Go to Apple Menu ¿ About This Mac to open the About dialog. Under the words Mac OS X you’ll see the Version number. Click the version number once to reveal the Build number – then click it again to make the Serial number visible.

There is no OSX Product Key - the only such keys are for server licences, or for developer releases.

To reinstall Mac OS X:
Step 1

Insert the Mac OS X Install Disc and double-click the Install Mac OS X icon.
Step 2

Follow the onscreen instructions. In the pane where you select the destination disk, select your current Mac OS X disk (in most cases, it will be the only one available).
Step 3

Click Options. If you want to save your existing files, users, and network settings, select “Archive and Install,” and then select “Preserve Users and Network Settings.” If you want to erase everything on your computer and reinstall Mac OS X, select “Erase and Install.” You can’t recover erased data.
Step 4

Click Continue.
Step 5

Click Customize to select which parts of Mac OS X you’d like to install, or click Install to perform a basic installation (recommended).

As makazaru stated there is no Product Key
