In the Dead Rising folder, browse to data\controls. In there you'll find 3 text files keymap, mousemap, padmap. You can edit any one of these and remap the controls to what you like.

For example: Changing W to arrow key up -
Open keymap.txt
Go to: COMMAND_KBOARD_EMULATE_LTHUMB_UP( KEY_W, HELD, ....)
and change KEY_W to KEY_UP
you can adapt this for any other mappings you want to change.

Keep in mind that there are other actions assigned to W, such as COMMAND_AI_VEHICLE_ACCELERATE.
To avoid editing them manually, you could use the Replace (CTRL+H) function in Notepad to speed up the process.
Remember, always make a backup.
