How I planned to keep my keys, good or stupid?

LOL, absolutely you've tried your best but I think writing them on a steel is better, hard drive and flash drive could easily get corrupted and writing them on your wordrobe might seems safe now but anything could take anyone there, you never can tell. Circumstances might take someone there. So stainless Steel is the best.

Keeping it in a different location can be confusing sometimes which skip the mind. It better to place it in a good offline location that is safe ,that can be reach at anytime that it is needed than to just keep it in many locations that you may not have time to secure it well .
