keyboard in weird keys after water damage

so pretty much, a couple months ago i spilled soup on my laptop and it started acting up. the laptop would turn on, just not the screen. i left the laptop i storage for a while because i didnt think it would work again, but i just went and checked and it turns on :). the only problem is that the keys aren’t really in english anymore? like when i type in “C” is types in “ç”. i cant log into the laptop to try and switch the language because i cant type my password in properly.. what do i do?
