"Elite" was also a brand for older television sets. For these older devices, there are "service codes" that can be used to access factory or service menus for diagnostics and repairs. For example, one such code for entering the service menu on the Elite 21ES02 model involves pressing "Menu = menu = Q.view = mute" on the remote control. If you own an older Elite TV, this is the "code" you might be searching for, rather than one for a modern streaming service.
Websites claiming to offer a free activation code are almost always: Elite Tv Plus Activation Code
