The remote manufacturer has the code banks for their remotes. Unfortunately, when they assign manufacturer codes, they have their own system for doing so. We aren't assigned a code among remote manufacturers (such as a standard) to offer as a result.
The best way to get a code, if one is available, is to contact your cable/sat provider.
I need a code for the Time-Warner CLIKR-5 remote for the Samsung Soundbar (HW-C450) on a Samsung TV model LN46C600.
