Hi again,
I've actually given up on this particular keyboard, and will now use it for the spare keys that I was originally after.
Its successor was the Apple Magic Keyboard It was released the same year as the Wireless Keyboard was discontinued and it is the current keyboard that is sold/used. There were four generations of Apple Wireless Keyboard including: First generation (A1016) M9270LL/A; Second generation (A1255) MB167LL/A; Third generation (A1314) MC184LL/A.

Why did I give up? Well, I realised that the Caps Lock light wasn't coming on (implying a wiring problem within the keyboard itself).
So why am I posting this? Because there are a lot of articles that say that all you've got to do is press the power button throughout the entire process, and there are very few that give the following tip (that worked for me, where all the standard advice failed):
You will need a Bluetooth keyboard (that may still be paired with another device / hasn't been unpaired) and an iMac (or similar), with nothing connected (no mouse, no trackpad, no other keyboard).
Switch the Bluetooth keyboard completely off (press the power button for about 3 seconds).
Turn on the iMac.
Turn on the keyboard (I only needed to press the power button for about 6 seconds before it went into pairing mode, at which point I stopped pressing. Indeed, pressing and holding did not work with this particular 3-battery A1255 keyboard).
The iMac has no input devices attached to it, so it searched for one.. It found my device and correctly recognised it as an Apple wireless keyboard.
More importantly, it attempted to connect - and gave me a 6 digit passcode to enter (which none of the other methods had!). At that point it should be fairly straightforward (don't wait for any sort of pop-up box to type in, simply enter the 6 digits and press return) - and that should be it.
Unfortunately for me, the number keys (some or all) aren't working, but the return key was - so I couldn't finalise the pairing, and kept getting an error message (triggered by the return key).
So there you go. If you've acquired a second-hand Apple wireless keyboard - and the standard set-up assistants aren't getting you as far as the all-important passcode stage, try connecting it to an iMac which has no other input devices attached.
All the best,
M.
