Z50-70 Laptop - Some of the keys are not working

So I got a Lenovo Z50-70 Laptop.

 

Some of it's keys are not working at all, not even during the boot. I got a dual-boot Laptop (with both Ubuntu 16.04 and Windows 10) and it seems like some of they keys are not working on neither of the installed OSs. Keys that are not working are: z, x, c, v,m, comma, point, enter, return.

 

What I noticed about this keys is that they are possitioned at the bottom row of the whole letter keyboard (except enter).

 

I tried taking out the battery, turn the power off. Restart with the battery or with the power supply. Nothing worked. Laptop's warranty expired as well.

 

Laptop is 2 years old. I had a similar problem with the "1" key a while ago. But the problem there was that the button was being "pressed" continuously. I took it out, cleaned it and still wasn't working. Turned out to be working next day for one reason or another.

 

Nothing happened before/after the last usage of the laptop. Last night while writing some code was working ok. But in the morning it started to act like this.

 

Any adivice is welcomed. Thank you!

Try to re-install keyboard drivers as third party apps can interfere

Keyboard doesn't even work on boot or other OSs. I highly doubt it's a driver issue.

 

Tried to unmount the keyboard and clean the unworking keys. Still same situation.

Try UEFI diagnostics to test the keyboard

and 

You can also  do this step to try and repair any corrupted files.

Go to the command prompt

Right click on it and run as administrator 

Type sfc /scannow and press enter

When it has completed restart your computer

I can't use it, as I can not boot from anything (enter key is not working, so I can't select what option I want - e.g. boot, safe mode, normal startup),

 

/sfc scannow didn't return any errors. Neither did Lenovo  Solution Center.

 

I think I'll have to change the keyboard.
