you dont need to deregister it if you have not registered all 8 hand sets with your base unit. Just register the new one and the base will assign a new # for this new.

I have a Panasonic KX-TG6700 base unit and KX-TGA670B handsets. We had a similar problem where we were no longer able to deregister the handset using the handset itself. We wanted to be able to use that slot that the broken phone was still occupyng. The solution that we found in the manual online was to hold down the intercom button for 3 seconds until the "in use" light turned on. Then press and hold the number of the extension you want to deregister until it beeps. At this point the base unit has freed that extension.
