As with many DEI aftermarket alarm system remotes, there are key fobs with different brand logos that are interchangeable. One of these groups is remotes with FCC ID EZSDEI7641.
See Clifford version of DEI remote with FCC ID EZSDEI7641 here.
This remote was used on the CLIFFORD Matrix Venom RS 1.1L alarm system, a system made and marketed by DEI. DEI also used similar remotes with different brand logos on the Python 1400 XPL alarm system and the Viper 160 XVL alarm system. The remotes with this FCC ID are interchangeable and user programmable.
