My daughter's house has a standard 'yale' type lock on the side
door,
one that slams shut and opens with an ordinary 'yale' key.

When the key has been turned far enough to open the door it needs to
go a *long* way back to extract the key, it's not just back to the
point at which the latch is released, it's 180 degrees or more.

Is this normal or has it been installed wrong somehow? I don't
remember having to 'unwind' other keys so much to get them out.


Sounds wrong.
Sounds somehow like a deadlocking procedure is in use all the
time, rather than as & when required.

Yes, that's possible, it feels like having to wind the bolt out but
isn't actually doing anything. No space in the handle/door bit anyway
for a long withdrawal.


Istr the yale doesn't have a long or deadbolt.

The "double lock" stops it being possible to "slip" the latch
with eg credit card.

But some Yale locks thwart that without an explicit deadlock action being
required.

How?
Maybe it's a BS thing to require a keyed action...

There is an extra "tongue" at the side of the main latch.
When the door is closed, the extra tongue is pushed in and the main latch can't be pushed back.
