If I disable Registry access, how do I, the Admin, access it again?

I need to disable access to RegEdit for my users, but as Admin I still need to be able to access it.

These are older Windows 2000 boxes that have not responded to a GPO that disables the Registry (not sure why).  

So I have two questions.  One, if I disable Registry access on the workstation itself, will I still be able to access the Registry remotely (open RegEdit on my workstation and connect to the remote workstation).  

Two, if disabling it locally will also disable remote access, is there a way I can remove the Registry restriction once it's in place (since I won't be able to access the Registry).

Thanks in advance.
