A quick search at Google tells me it's not an unfamiliar problem with the 40D. Search for 40d shutter button or Contact cleaning the shutter button in Canon 40D. Also Fix shutter release button not working Canon 30D 40D 50D.
The best is probably to open the camera up and clean the contact. The easiest is probably to put alcohol at the battery place holding the camera upside down. Don't forget to clean the battery compartment before. To get a 40D reparied costs probably more than the camera is worth.

It's fixed! I used some WD40, and contact cleaner. I'm going to get a keyboard air duster, and some alcohol to clean it out better. Thank you!
I suggest that you quit while you're ahead. Introducing foreign objects and substances into what should be a "clean room" type of environment is never a good thing.
Cameras and lenses, cameras most especially, should be cleaned by professionals.
Compressed air can introduce frozen air moisture onto surfaces where it is sprayed, because they sudden drop in pressure is accompanied by a sudden drop in temperature. WD40 and electronics do not mix. There is really no such thing as "contact cleaner", because any solvent leaves residue behind.

Well done for fixing it, but in future do not even think about using WD40 on camera equipment it is not made to be a cleaner or a lubricant it is made to disperse water (hence the WD). Sometimes it can cause more problems than it cures because it dissolves some lubricants and can leave a nasty residue.
If you want to clean out the battery compartment use a little Isopropronal fluid on a brush otherwise as the previous post has stated "quit while you are ahead"

I understand, there were a few times where the shutter button still didn't work so I want to clean it better. I understand that the WD40 was a bad idea won't be using that any more. I am going to try an isoproponal just once more and hopefully it fully fixes it.
Just remember that some (all?) alcohols form a constant-boiling solution with water, which means that you can't get pure alcohol out of an aqueous solution by simple distillation. So what they do is add some amount of an adulterant, notably benzene. That gets the water out, but can leave a trace amount of benzene in the "pure" alcohol. And benzene may not be something you want disappearing into the recesses of your camera. It's one thing to use alcohol to clean lens contacts (of questionable efficacy, but harmless) and another to pour it around the shutter button.
