Transferring an existing domain involves switching the company that handles the registration service, so after the transfer, you will have to manage things like renewal fees or DNS entry updates through the new domain registrar. The transfer process is standard with most domain extensions. Some country-code extensions are more specific and entail different procedures, but in the general case transferring a domain entails a few necessary steps and one of them is unlocking the domain. The lock is a safety option, which is being embraced by more and more registry organizations. It’s a standard feature supported by all generic TLDs. If a domain 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 is registered in the first place and all new domains that support this option are locked by default the moment they are registered.
