Hi! I want to put a lock on my back gate. I want for it to be keyed
with a 'yale' style key (whatever the correct name for that is). I
need for it to be lockable/openable from both sides. Now, here come the
curve balls...

The backset of the lock needs to be greater than 65mm preferably more
though, to be fair 100mm would be enough :-)

Because this is just a gate (and the 'Z' frame is only about 1" think)
it will be difficult to fit a standard mortice lock. So I'm thinking
that a rim lock may be best - or, at least, quite a thin lock.

Because I don't want to carry a chunking great chubb key around just
for my back gate, I'm thinking that a suitable new fangled euro lock
may be available

If possible, the lock would also have a normal handle for opening the
gate too (does this make it a 'sash lock'?).

Any ideas out there?

Cheers

Phil
