broken shift key after spilt liquid on keyboard

the other day i spilt some beer on my laptop and then proceeded to turn it upside down and dry it as much as possible

i turned it on late the next day when there was surely no more drink in it and it booted in to safe boot

the computer asked for my password and every time i typed it in it rejected it

after a while i managed to log in but realised my shift key is broken

it is not physically pressed down but as you see everything is in capitals and it prevents me from doing a lot of things on my laptop

does anyone know a way around this that would preferably not involve buying a new keyboard and pay a lot of money to get it fixed?
