Does warranty cover malfunctioning keyboard?

[ray7777]

I bought this laptop new in October but I accidentally spilled a drink and it has gone into the keyboard. 

Most of the keys work (although a lot are sticky and hard to press) but the CTRL key is broken, and sometimes if you press it, it gets 'stuck' somehow and acts as thought it is being permanently pressed down, and I then can't type anything - for some reason when this happens the windows menu key no longer works and instead you have to press ESC? Restarting it fixes it but it keeps getting stuck somehow and then I can't type anything, all links I click in google chrome open in new tabs, etc. For some reason the on-screen keyboard also does not work when the CTRL key gets stuck. 

I can't afford to replace it and it is still under the warranty it comes with - please tell me whether I can get it repaired/replaced under this?? I need this laptop for all my university work.

The warranty covers only manufacturing defects. 

What you did to the keyboard was Accidental Damage, and that is NOT covered by the warranty.
