Batter door replacement

Yes, While I have not had that model in my hands, I just started working on a C330. It looks very similar and it is not hard to replace the battery door. You will need a small cross point screw driver. One of the Dollar type stores or Odd Lots type place will have those cheap sets of 6 'jewler' screwdrivers.

I have the 530, You have to remove the 6 screws holding the covers together. The back cover comes off in one piece, you also have to remove the front cover too (which is held with 2 inner screws, you better use a magnitized screwdriver) please use caution not to disturb the inner board and parts.
Then use a thumb tack to push the holding pin completely thru(watch the spring so not to lose it) remove old door replace with new door, remember to replace the spring before pushing the pin and door back in place.....
Good luck, this can be frustrating if you dont have the right tools, and patience!
