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