To reset a PS5 controller when it becomes unresponsive, manually reset the DualSense Wireless Controller by turning off your PlayStation 5 completely, then flipping the controller over and locating the small reset hole near the L2 button. Insert a paperclip or pin and hold the reset button for about 5–10 seconds. After releasing it, connect the controller to the PS5 using a USB cable and press the PS button to reconnect. This method helps fix common issues like connection problems, freezing, or unresponsive buttons and restores the controller to normal working condition.
