Try 1-800-remotes Factory original.To buy an exact one or very close to the original.

first you will need to find the model number of the universal. look it up online for the manual and code book. you should probably get the original remote that goes with your unit. type in the model number of your unit in the search on ReplacementRemotes.com and find the OEM remote.

the code should be in the manual of your universal remote. see the brand or maker of your unit and check it on the remote manual

Well...I went to the Jwin website and this is what they have posted as far as using a universal remote:

"jWIN products do not have a series of uniformed universal remote codes, therefore, they can not be provided at this time."
