Transferring an active domain entails switching the domain name registrar that handles the registration service, so after the transfer itself, you will have to manage things like renewal payments or DNS entry updates through the new company. The transfer procedure itself is standard with most domain name extensions. Some country-code extensions are more specific and involve different procedures, but in the general case transferring a domain entails several basic steps and one of them is unlocking the domain. The domain lock is a security feature, which is being embraced by more and more domain registry organizations. It is a standard feature supported by all generic top-level domain names. If a domain name is locked, it will be impossible to initiate a transfer process, so no one can even attempt to register your domain. The domain lock can be annulled only through the account where the domain is registered in the first place and all new domain names that support this functionality are locked by default the moment they are registered.
