2pcs Battery Door Cover Lid Cap Replacement Repair Part for Nikon D40 D40X D60 D3000 D5000 Digital Camera Repair
$ 6.29
No instruction with product but very easy to replace. Just light twist the old one out and snap in the new one. Worked great. No issues so far on day two. Got the two pack, hopefully never need the second one but better safe than sorry, especially with lots of use and opening/closing to charge battery. Got here quick too!
