and other brands: not on Keychron's lists, so don't assume the LSA sets fit.
Kailh Choc-based builds: use a Choc-specific set.
Logitech MX Mechanical: proprietary, no aftermarket sets fit cleanly.
