Toyota Prius V engine not starting with dashboard lights showing but no Ready light, key fob replaced on Toyota Prius V

Some Toyota Prius V owners report experiencing starting issues when the dashboard lights are illuminated but the Ready light is not showing. These problems can often be attributed to a dead 12-volt battery, which is essential for powering the vehicle's electrical systems. Additionally, hybrid battery issues may contribute to the starting failure, as the hybrid battery powers the electric components of the car. Owners also note that if the key fob battery has been replaced, ensuring its proper functionality is crucial, as a weak or dead key fob battery can prevent the Ready light from activating. Corrosion on battery terminals has been reported to hinder current flow, leading to starting difficulties. Furthermore, a blown electrical fuse can also be a common cause for the vehicle turning on without starting. If basic checks of these components do not resolve the issue, it is recommended to seek assistance from a professional mechanic or a Toyota service center for further diagnosis.
