Transferring an already registered domain name involves changing the domain name registrar that provides the domain registration service, so after the transfer itself, you will have to manage things like renewal payments or DNS resource record modifications through the new registrar company. The transfer procedure is standard with most generic and country-code TLD extensions. Some country-code extensions are more specific and involve different steps, but in the general case transferring a domain name entails several basic steps and one of them is unlocking the domain name. The lock is a security feature, which is being adopted by more and more domain registry organizations. It is a standard feature supported by all generic TLDs. If a domain is locked, it will be impossible to initiate a transfer procedure, so nobody can even attempt to take your domain name. The domain lock can be removed only through the account where the domain is registered and all new domain names that support this option are locked by default the moment they are registered.
