I assume you are considering buying this remote, as opposed to asking questions about a remote you already have. So here's a link to the user manual so you can look up your devices.

As to the question of whether you can learn everything without using codes, the answer is "no". The learning memory in this remote is designed to be used to program buttons that might be missing from the built in codes, not to program the entire remote.
