I have an Inspiron 5567. Last year some of my keys stopped working so I got the keyboard changed and it was working fine. But now in such a short span, I'm facing the same issue again. Some of the keys (e,d,c, volume keys) are not working and I have to pay 3,500+ in order to get it fixed. As a college student, it's not easy to spend this much on my laptop and this issue is really frustrating.

Please help regarding this issue and suggest some better alternatives.
