Left Shift key issue on external keyboard for MacBook Pro

An unusual question; I am using a MacBook Pro with an external keyboard & monitor. The left shift key will not let me make a capital w but the right shift key will. Is this the end of life for this keyboard?

MacBook Pro 16″, macOS 26.4

re: external keyboard


Try a different keyboard and compare your results...


If you set up some custom shortcut, try disabling that, ref:

Create keyboard shortcuts for apps on Mac



Typically single key issue is a hardware fault.
