Hi Paul
If what you want is access to Keychain and its contents, use the keyboard shortcut-
Command + Spacebar (which brings ups Spotlight) and type in keychain, then hit Enter. Or Finder > Applications > Utilities > Keychain Access app, which takes longer.
You will see all your entries there. You will need your Admin PW to read the passwords.
I have to confess that I've never thought about copying/
moving the contents , but this Apple Article will tell you all about Keychain:

But be aware: Note: Passwords stored in the iCloud keychain are encrypted and stored on your computer and
can’t be copied. To transfer these keychain items to another computer, set up iCloud keychain on the other computer using your iCloud user name and password. The other computer will sync with the iCloud keychain items on your Mac.
Please post back to tell us if this helps.
