Night latch replacement
Can the existing outside cylinder remain?
It may remain when sound and compatible with the chosen case, subject to the desired key-security changes.

Night latch replacement — planning the work
For night latch replacement, dimensions alone do not define a suitable pane. Glass construction, edge support and the surrounding frame affect the specification and fitting arrangements.
