Is the keyboard replacable?

Dears,

Is it possible to replace the keyboard of the A1502 macbook pro?

In fact I have spilled some liquid on it.. After hopeless tries tryin to recover I have noticed the following.

If pressing the power button --> laptop no response. In fact no response to any of the key combinations

If disconnecting the battery pins, then plugging in the powef adapter, --> laptop power on . if i connect the battery, I can see the charging icon on the login screen.

On the log in screen I cannot do anything since the keyboard is still irresponsive.

Does this behavior means a keyboard problem? How can I tell that the logic board is not hit?
