Transferring an existing domain name entails changing the domain name registrar that provides the domain name registration service, so after the transfer itself, you will have to manage things like renewal payments or DNS entry modifications through the new domain registrar. The transfer procedure is standard with most universal and country-specific TLD extensions. Some country-code extensions are more specific and entail different steps, but in the general case transferring a domain involves a few 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 registry operators. It’s a standard feature supported by all generic top-level domain names. If a domain name is locked, it will not be possible to initiate a transfer procedure, so no one can even try to steal your domain name. The lock can be removed only through the account where the domain name is registered and all new domain names that support this functionality are locked by default when they are registered.
