Transferring an already registered domain entails changing the registrar company that provides the registration service, so after the transfer itself, you will have to manage things like renewal payments or DNS updates through the new domain name registrar. The transfer procedure is standard with most gTLD and ccTLD extensions. Some country-code extensions are more specific and entail different steps, but in the general case transferring a domain entails several basic procedures and one of them is unlocking the domain. The lock is a safety option, which is being adopted by more and more registry organizations. It’s a standard feature supported by all generic top-level domain names. If a domain name is locked, it will not be possible to start a transfer process, so no one can even attempt to register your domain name. The lock can be removed only through the account where the domain name is registered and all new domains that support this option are locked by default when they are registered.
