Transferring an existing domain involves changing the registrar that provides the domain registration service, so after the transfer itself, you’ll have to manage things like renewal fees or DNS resource record modifications through the new company. The transfer process itself is standard with most gTLD and ccTLD extensions. Some country-code extensions are more specific and involve different procedures, but in the general case transferring a domain entails a few basic procedures and one of them is unlocking the domain. The lock is a security option, which is being embraced by more and more domain name registry operators. It’s a default feature supported by all generic top-level domain names. If a domain is locked, it won’t be possible to initiate a transfer process, so no one can even attempt to steal your domain name. The lock can be annulled only through the account where the domain is registered and all new domain names that support this option are locked by default the moment they are registered.
