Check that your switches are hot-swappable. If they are not, trying to remove them will damage your keyboard.
The mechanical switches are NOT hot-swappable, and the colored stem is smaller and more oblong.
The optical switches are hot-swappable, and they have a larger colored stem which is mostly square.

Is having non-hotswappable keys means we cant disassemble it?

Use a switch puller to remove the switches.
If you have the included switch puller from Keychrone, it may be tough removing said switches.
Each switch has small tabs on the corners to grab and remove them. (The Included switch puller might require extra strength to remove)

BEWARE!!! My Keychron K3 looks exactly like this but the switches are soldered on!! If you just pull (like I did) you’ll break them!

The optical switches (pictured) are hot-swappable, and the colored part of the switch is approximately square. The mechanical switches are NOT hot-swappable, and the colored part is smaller and oblong.

What is the part number or specs for the battery?

Hi Wendy!

I could not find an OEM replacement for the battery, but I did find a battery that a user used in a DIY project with this keyboard. It is not the same one used typically, but this one was reported to give 2x the battery life compared to the OEM one

Hi Tech Guy! The Ebay link is no longer working. Do you still remember the battery model?

Yu Lu - 14 июл 2023 г. Ответить

Hi! This is the "Tech Guy" I did change my username. I do apologize for the broken link. I did find two replacement links and will add specifications for the battery in terms of size, milliamp hours, and voltage
