Transferring an existing domain name involves changing the domain registrar that provides the domain registration service, so after the transfer, you will have to manage things like renewal fees or DNS entry modifications through the new domain name registrar. The transfer process is standard with most domain name extensions. Certain country-code extensions are more specific and involve different procedures, but in the general case transferring a domain name involves a few necessary procedures and one of them is unlocking the domain. The domain lock is a security feature, which is being adopted by more and more domain registry operators. It is a standard feature supported by all generic TLDs. If a domain is locked, it will be impossible to initiate a transfer process, so no one can even try to register your domain. The domain lock can be annulled only through the account where the domain name is registered in the first place and all new domains that support this feature are locked by default when they are registered.
