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?

changing a like for like type cylinder wont

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.

It requires almost zero skills. Just knowledge of the "trick"

None of those sounds like "disassembly", with tiny springy bits.

No I didn't get that comment, mine don't have any springy bits. The locking
mechanism is encapsulated inside a standard fit cylinder and all you do is
swap the cylinder

I had Euro locks at the last house

I have them in this one

Got a locksmith to change the first and having seen what he did was
confident enough to change the one here
