Power button malfunction in Moto G3

[AC Question]

The power button on my Moto G3 has started giving problem suddenly. When I am just touching the button, power off message is coming. I am unable to lock the phone with this button anymore. Everytime same message of power off comes. Any possible solution for this issue

Cleaning with alcohol may help, but repairer attention would probably be wiser.
