Controllers won't sync up with Series X console.

Sync the Controller:
To sync a wireless controller with your Xbox, follow these steps:

Press the Xbox button on the controller to turn it on.
Press and hold the small sync button on the front of the Xbox Series X console (located near the USB port).
While holding the sync button on the console, press and hold the sync button on the controller (located on the top near the Xbox button).
Release both sync buttons when the controller's Xbox button starts flashing. The controller should now be synced with the console.

Have you tried syncing it using a USB cable? If it won't sync that way either, does it work wired?

Do you have a friend with an Xbox One/Series console? If so, try your controller on their console and their controller on your console. That will narrow the issue down so you know if it's the controller or console that's at fault.

Hi,

If you're attempting to do what I think you you are, it won't work. As soon as you connect a cabled Xbox One or Series X|S controller to a different USB connector it will try to data sync/connect to that device and will disconnect from the previous device. This is why it is recommended that you charge the controller during play directly with the console.

Having a similar issue myself. Recently got 20th anniversary controller. My son changed the batteries and it won't work now. It'll turn on the console but won't control anything.

I synced it with my phone and it works. After that, I re-synced it with the console. It appears to sync, but no functionality. Won't show up as a connected device either.

Update: I just got it to work. Multiple re-sync attempts and leaving the console unplugged for about ten min.

I'm sorry you're experiencing this issue with your Xbox Series X controller. Here are some possible solutions you could try:

Restart your Xbox console: Press and hold the power button on your Xbox console until it turns off. Next, disconnect the Xbox Series X from its power source. Turn off the Xbox controller and remove its batteries. Finally, connect and turn on your Xbox Series X.

Restart the controller: Press and hold the power button on the controller for several seconds until it turns off. Then turn it back on.

Pair the controller with the console again: Press and hold the sync button on the console until the power button flashes. Then, press and hold the sync button on the controller until the lights on the controller flash.

Best regards.
