KeyChains won't sync - how to delete and start over?

[al404]

Hi,

I have an iMac and macbook ( also iPhone and iPad ) and keychain is not syncing correctly

On my iMac i have 940 entry on iCloud keychain, on my macbook 120
On iMac I have an ebay login password, on iPhone i can also find it but not on macbook

I did disable and delete keychain on all my device ( except iMac and apple watch that i guess does not have keychain ) I did the same thing for a sync issue this summer.
I did disable and kept passwords of keychain on iMac.

I did wait a couple of minutes and reenabled on my iMac, macbook and iphone.
On iMac the seem to came back too quickly, in a couple of seconds.

if i search for ebay i can find login detail on iMac and iPhone but not on macbook

I also found this Apple page that explains how to delete keychain from icloud

https://support.apple.com/en-us/HT204085

On your Mac with OS X Mavericks 10.9 and later:
Choose Apple () menu > System Preferences. Click iCloud, then click Account details.
Deselect Allow approving using security code.
Go to each of your devices that are using iCloud Keychain and turn off iCloud Keychain.

I can't find this option I guess an old thing that i can't see anymore in iCloud panel

this guide also explain a similar process

how can i delete keychain from apple iCloud server to sync back again?

Give it time. The reason they came back so quickly on your iMac is that it just copied from your local keychain to iCloud, and then began uploading them to Apple. Even though it's a very small amount of data it can take a while.

iCloud Security Codes are no longer a thing if you use two-factor authentication which will be why you can't see that option.

Do I have to wait before reconnect the other device?

How do I know if keychain did upload everything on iCloud ?
