There is no "universal remote code" for a device. The number is just the location in the memory of a particular make and model of remote that the the IR codes are stored. Even the Logitech Harmony remote database doesn't have Madrid codes so your only option is to try and find the importer and see if they will sell you a remote.
Thanks for the response.. Too funny,, just bought a Harmony remote today was going to try it... Now my problem.. there is no way to contact Madrid w regard to getting a remote. Anyone have any contact info? Nothing on google about this brand at all.
If you try to use the Logitech and they don't have the codes they will instruct you to use the original remote to teach them into their database. That's how they add IR codes to it.
If you can find someone selling the same Madrid and they allow you to return it you can use the working remote to program the Logitech and send it back.
