Transferring an already registered domain name entails changing the registrar that provides the registration service, so after the transfer itself, you’ll have to manage things like renewal payments or DNS record modifications through the new registrar. The transfer process itself is standard with most generic and country-code domain name extensions. Some country-code extensions are more specific and entail different procedures, but in the general case transferring a domain entails several necessary steps and one of them is unlocking the domain name. The lock is a safety option, which is being adopted by more and more registry operators. It’s a default feature supported by all generic top-level domain names. If a domain name is locked, it won’t be possible to start a transfer process, so nobody can even attempt to take your domain name. The lock can be annulled only through the account where the domain is registered and all new domains that support this option are locked by default when they are registered.
