Door locks

No. I know better than that. If I push any of the 3 buttons down when that door is open, it goes down all the way and locks. The button does not go down fully when door is closed therefore not locking.Using the key on either front door will not lock them either when door is closed but will when it's open. My theory is something is binding when the door closes but I can't see or figure out what. And why in blazes is it happening to all of them? They worked, though not good,when I bought it about 18 months ago. I didn't do anything to any of the doors that I recall.
