Transferring an already registered domain name involves changing the domain registrar that handles the domain registration service, so after the transfer, you’ll have to manage things like renewal payments or DNS resource record updates through the new domain name registrar. The transfer process itself is standard with most gTLD and ccTLD extensions. Some country-code extensions are more specific and entail 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 safety feature, which is being adopted by more and more domain registry operators. It’s a standard feature supported by all generic Top-Level Domains. If a domain is locked, it won’t be possible to initiate a transfer process, so nobody can even try to snatch your domain name. The domain lock can be removed only through the account where the domain name is registered in the first place and all new domains that support this functionality are locked by default the moment they are registered.
