Keychron K5 QMK V2
QMK
- Supports QMK and VIA open-source firmware for extensive key remapping and macros.
- Includes enhanced IXPE, EPDM, and latex acoustic foams for a refined typing sound.
- PCB mount style and redesigned stabilizers for a more consistent feel.
- Compatible only with specific low-profile mechanical switches (Keychron Milk POM or Gateron), not optical switches.
- Full-size layout is not portable.
- Uses ABS keycaps, which may develop shine over time.
Get the
Keychron K5
- Offers a choice between low-profile Gateron mechanical switches and low-profile Keychron optical switches.
- Vendor reviews praise its quiet operation and build quality.
- Hot-swappable option is available for the optical switch version.
- Lacks QMK/VIA firmware support, limiting software customization.
- Uses a tray mount style, which may feel less uniform than PCB mount.
- Only lists ANSI layout support, no ISO options.
Your decision hinges on software freedom versus switch variety. The Keychron K5 QMK V2 is the definitive upgrade for enthusiasts, delivering superior firmware customization, a more refined internal build with acoustic foams, and broader layout support. Choose the original Keychron K5 if you specifically want the option for low-profile optical switches and do not require deep programmability, potentially at a lower cost.

What will you mostly use it for?
The Keychron K5 QMK V2 is the clear choice for users who prioritize customization, whether for gaming latency, programming macros, or content creation workflows, thanks to its advanced firmware. For standard office use, both keyboards are functionally similar, offering quiet low-profile typing and wireless convenience. The original K5 remains a contender primarily if you specifically want its low-profile optical switch option, which the QMK V2 does not support.
Pick the Keychron K5 QMK V2
- The K5 QMK V2 specifies a 1000 Hz polling rate in wired mode for lower latency.
- Its vendor description claims the latency is 'hardly noticeable even in competitive games'.
- The PCB mount style may offer a more consistent typing feel across the board.

“Genuinely happy with the keyboard. Had a low-profile one from another brand that has been used for 12+ years, and it degraded over time. This K5 feels very good. Still have to get used to the distance between the "primary," arrows, and numpad blocks, but…”
“Got this keyboard so I could keep my K5 Pro at work and this one at home. Both are the RGB version with brown switches, the K5v2 is quieter than the Pro and just as good to use. It also reports battery state over Bluetooth, which is a nice QoL improvement…”

Keychron K5 QMK V2 vs K5: your questions
The Keychron K5 QMK V2 adds support for QMK and VIA open-source firmware, includes enhanced acoustic foams (IXPE, EPDM, latex), and uses a PCB mount design. The original K5 lacks these firmware and foam features, uses a tray mount, but offers a low-profile optical switch option the QMK V2 does not support.
No. According to its vendor description, the K5 QMK V2 is compatible only with Keychron Milk POM low-profile mechanical switches or Gateron/Keychron low-profile mechanical switches. It explicitly states QMK does not support low-profile optical switches.
Yes, a hot-swappable version of the K5 QMK V2 is available. The vendor description specifies this is for the 'RGB Backlight (Hot-swappable)' version, allowing you to change compatible mechanical switches without soldering.
Both keyboards are compatible with macOS and include keycaps for Mac layouts. The K5 QMK V2's vendor description specifically notes it has the same multimedia and function keys as Apple keyboards and allows you to configure different keymaps for Mac and Windows within its QMK firmware.
The Keychron K5 QMK V2 has a polling rate of 1000 Hz in wired mode and 125 Hz in wireless mode, as stated in its vendor specifications. The original K5's polling rate is not specified in the provided information.
A customer review for the original K5 mentions that the aluminum body version does not have collapsible feet, which some users found disappointing. The vendor description for the K5 QMK V2 lists three adjustable typing angles (3.37º, 4.36º, 6.56º).
Yes. With its QMK and VIA firmware support, you can remap any key, create layers, and program macros. The vendor states you can customize each key using the Keychron Launcher web app without installing software.
Both are described as quiet. The K5 QMK V2 has dedicated acoustic foams to enhance sound, while customer reviews for the original K5 also call it 'whisper quiet.' The choice of switch (e.g., Red, Brown) will have a greater impact on noise level than the model.
Yes. Both keyboards feature north-facing RGB LEDs with shine-through ABS keycaps, allowing backlighting to illuminate the key legends.
Both the Keychron K5 QMK V2 and the original K5 are listed with a 2000mAh battery. Actual battery life will depend on usage patterns, backlight brightness, and the connection mode (wired vs. wireless).
The original K5's suitability for gaming is not detailed in its specs regarding latency or polling rate. The K5 QMK V2 is explicitly marketed for gaming with its 1000 Hz wired polling rate. For competitive gaming, the wired mode of the K5 QMK V2 is the more documented choice.
Neither keyboard includes a wrist rest in the standard package. However, both vendor pages list compatible silicone palm rests as separate, frequently bought-together items.
