This video shows you how to remove the emergency metal key from your Volvo key fob remote. These instructions apply to all Volvo with keyless entry including Volvo S60, V60, XC60, XC70, V70, S80, C70, C30, S40, V50, XC90, S70, V40, 850, 200 700 and 900 Series.
This is necessary if your Volvo battery has died and you need to unlock the car. The metal key can be used to unlock the driver's door. Note that newer Volvo cars have a plastic cover over the key hole which can be removed to expose the key.
