Yeah lol, it might have been clearer if I hadn't mentioned “double glazed” and just said “UPVC doors”, because not all UPVC doors have little window panes in the upper half of the door. But if the is a window in the door then it's usually double glazed. The locks are situated on the UPVC part.
Here's a picture of what I meant. _http://www.upvcdoorcompany.co.uk/

OK, so this is basically about the quality of a lock on a storm door that you can break open with a rock?

No not by a rock. As I understand it, the barrel of euro profile locks are so designed that the mid section which twists on the barrel so as to operate the locking/unlocking door mechanism is a weak point which can be snapped if someone gets a wrench and twists the protruding barrel where the key fits, and then gain entry. That's what they call 'snapping'.
Then there's something called 'bumping' where they can stick a thin piece of metal or screwdriver into the keyhole, then sharply tap the screwdriver several times while twisting the screwdriver which can cause the tumblers in the lock to jump into the correct positions so the door can be opened.
These ABS locks are so designed that to stop the snapping in the mid point they've made a weaker point closer to the outside of the door, so if they try 'snapping' it will snap at this new point and the door will stay locked. And to stop 'bumping' they've made one or too tumblers in the lock magnetic and made the corresponding key magnetic in exactly the same place so only the correct key will open the door.
That's my basic understanding of it anyway.
Edit: Now I remember the tumblers are not magnetic but the mechanism is filled with some sort of liquid to stop the bumping.

I think that she means that all someone has to do is break the glass with a rock, reach in, unlock the door.

If you are concerned in security of locks you should definitely see what these guys do.

Look for videos on YT about bump keys.
It turns out that 90% od locks can be picked this way , and it takes seconds ...
