Transferring an existing domain name involves changing the company that handles the registration service, so after the transfer, you will have to manage things like renewal fees or DNS record updates through the new registrar company. The transfer process itself is standard with most generic and country-code Top-Level Domain extensions. Some country-code extensions are more specific and entail different steps, but in the general case transferring a domain entails a few necessary steps and one of them is unlocking the domain name. The 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 won’t be possible to initiate a transfer process, so nobody can even attempt to take your domain. The 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 feature are locked by default the moment they are registered.
