All universal remotes do not use the same programming codes. Manufacturers have different methods for inputting their information, which results in each having unique codes.
Even two remotes of the same brand may have different codes for the same model device. The exceptions to this are the GE remotes.
For users who have misplaced instruction manuals and do not know how to reprogram their remotes, most brands offer a search function on their universal remotes where users can possibly locate codes that work. If that is not an option, remotecentral.com hosts a collection of universal remote control manuals. Alternately remote control manufacturers, such as Philips, provide content on their official websites to help remote users through the reprogramming process.
