What does 30 by 30 mm mean for this Euro double cylinder?

This model is sized at 30 x 30 mm, which refers to the cylinder dimensions for the two sides of the Euro style profile. It is designed for use where a 30 mm measurement on each side fits your door lock case. If you are unsure, check your existing cylinder measurement to match the length and ensure correct fit.

Is the satin nickel finish suitable for modern doors and hardware?

Does this cylinder come with keys and installation hardware?

How do I confirm this is the correct Euro double cylinder for my door?

Look for a Euro profile lock cylinder in your current hardware and compare the overall size to the 30 x 30 mm specification.

Is a different finish or key set ever needed for replacement?

For a straightforward replacement, you typically only need to match the cylinder type and size. This product includes three keys, so if you are replacing an existing cylinder and want new keys, you can do so immediately.
