Transferring an already registered domain entails changing the registrar that handles the registration service, so after the transfer itself, you’ll have to manage things like renewal payments or DNS entry updates through the new domain registrar. The transfer process itself is standard with most generic and country-code domain name extensions. Certain country-code extensions are more specific and entail different procedures, but in the general case transferring a domain name involves several necessary procedures and one of them is unlocking the domain name. The lock is a safety option, which is being adopted by more and more domain registry organizations. It’s a default feature supported by all generic top-level domain names. If a domain name is locked, it will be impossible to start a transfer process, so nobody can even attempt to take your domain. The domain lock can be removed only through the account where the domain name is registered and all new domains that support this functionality are locked by default when they are registered.
