How Can You Tell If Your 2019 Dodge Key Fob Battery Needs Replacement?
You can tell if your 2019 Dodge key fob battery needs replacement by observing signs of decreased functionality, such as reduced range or failure to unlock or start your vehicle.
Several indicators confirm the need for a battery replacement:
-
Decreased Range: If your key fob no longer functions properly unless you are very close to the car, it may indicate a weak battery. A typical key fob has a range of approximately 30 feet. Any significant reduction in this range suggests the need for a battery change.
-
Unresponsive Commands: If the buttons on your key fob require multiple presses or do not respond at all, this may indicate a failing battery. A fully functional key fob should respond immediately to commands.
-
Warning Light: Some Dodge models have a dashboard warning light that activates when the key fob battery is low. This warning is designed to alert you before complete failure occurs.
-
Physical Signs: If the key fob shows signs of aging, such as corrosion around the battery compartment or a cracked casing, it may also impact functionality. Physical damage can exacerbate battery issues.
-
Battery Life Expectancy: Key fob batteries typically last between 2 to 4 years, depending on usage. If your fob is approaching this age, it may be time to consider a replacement.
Regularly check these signs to ensure your key fob remains functional and avoid being locked out of your vehicle.
