Sometimes these fob's fail or the module responsible for getting the signal from the fob fails. Do you have multiple remotes that do not work or just one? If there are more than one then you probably need to replace the module. However, to determine this we need to monitor it with a scan tool. I attached the testing that we need to follow.
Unfortunately with this being a newer vehicle the options are limited for do it your selfers but if you have access to a tool that can read the modules then we can figure this out.
