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?

putting in a less secure cylinder might



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

changing a cylinder in an open unlocked door is easily DIY-able.

I should have said "unlock-able"
