Transferring an already registered domain involves changing the registrar company that provides the domain name registration service, so after the transfer, you will have to manage things like renewal fees or DNS modifications through the new registrar company. The transfer procedure is standard with most generic and country-code top-level domain name extensions. Some country-code extensions are more specific and entail different procedures, 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 adopted by more and more domain name registry organizations. It’s a default feature supported by all generic Top-Level Domains. If a domain name is locked, it will be impossible to start a transfer process, so nobody can even try to take your domain. The lock can be removed only through the account where the domain is registered in the first place and all new domain names that support this feature are locked by default the moment they are registered.
