There is a small shaft with a disc on the end that goes inside the shutter button. It sounds like someone didn't see that drop out of the shutter button when servicing the camera. There is a bit of grease on the shaft to hold it there so people many times don't even realize it is there until it is not there. You can unbend a paper clip and see if you can fire the shutter by pushing way down.
Thanks for the advice. I did try inserting a piece of rigid wire and it does fire the shutter. It also depresses the shutter button which is not what happens with the release cable attached. I had a quick look at the service manual but didn't see any reference to it. I will take a closer look.

Yes, those little plungers on the bottom of the shutter button tend to fall out just before you put the top cover back on. If you're unlucky, they fall down inside the camera innards. If you're really unlucky, they fall somewhere never to be found.
You say the shutter button works fine, but if you can perceive that you have to press it down just a bit more than you think is right (maybe an extra 1.5mm) then that little plunger is not in its place.
Thanks for getting back to me. I have been using a KM for many years. The button on the K1000 feels normal to me.

My K1000 is a little finicky. It works with most of my cable releases except one of my double cables for macro bellows. It seems the plunger on the cable won't adjust to extend long enough to release the shutter when pushed. My K1000 needs a much further press on the cable plunger than it does on any of my other cameras.
If the length of the plunger is adjustable your cables try making it longer.
Thanks for your help. My cables are not adjustable as for as I can see but I may be able to find a way of modifying one. It probably just needs a competent service tech to look at it. COVID-related movement restrictions make it difficult to get to a service get to one at the moment.
