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