Zenith Model H27F36DT Commerical TV Remote Control...

Question

We have about 80 Zenith TV's here at our motel. Forty of them are the Model H27F36DT Commerical TV. It has the CAT-5 plug on the back. We are also using the Zenith Universal Remote (ZN110) here. Our problem is that we would like one code to work for all the TV's or at least one code for all the 40 new ones we just received. Our original 40 use the code 405. Some of the new ones use 701, while the rest of the new ones use 405. Is there any way to reprogram these new ones to either match the 405 code or at least make them all 701?
