If your 2009 Dodge Charger key fob won’t start the car, you’re in the right place. This frustrating issue can stem from a variety of causes, from a dead key fob battery to more complex problems with the car’s ignition system. We’ll explore all the possibilities and provide troubleshooting tips to get you back on the road.
Common Reasons Why Your 2009 Dodge Charger Key Fob Won’t Start
There are several reasons why your 2009 Dodge Charger key fob might not be cooperating. Let’s examine some of the most common culprits.
Dead Key Fob Battery
One of the simplest explanations is a dead key fob battery. Over time, the battery powering your key fob drains, eventually rendering it useless. This is easily fixed with a quick battery replacement.
Key Fob Programming Issues
Sometimes, the key fob loses its programming and needs to be reprogrammed to communicate with your Charger. This might occur after a battery change or other electrical disruptions.
Faulty Ignition Switch
A malfunctioning ignition switch can prevent your car from starting even with a working key fob. The ignition switch is the electrical component that receives the signal from your key fob and starts the engine.
Weak Car Battery
While seemingly unrelated, a weak or dead car battery can also interfere with the key fob’s functionality. The car needs sufficient power to receive and process the signal from the key fob.
Key Fob Damage
Physical damage to the key fob, such as a cracked case or water damage, can also prevent it from working correctly. Internal components might be broken, hindering communication with the car.

Reprogramming your key fob might require consulting your owner’s manual or contacting a Dodge dealership. Some procedures can be done at home, while others require specialized equipment.
Checking Your Car Battery
Use a multimeter to check the voltage of your car battery. A reading below 12.6 volts indicates a weak battery that may need charging or replacement.

Carefully examine your key fob for any signs of physical damage. If you notice any cracks, water damage, or broken buttons, you might need a replacement key fob.
