Dell Inspiron 3521 Keyboard Repeating keys

Hi Members,

I have Dell Inspiron 3521 Laptop for which Keyboard keys keeps on repeating automatically like Delete Key keeps on repeating, page up and page down key gets repeated due to this i have lost much of my data. I have tried uninstalling my keyboard and reboot it but again same problem happens when i Login. I am frustrated by this issue and need solution to resolve it. I have also updated Keyboard drivers but of no use.

Sometime it dont work and some time it get repeated again and again, do i need to change/replace my laptop Keyboard?

Your revert is highly appreciated. 

Thanks.
