Or get a Eurolock cylinder that works even with the key in the other

I see I was unclear in my upstream post: Cylinders can be bought either
way. The more expensive ones can be changed over, though this may
require knowledge and/or tools to contain tiny springybits, and/or small
precision bits to exchange. (Disassembly tends to be much easier than
assembly!)

Won't DIY work of that kind invalidate the kitemark, and thus your home
insurance?

I don't know what kind of certification a "locksmith" would need, to
maintain the kitemark status.

The 'works even with a key in' cylinders don't seem to cost much more (or
less).

But are they available at all in the higher security ratings (eg locks
that cost ~£50 each).
