Remove door key from the fob, there is two notches at the top, split it open with flat screw driver. Battery type is CR2032.
Youtube has great videos showing you exactly how to replace your Q60 FOB. The battery is labeled and easily identified. Its either a CR2025 or CR2032. WHen you take it apart you will see.Thx man. Much appreciated.
Seems odd they don’t list instructions or battery type in the owners manual.
