Comments as for the tubular latch. If you need to reverse the lock then it's very simple.  Just be very careful when removing the back plate.  This is screwed on but often sticks in place.  Very gently prise-off the plate or you risk loosing the spring on the lock which will fly out and there are a thousand different ways of refitting it the wrong way.  On a couple of units, I removed the deadbolt to file off the sharp edges which was making the bolt stick.
