Transferring an already registered domain involves changing the domain name registrar that handles the domain name registration service, so after the transfer, you will have to manage things like renewal fees or DNS entry updates through the new company. The transfer process is standard with most gTLD and ccTLD extensions. Certain country-code extensions are more specific and entail different steps, but in the general case transferring a domain entails several necessary steps and one of them is unlocking the domain name. The domain lock is a security feature, which is being adopted by more and more domain registry operators. It is a default feature supported by all generic TLDs. If a domain is locked, it will not be possible to initiate a transfer procedure, so nobody can even attempt to snatch your domain name. The lock can be annulled only through the account where the domain name is registered and all new domain names that support this option are locked by default when they are registered.
