Intro
Changing the already set regular key, using master account or by using existing regular key.
Video
Topics covered
- Change the already existing regular key by using master key or existing regular key.
- Once we change the regular key, you can not use your old regular keys to sign the transactions of master account.
Update
While changing existing regular key you can still have Fee as 0, if you are signing the transaction using master account, and that the master account does not have lsfPasswordSpend flag enabled. If you are signing this transaction using a regular account, then you always pay the normal network Fee and the transaction fails if the Fee is set to 0.

Final tip: While changing the existing regular key pair, you can use the existing regular private key to replace itself, whereas when assigning a regular key pair to an account for the first time, you have to use the account's master private key to do it.
