Same problem on more than one door, after they've both worked properly in
the past?

Yes. The first one started it about a year ago (locks are about 5 years old).
It was on a door in the garage that doesn't get used much, so I never did
anything about it. The second door just started acting this way this week.

The problem is definitely with the latch part, as you can not manually push it
in. I'll try dis-assembling the locks and see if the silicon spray helps.
