Can't unlock passcode lock iphone 5?

Hey ok i'm pretty screwed over here but ill ask for your help.
last night i was out with some friends and droped iphone 5 and accidently ran over it!
well i was lucky and had it in an otterbox but my touchscreen dosent work
i've been having siri do everything for me like place calls.
but here is my question,
My iphone touch screen does not work, i have a passcode lock on iphone,
is there a way to unlock iphone through my computer
or what to do

Added (1). I can still use my phone to place calls. But i can't check my missed calls without my phone being unlocked, and i can't answer the phone cause touch screen doesn't work so if i can get my phone to shut off passvode lock then i can have siri access everything on my phone for the most part.

Yes. You may have to restore it, but you can unlock it through a computer. It doesn't sound like that will solve your problem, but it's worth a shot.

To unlock your iPhone on your computer you have to have iTunes and connect the phone to your computer then you click restore
