Xbox Wireless Controller not syncing with 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.

To sync a controller to the Xbox you have to press the sync button on both the controller and the console. If you haven't done that, then it will not sync up. Instructions can be found here

I bought it used froma friend he had it working on his console but when I got it the sync button was pushed in all the way. Then I opened up the contoller to find the sync button has completely broken off and rattles around in my contoller so pressing the
sync button on my controller is not possible

Have you tried syncing your controller with the console? support.xbox.com/.../connect-a-wireless-controller

Hey there Ashford! Is your controller wireless? If so, your controller may not be synced properly with the console anymore. Try turning the console on with the physical button, then try syncing your controller by pressing the sync button on the console and
controller. Once they sync up again, turn your console off and try turning it on with the controller. Let me know the result of this, thanks!
