Transferring an already registered domain entails changing the registrar that provides the registration service, so after the transfer, you’ll have to manage things like renewal payments or DNS resource record modifications through the new registrar. The transfer process 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 name involves several basic steps and one of them is unlocking the domain. The domain lock is a security option, which is being adopted by more and more registry operators. It is a standard feature supported by all gTLDs. If a domain name is locked, it won’t be possible to start a transfer process, so no one can even attempt to register your domain. The lock can be annulled only through the account where the domain name is registered and all new domain names that support this option are locked by default when they are registered.
