Bluetooth is tricky and sometimes the connection can be laggy or broken or something else can go wrong for some weird reason – it could be the motherboard’s fault or the cheap USB transmitter or software issue or other issues.
Here’s a simple flowchart to follow to reset your Keychron keyboard and fix other Bluetooth troubleshooting issues. Thanks to Tim Wolters in the Keychron Facebook Group for creating this.
IMPORTANT: A factory reset does NOT automatically trigger Bluetooth Discovery Mode; you need to do that manually. Therefore the full reset sequence is [FN+Z+J+4sec > FN+1+4sec].

Hi! My K4 keyboard didn’t connect with my laptop and I tried a factory reset without results, but in this chance I used FN + 1 for 4 second after factory resnt and its works perfect!
Thank you 🙂
Mine was caused by a dodgy USB-C hub plugged in to my Mac. Switched it to a better quality one, problem solved.
