Re: Can't open battery compartment.
there are two ways to fix this.
1- remove the bottom cover, take the rubber seal off from the battery compartment, remove the battery then soak the bottom cover in vinegar overnite. this will remove all corrosion. remove the battery cap and clean the threads. completely dry the cap and bottom cover, apply WD40 to battery cover threads. clean battery contact with pencil eraser ( carefully ). reinstall the rubber seal, replace bottom cover.------ best fix.
2- this may not work but it's worth a try. just apply ( carefully ) WD40 around battery cap and let it set for about an hour, re-apply and wait another half hour. If this doesn't work refer to # 1

Many possible causes. First is that the battery is in upside down. Next you should remove the bottom cover 3 screws and the bottom cover. You can then remove the battery compartment and check for battery leakage corrosion on the wire on the bottom. If the corrosion is too bad it will wick up the wire to the top circuit board. You would have to remove the front and top covers to replace the wire.
the least likely cause would be the failure of the photocell that turns on the meter.
finally, if the camera has been impacted the meter may be broken. Without a battery the needle should rest In the middle of the scale (half way between top and bottom, in the cut out). If, when you put in the battery and the needle goes either to the top or bottom and stays there, and stays there no matter what setting, it is a sign the meter is broken.
To repair this camera will be well over $100; my opinion not worth it. You would be better served purchasing another camera of the same type from ebay. An alternative terrific camera is the Pentax K1000, better yet K1000 SE. The SE has a split viewfinder, easy to focus. The K1000 have microprism that are more difficult to focus with especially in lower light; need good eyes. Then there is the Pentax K2, that at the time was their top of the line camera. All three cameras can be purchased for about $100-ish. Most will come with the Pentax 50mm f/2.0 lens.
there are three different possibilities. remove three screws, take off bottom cover. remove three screws of battery holder, lift to see if the battery wire has corroded or broken off. solve by extending wire and resoldering. the next involves removing the top cover to see if the meter coil is dead,if this is the case it needs to be replaced, or there is a broken lead somewhere. usually it is cause no. 1.
clean the battery cover and contact with a pencil eraser making sure the cap threads are also clean.
this is a fairly expensive repair if the meter or circuit board needs replacing ( no new parts are available ).
if the meter still does not work, and the K1000 is in good working order buy a inexpensive hand held light meter.
