Transferring an existing domain entails switching the domain registrar that provides the domain registration service, so after the transfer, you will have to manage things like renewal payments or DNS entry modifications through the new domain registrar. The transfer procedure is standard with most generic and country-code Top-Level Domain extensions. Certain country-code extensions are more specific and entail different procedures, but in the general case transferring a domain name involves a few basic steps and one of them is unlocking the domain. The lock is a safety feature, which is being adopted by more and more domain name registry operators. It’s a default feature supported by all gTLDs. If a domain is locked, it will not be possible to initiate a transfer procedure, so no one can even try to register your domain. The domain lock can be removed only through the account where the domain is registered and all new domain names that support this functionality are locked by default when they are registered.
