I know I know I seem obsessed with these damn little black dangles from the key chain now LOL! But on to what I found out and what I have questions on I have found that in 96 for suburban there are two different remotes listed with different part numbers but they seem to be used interchangeably. P/N: 15731442 and P/N: 15725423 They look the same in the pics and are said to work, now that being said I have tried the P/N: 15731442 and its does work. They also share the same FCC ID number ABO0104T which when I looked it up on the FCC web site says General Motors Building 3044 W. Grand Blvd, MC 482-112-257 Detroit MI United States 48202 Lower Upper Frequency Frequency ABO0104T Original Equipment 06/11/1992 315.0 315.0 Ok you bored yet? If not follow along I'm getting to a point There is also remotes listed with other GM PN: but the same FCC ID there is a oldsmobile one that looks just like the above just has a Olds Logo on it. Now the questions If they are the same Freq what makes them unique to one vehicle could you take these other remotes and program them to your vehicle? The reason is some of the others are cheaper and more abundant and might be alternative for folks who need a replacement. So any ideas?
