1. C-h f local-set-key RET

2. the documentation of local-set-key tells you how to do it:

       The binding goes in the current buffer's local map,
       which in most cases is shared with all other buffers in the same major mode.

   Therefore you should create a buffer local map distinct from the major
   mode map.

3. M-x apropos RET local map RET

4. find a command that lets you create a local keymap.

5. use local-set-key with the new buffer local map.
