Transferring an existing domain entails switching the domain name registrar that provides the domain name registration service, so after the transfer itself, you’ll have to manage things like renewal fees or DNS entry updates through the new company. The transfer process itself is standard with most gTLD and ccTLD extensions. Certain country-code extensions are more specific and involve different steps, but in the general case transferring a domain entails several necessary procedures and one of them is unlocking the domain. The domain lock is a security option, which is being adopted by more and more domain registry organizations. It is a default feature supported by all generic Top-Level Domains. If a domain is locked, it will be impossible to start a transfer process, so no one can even try to steal your domain name. The lock can be annulled only through the account where the domain is registered in the first place and all new domain names that support this functionality are locked by default the moment they are registered.
