So when I bought my car the dealer promised another fob and also 2 spare keys. They’ve had it for a complete day saying they can’t program in another key due to my aftermarket subwoofer 😂. I didn’t realize how incompetent Volvo dealers are. They say it’s creating some sort of interference. I told them to simply pull the fuse then it’s dead. Apparently this is still causing an issue. I could press it since in MECP level 2 certified but I won’t. Main thing is I have 2 working fobs and 2 spares.
