Replacing keyboard

Hi

I have a Insprion 2500. Having problems with keyboard and ordered a new one. Is there a online manual for replacing and installing parts for this notebook? Also can I order these parts online? Could not find either. Finally ordered over the phone with a person which I believe was in another country. Wasn't easy to commuicate with her.  Hoping I get the part and it is the right part.

 

Any help would be appricated. Thanks Ron
