Transferring an already registered domain involves switching the company that provides the domain registration service, so after the transfer, you will have to manage things like renewal payments or DNS record updates through the new registrar. The transfer process itself is standard with most generic and country-code TLD extensions. Certain country-code extensions are more specific and involve different steps, but in the general case transferring a domain involves a few necessary procedures and one of them is unlocking the domain name. The domain lock is a security option, which is being embraced by more and more domain name registry organizations. It’s a standard feature supported by all generic TLDs. If a domain name is locked, it will be impossible to initiate a transfer procedure, so nobody can even attempt to register your domain name. The lock can be removed only through the account where the domain name is registered in the first place and all new domains that support this option are locked by default the moment they are registered.
