Exterior door, already has two deadlocks, but one of the problems with deadlocks is that they're not very convenient for casual use - i.e. when one wants to just close the door in a way that you'd need a key from the outside but not from the inside.
The classic solution to this on normal doors is, of course, the "yale" lock - which is just a catch.
uPVC doors tend to be a little more sophisticated, and although the "key to open from outside, handle sufficient on the inside" concept is still valid, the locks sometimes combine with deadlock functionality.
I bought a sash lock - which has a handle and a deadlock in the same unit - slightly by mistake. I was somehow hoping that this would give a moderately secure yale-style "shut and go" solution suitable for popping out, while offering a "push the handle up and use the key" for something more secure, and then allowing auxiliary chubb-style deadlocks for maximum security.
Is it possible for me to buy an alternative lock mechanism that has the same centres as the sashlock, which would work in a more Yaley way?
Thinking about it, I'd probably settle for something where the euro-cylinder has a knob on one side and key-hole on the other.
FWIW, the sash lock was something like this:
