Transferring an already registered domain name entails switching the domain name registrar that handles the domain registration service, so after the transfer itself, you will have to manage things like renewal payments or DNS modifications through the new domain registrar. The transfer procedure is standard with most universal and country-specific Top-Level Domain extensions. Some 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 security option, which is being embraced by more and more domain name registry organizations. It’s a default feature supported by all generic Top-Level Domains. If a domain is locked, it will not be possible to start a transfer procedure, so nobody can even attempt to steal your domain. The lock can be annulled only through the account where the domain is registered in the first place and all new domains that support this feature are locked by default the moment they are registered.
