Door lock question

[gooner1]

Should I be able to activate a lock by hand, by moving the part
the locking arm lever fits into.
This is on a Drivers door not connected to a Car and without
a Lock barrel/cylinder fitted.

Talking about the part with the black marking round it in the pic below.

Yes.

If the latch cannot move by hand,how do you expect the key to move it?

I don't Malc, I wanted to know if I could lock a door
without a barrel/cylinder fitted.

All the lock barrel does is to dis-connect the outside handle from the latch....

....and set the deadlock if fitted/instructed.
