How Do You Know When Your 2015 Prius Key Battery Needs Replacement?
You can determine when your 2015 Prius key battery needs replacement by observing signs such as difficulty unlocking or starting your vehicle, a decrease in range, or a warning message on the dashboard.
The key indicators for battery replacement are as follows:
