Dear Baffons,
Pockets, special clips, fair weather 'what I do with my keys' routines are all the suggestions are those whose path through life is padded out with pointless tasks and general dithering.
Let me enlighten you...
My bike keys
aside from the main key I have one for the tool box which contains items such as a stop and go repair kit, I also have the alarm fob and a Givi top box key.
Splitting those out to be re connected is a pointless time wasting task, I want to grab my keys and know I have all I need and when I get to where I'm going I want to slip the over suit of and stick it in the decent sized top box rather than the BMW one, I could use the panniers but they are in the garage which is where they stay because you don't want width when you've places to go.
If it's sunny I may not wear the over suit so I don't want to rely having stuff in pockets of a jacket that I may not be wearing...
My only compromise is a combination cable lock which I use if I need more storage space, it goes through the arm of my one piece suit and is locked through the handle bars sometimes it's marks the top yoke as I pass it through
