The privacy lock feature on Gree AC remotes can be useful, but some may want to disable it permanently. However, it cannot be completely removed from the remote. To disable it, simply press and hold both the plus (+) and minus (-) buttons simultaneously for five seconds. It's important to understand the benefits of this feature before deciding to disable it. The privacy lock feature is helpful for households with children or in public spaces as it prevents unauthorized access to the air conditioning settings.
