Transferring an already registered domain involves changing the registrar that handles the registration service, so after the transfer itself, you will have to manage things like renewal fees or DNS entry updates through the new registrar. The transfer process itself is standard with most universal and country-specific domain extensions. Certain country-code extensions are more specific and entail different procedures, but in the general case transferring a domain entails a few basic procedures and one of them is unlocking the domain name. The lock is a safety option, which is being embraced by more and more domain name registry operators. It’s a standard feature supported by all gTLDs. 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 is registered in the first place and all new domains that support this option are locked by default when they are registered.
