Transferring an already registered domain name entails changing the registrar that provides the domain name registration service, so after the transfer itself, you will have to manage things like renewal fees or DNS modifications through the new domain name registrar. The transfer process itself is standard with most Top-Level Domain extensions. Certain country-code extensions are more specific and entail different procedures, but in the general case transferring a domain involves several necessary procedures and one of them is unlocking the domain. The domain lock is a safety feature, which is being embraced by more and more registry operators. It’s a default feature supported by all gTLDs. If a domain is locked, it will be impossible to start a transfer process, so no one can even try to take your domain. The domain lock can be annulled only through the account where the domain is registered in the first place and all new domains that support this functionality are locked by default the moment they are registered.
