Hi all,

Trying to help an elderly neighbour with what may or may not be an
actual issue.

She has an Everest fitted Union brand lock mech on her DG ally front
door and says that she normally double locks it at night by turning
the key twice.

Looking at it briefly tonight it seems that it does indeed double lock
and that 'may' cause the deadbolt to move out in two stages.

However, you can't (now?) turn the key completely twice but only 1.5
turns, but you can't then get the key out till you turn it back the .5
turns. It does however seem to take two turns to fully unlock the door
again (or was it 2.5 so you could get the key out again). The point is
just one turn doesn't unlock the door.

Locking it with one turn also works (as in it locks it). ;-)

So, can anyone confirm this 'double locking' on these sort of DG doors
please?

I've pulled the actual Euro lock cylinder and it seems pretty
conventional (as expected) so this would be something that would be in
the lock mechanism itself.

Cheers, T i m

Yes, I've got a double locking aluminium door. Turning the key through
360 degrees the second time does indeed shoot the bolt further into the
frame, making it more secure.

What happens if you turn the key with the door open? Can you then turn
it through two full turns and remove the key? If so, there's something
wrong with the alignment - stopping the bolt from moving fully when the
door is closed.

'Fraid I can't explain why it takes more turns to unlock it than to lock it!
