Transferring an existing domain entails changing the domain name registrar that provides the registration service, so after the transfer itself, you’ll have to manage things like renewal payments or DNS resource record modifications through the new registrar company. The transfer process itself is standard with most universal and country-specific Top-Level Domain extensions. Certain country-code extensions are more specific and involve different steps, but in the general case transferring a domain involves a few basic steps and one of them is unlocking the domain name. The lock is a security feature, which is being adopted by more and more domain registry operators. It is a default feature supported by all generic TLDs. If a domain name is locked, it will not be possible to start a transfer procedure, so no one can even try to steal your domain name. The lock can be annulled only through the account where the domain is registered and all new domain names that support this feature are locked by default when they are registered.
