Side keys and power buttons for Galaxy M.
On many Galaxy M phones the side key also holds the fingerprint sensor, so a faulty button affects unlocking. Match the part to the exact model and test both functions after installation.

New buttons fix stuck power and volume keys.
Stuck, loose or unresponsive power and volume buttons are common on Galaxy M phones after drops. Often only the external key cap is damaged; if the button still does not work, check the power/volume flex cable as well.
