I recently bought a used 1997 Accord EX V6. How can I tell if it has factory keyless entry installed? The dealership only gave me keys, no transmitter. I checked under the dash and there is a light bluish box that looks kinda like it could house a controller directly above the fuse panel, but I pried open too many of these types of boxes in my Taurus, which is why I eventually required a Honda... Thanks.

added later:

The box actually has a stylized imprint that reads "TRW" and a stamp "Honda" + some numbers + "made in USA" (USA??)
