One of the FCC IDs that appears on some newer Audiovox key fob remotes is H5OT43. This FCC ID appears on both Prestige and Panther remotes. The remotes have four buttons, including lock, unlock, trunk/remote start, and option buttons.
See Prestige remote at this link.
See Panther remote at this link.
All of the systems that use these remotes are user programmable via the valet button or switch in the vehicle.
