Transferring an existing domain entails changing the company that provides the domain name registration service, so after the transfer, you will have to manage things like renewal payments or DNS resource record updates through the new registrar. The transfer procedure itself is standard with most generic and country-code top-level domain name extensions. Some country-code extensions are more specific and entail different steps, but in the general case transferring a domain entails several 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 operators. It is a default feature supported by all generic Top-Level Domains. If a domain name is locked, it will be impossible to start a transfer procedure, so no one can even attempt to snatch your domain name. The lock can be removed only through the account where the domain name is registered and all new domains that support this functionality are locked by default when they are registered.
