A connected controller can still have remapping, game-specific input, outdated firmware or physical button failure. Test in Xbox Accessories before replacing it. Open the Xbox Accessories app or the controller settings and reset the button mapping to the default. Test the same buttons in the system menus and in a second game before changing anything.
Differential
Likely causes of “Xbox controller connects but some buttons do not work”, and how to tell them apart
- 1
A custom button mapping is changing what the buttons send
What separates it A button seems dead in games but works in the Xbox home screen, and a remap or an accessibility mapping is active.
How to confirm Open the Xbox Accessories app or the controller settings and reset the button mapping to the default.
- 2
A game profile or an in-game control setting is set differently
What separates it Buttons work in menus and one game ignores them, while another game works normally.
How to confirm Test the same buttons in the system menus and in a second game before changing anything.
- 3
The controller's firmware is out of date or a wireless glitch drops inputs
What separates it Inputs drop when the controller is wireless and work when it is connected by cable.
How to confirm Update the controller's firmware and compare wired and wireless behavior.
- 4
A worn or dirty button contact is not making a clean connection
What separates it The same button fails in every game and in the controller test, and it feels different when pressed.
How to confirm Use the controller test in Xbox Accessories to see whether the button registers at all.
Before you touch a setting
Record this first — changing settings destroys the evidence
- Which buttons or sticks fail, and whether they fail in the system menu as well as in a game.
- Whether the controller is wired or wireless and the firmware version shown in Accessories.
- Whether the same controller works on another console or a PC.

ReversibleOpen the controller test and check every button/stick outside the affected game.
Run the smallest isolation test
ReversibleRemove custom mappings, update controller firmware and test wired versus wireless.
Correct only the proven cause
ReversibleCorrect the game profile or repair/replace the controller when the same control fails in the hardware test.
Verify before changing anything else
ReversibleRetest in system menus and two games after restart.
Stop boundary
When this stops being a self-service repair
- !Repair or replace the controller when the same control fails in the controller test on more than one device.

Common questions
How do I test whether an Xbox controller button is broken?+
Use the Xbox Accessories app or the controller test screen. If the button registers there but not in a game, the fault is a setting; if it does not register, it is the controller.
Why do some buttons fail?+
Dirt, wear or firmware.
Is it the game?+
Test in another game.
Should I clean it?+
Gently, with the controller off.
