Some consumer think that manufacturers only need a single part number to identify a specific automobile remotes. In the case of General Motors (GM), we presume it is because they have multiple design teams for their vehicle makes. So, it’s normal that the same remote can have different part numbers. For Chevy versus Cadillac. Obviously, it should also come as not a surprise that Cadillac dealers often charge more for the very same remote. An example of a GM remote that has numerous OEM part numbers is Remotes And Keys replacement remote 2525A-OEM, which is a 5-button remote with FCC ID OUC60270 that was used on vehicles like, GMC Yukon, Cadillac Escalade, GM SUVs, and Chevy Tahoe.
