I understand your concern -- but we here can do nothing to examine or repair your keyboard.
If the keys are stuck because of some sticky substance underneath them, the typical solution is to remove the keyboard, soak it in some solution that breaks up that substance, dry out the keyboard, and then re-attach it. But we can not provide any detail instructions on how to do the removal because it varies by individual laptop model.
To see if this is a hardware issue, here's some troubleshooting steps you can try: http://support.hp.com/us-en/document/c03738933
If you are experienced at laptop repairs, you can often replace a keyboard for $25 for a new one and a half-hours work. I have done this on older HP laptops.
But, if you're NOT, there is a serious risk of breaking fragile connectors and cables doing this -- so I do not recommend it.
Instead, I would recommend you hunting down a local laptop repair place to have THEM replace the keyboard. Sometimes, on some models, you have to replace the entire top surface of the laptop, not just the keyboard. So you should get an estimate of what is involved before you have the work done.
