Transferring an already registered domain name involves changing the domain registrar that provides the domain registration service, so after the transfer, you’ll have to manage things like renewal fees or DNS record updates through the new registrar company. The transfer process itself is standard with most TLD extensions. Some country-code extensions are more specific and involve different procedures, but in the general case transferring a domain involves several basic procedures and one of them is unlocking the domain name. The lock is a security feature, which is being embraced by more and more registry organizations. It is a default feature supported by all generic top-level domain names. If a domain name is locked, it will not be possible to start a transfer procedure, so nobody can even try to take your domain. The lock can be removed only through the account where the domain is registered and all new domain names that support this feature are locked by default the moment they are registered.
