How to replace lenovo ideapad p580 keyboard?

I accidentally spill a bit of water inside my keyboard. I wipe it out real quick and the keys were still working, but then when i turned it back on. Some of the keys don't work properly. I open all three screws according to the keyboard location and labels. Unfortunately, i can't get it off. Even worse, the entire number key stop working properly. I try to open starting at the top right corner using my credit card. But, it won't come off. I can't even open it. I feel like there are other screws, but i can't figure it out. My keyboard is pretty much screw up T.T
