Rightthinginess

A bit of a dilemma.  Cleaning up another paint-slathered door lock and the in-built bolt mechanism has seen the light, and now just about operates (and by the time I type this, is fully cleaned, shiny, and operating freely).

However, this is from a door where I'm not entirely sure having a bolt (at child fiddle-with level) is a Good Thing.

So, do I seize it up again?
