Transferring an already registered domain name entails changing the registrar company that provides the domain name registration service, so after the transfer, you’ll have to manage things like renewal fees or DNS updates through the new domain registrar. The transfer process is standard with most Top-Level Domain extensions. Some country-code extensions are more specific and involve different steps, but in the general case transferring a domain name involves a few 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 domain name registry organizations. It’s a standard feature supported by all generic top-level domain names. If a domain is locked, it will not be possible to initiate a transfer process, so nobody can even try to register your domain name. The domain lock can be annulled only through the account where the domain name is registered in the first place and all new domain names that support this functionality are locked by default when they are registered.
