That should be easy by following the instructions that came with the remote. The instructions include a code list for various brands. Zenith is a common brand, so it will be included. Just follow the directions for programming the Zenith code. There will probably be more than one, and you will have to try different Zenith codes until you find the one that's best.
If you don't have the owner's guide for your remote, you might be able to find it on-line with a Google search.
