Transferring an active domain involves changing the company that provides the domain name registration service, so after the transfer, you will have to manage things like renewal fees or DNS entry modifications through the new registrar. The transfer procedure itself 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 entails several necessary steps and one of them is unlocking the domain. The lock is a security option, which is being adopted by more and more domain name registry operators. It’s a default feature supported by all generic Top-Level Domains. If a domain name is locked, it will not be possible 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 is registered and all new domain names that support this functionality are locked by default when they are registered.
