Keychron has officially announced the P3 HE under its gaming sub-brand, Lemokey. The Lemokey P3 HE is a new TKL gaming keyboard with an aluminium case and toolless disassembly. The case is also stuffed with the standard sound absorbing foams, both between the PCB and aluminium plate and between the PCB and the bottom case. The case, which comes in black or white with matching keycaps, is finished with an electrophoretic coating and has a silicone bean gasket mount to cut out unwelcome reverberation between the plate and case. Unlike Keychron's newer Q HE 8K series keyboards, which user north-pole HE switches—meaning wider compatibility with other HE switches, like the Gateron Jade Pros and Wooting Lekker Tikkens—the P3 HE still relies on the Gateron Double-Rail Magnetic Nebula switches, which limits switch compatibility to other Gateron KS-37 magnetic switches. On a more positive note, the Lemokey P3 HE is priced at $169.99 , which is significantly less than the $239.99 you'd pay for an equivalent HE keyboard from Keychron.

While the Lemokey P3 HE is somewhat similar in many ways to the Keychron Q3 HE, there are some distinct differences. For starters, that quick-release toolless disassembly feature is only found on the Lemokey keyboard, and the P3 HE uses Cherry profile double-shot PBT shine-through keycaps instead of the KSA and OSA profile keycaps that Keychron usually opts for. There is also a double-shot PBT option without shine-through legends, for those who prefer the more subtle look. The backlighting on the P3 HE is north-facing, for improved compatibility with regular shine-through keycaps. Unlike the 75% and 65% P1 HE and P2 HE, the P3 HE doesn't have a customizable rotary encoder. The Lemokey P3 HE has both wired and wireless connectivity, with the 2.4 GHz and USB-C connections offering 1,000 Hz polling, while the Bluetooth 5.2 connection is limited to 125 Hz and can connect to up to four devices. Being an HE keyboard means that Lemokey Launcher offers features like customizable actuation point, SOCD, rapid trigger, DKS, and analog input in addition to the standard remapping and macro capabilities.
