Hello. I have the need to build a garage door remote. I would like to build the remote with an arduino. I need to get the rf code from another remote that is already programmed to open and close the garage. What do I need in order to capture the rf code from the remote and send it, all with arduino?

This sounds too much like an attempt to build a "code-sniffer" to allow someone to get into the garages of other folks. If you already have a garage door opener, why would you want to build another remote? Good luck getting anyone to help.
However, I (for one) would help you to build a separate garage door opener that attaches to your existing opener (you can connect to the button or to the terminal on the opener itself), and a remote that will activate it.
Garage door remotes most likely use rolling codes anyway.
