Experiencing issues starting your Dodge Dart can be frustrating, especially when your key fob seems to be the culprit. While modern vehicles like the Dodge Dart are designed for keyless convenience, a malfunctioning key fob can leave you stranded. Interestingly, our experience with a long-term Dodge Dart test vehicle highlighted a peculiar issue – the car running even after the key fob was removed from the ignition and turned to the “off” position, as noted by managing editor Justin Hyde. This unusual event underscores the importance of understanding potential key fob problems and knowing how to react when your Dart doesn’t start as expected.

If you find yourself unable to start your Dodge Dart because of a suspected key fob issue, here’s a step-by-step troubleshooting guide to help you get back on the road.
Understanding Your Dodge Dart’s Key Fob System
The Dodge Dart, depending on the model year and trim, utilizes a sophisticated key fob system that goes beyond just remote locking and unlocking. It’s integral to the vehicle’s ignition system. Typically, the key fob needs to be present and functioning correctly for the car to start. While some Darts may have a traditional ignition slot where the fob is inserted, others might feature a push-button start system that relies entirely on the fob’s proximity and signal.
Common Key Fob Issues Preventing Your Dodge Dart From Starting
Several factors can prevent your Dodge Dart from starting when a key fob is involved:
- Dead Key Fob Battery: This is the most common culprit. Like any electronic device, your key fob runs on a battery that will eventually need replacing. A low or dead battery weakens the signal, potentially preventing the car from recognizing the fob.
- Key Fob Signal Interference: Strong radio frequencies or electronic devices nearby can sometimes interfere with the key fob’s signal, preventing it from communicating with your Dodge Dart.
- Key Fob Damage: Physical damage to the key fob, such as from drops or exposure to moisture, can damage its internal components and render it non-functional.
- Vehicle Battery Problems: While the issue might seem like it’s the key fob, a weak or dead car battery can also prevent the car from starting, even if the key fob is working perfectly. The car’s computer system needs sufficient power to recognize the key fob and initiate the starting sequence.
- Receiver Issues in the Vehicle: In rarer cases, the problem might lie within the Dodge Dart’s receiver module, which is responsible for detecting the key fob’s signal. If this module malfunctions, it won’t recognize the fob, regardless of whether the fob is working correctly.
Troubleshooting Steps to Start Your Dodge Dart
Here’s how to troubleshoot and potentially start your Dodge Dart if you suspect a key fob problem:
-
Check the Key Fob Battery: The first and easiest step is to replace the battery in your key fob. Refer to your owner’s manual for the correct battery type (usually a CR2032) and instructions on how to open the fob. After replacing the battery, try starting your Dart again.
-
Try the Mechanical Key (If Applicable): Some Dodge Dart models come with a physical, mechanical key hidden inside the key fob. Check your owner’s manual to see if your fob has this feature and how to access the mechanical key. If you have a mechanical key and a traditional ignition slot, use it to manually unlock and start your car. This will bypass the electronic key fob system and help determine if the problem is indeed with the fob or elsewhere.
-
Proximity and Position: Ensure you are inside or very close to your Dodge Dart when attempting to start it. For push-button start systems, try holding the key fob directly against the start button while pressing it. This can sometimes help establish a connection if the signal is weak.
-
Check the Vehicle Battery: If replacing the key fob battery doesn’t work, check your Dodge Dart’s battery. Ensure the battery terminals are clean and securely connected. If you have jumper cables, try jump-starting your car. If it starts with a jump, your car battery may be the issue.
-
Rule Out Interference: Move your car to a different location, away from potential sources of strong radio interference (like radio towers or large electrical installations), and try starting it again.
-
Consult Your Owner’s Manual: Your Dodge Dart owner’s manual is a valuable resource. It may contain specific troubleshooting steps for key fob issues and emergency starting procedures for your particular model and year.
When to Seek Professional Help
If you’ve tried these troubleshooting steps and your Dodge Dart still won’t start, it’s time to consult a professional. A certified mechanic or your Dodge dealership’s service department can diagnose more complex issues, such as problems with the vehicle’s receiver module, immobilizer system, or other electrical faults.
Conclusion
While keyless entry and ignition systems offer convenience, they can sometimes present starting challenges. By understanding the potential causes of key fob-related starting problems and following these troubleshooting steps, you can often resolve the issue yourself. However, for persistent problems or if you are unsure, seeking professional help is always the best course of action to ensure your Dodge Dart is reliably back on the road. Remember, regular maintenance of your key fob, including battery replacement, can prevent many common starting issues and keep you enjoying the convenience of your Dodge Dart.
