Can't open the back of the camera

I can't open the back of a Spotmatic that I just bought. I pull the rewind lever upwards, then a small sound, but nothing happens, it does not open. Any other ways to open it or fix this?

Have you tired to carefully pry it open with the revind lever raised? It could be that the light seals are sticky - happens with age.

If you take off the bottom plate (on most Pentax models, just three accessible screws) you can pry without causing too much cosmetic damage. The rewind knob should be pulled up enough to release the latch, then held up with something, so you aren't trying to rip the latch off too. On some cameras, after removing the bottom plate, you can also remove the bottom hinge pin, which may help. Removing the top plate is kind of involved.

How hard did you have to pry? On my two Spotmatics, it doesn't require too much force. The rewind crank pulls up about 3/8 to 1/2 inch, which disengages the rewind shaft from the film spool. Then, it encounters a spring. You pull up another 1/8 to 1/4 inch or so, against this spring, which opens the latch on the camera back.

When you let go, the spring pulls the rewind crank back to the first position.

You certainly should not need to use any kind of tool. Some people, new to Spotmatics, are not aware that of that spring and think that that is as far as the crank goes.

On mine, once the latch is released, the back pops open, with no assistance. I do not need to pull the back from the camera body.

On his, it appears that the foam has rotted and caused the door to stick. This is a common issue with old cameras before they have been serviced.

Well, it's stuck again, to open it I need to pry the top part of the back with a small flathead.

Bamboo cooking skewers can be your friend with things like this: relatively-thick ones can apply nice even pressure without marring anything, and then you can use em (with a little rubbing alcohol) to clear out the gunk of the bad light seals.
