It’s frustrating when your key fob stops working, especially when you rely on it daily for your 2013 Dodge Dart. If you’re experiencing issues with your key fob not functioning, you’re not alone. This article will guide you through the likely causes and solutions, focusing on the common culprit: the Radio Frequency Hub Module (RFHM).
Based on factory service manual information, for a 2013 Dodge Dart Key Fob Not Working, the issue is likely not a simple programming problem, but rather a hardware malfunction. You might be tempted to think there’s a secret key fob programming procedure, but for the Dart, that’s generally not the fix. The most probable cause is a failing RFHM.
The RFHM is responsible for receiving signals from your key fob and controlling functions like locking, unlocking, and starting your vehicle. When it malfunctions, your key fob may become unresponsive.
Diagnosing the Issue: Is it Really the RFHM?
Before jumping to conclusions and assuming it’s the RFHM, consider a few basic checks:
- Key Fob Battery: This might seem obvious, but ensure you’ve replaced the battery in your key fob with a fresh one. A low battery is a common cause of key fob issues.
- Check the Second Key Fob: If you have a spare key fob, test if it works. If the second fob also fails, it strengthens the likelihood of an RFHM problem.
If you’ve ruled out the key fob battery and both fobs are unresponsive, the RFHM is indeed the prime suspect.
Replacing the RFHM: A Step-by-Step Guide (Based on Factory Service Manual)
Replacing the RFHM is not a simple DIY task and often requires specialized tools and access to manufacturer resources. However, understanding the process can be helpful. According to the factory service manual (FSM), here’s a breakdown of the RFHM replacement procedure:
-
Preparation: Connect a diagnostic scan tool to your Dodge Dart’s Data Link Connector (DLC).
-
Navigate to RF-Hub: Using the scan tool, navigate to the “RF-Hub (RFH)” section within the vehicle view.
-
RF-HUB Replace Routine: Select “RF-Hub” and initiate the “RF-HUB Replace” routine in the scan tool menu.
- DealerCONNECT Login and PIN: This step is crucial. The procedure requires logging into DealerCONNECT (the official FCA/Stellantis dealer network) and entering a PIN. This PIN is temporary, valid for only 12 hours, after which a new PIN must be obtained. This typically means you’ll need dealer involvement or a professional mechanic with access.
-
PROXI Configuration Alignment: After the RF-HUB Replace routine, select “Misc. Function” and perform the “PROXI Configuration Alignment” routine. This step ensures all vehicle modules are properly communicating after the RFHM replacement.
-
Prepare for FOBIK Programming: Place all key fobs (FOBIKs) used with your vehicle on the front seat, away from the center console area (to avoid antenna interference).
-
Program Ignition FOBIKs: Using the scan tool, select “Program ignition FOBIKs” from the Miscellaneous Functions menu and carefully follow the on-screen instructions.
- DealerCONNECT PIN Required Again: Similar to step 3, this key fob programming procedure will also require DealerCONNECT login and a temporary PIN.
- FOBIK Handling Note: When instructed to “Press the Unlock button” during programming, press it quickly once. Avoid holding the button down.
-
BCM Update: After programming all FOBIKs, turn the ignition to the “ON” position and use the scan tool to select “BCM” (Body Control Module).
-
Update Tire Pressure Values: Update the Front and Rear Axle Normal Tire Pressure Values within the BCM settings.
-
Program Tire Sensor IDs: Program the Tire Sensor IDs in the BCM.
-
Ignition Cycle: Turn the ignition to the “OFF” position, wait for 30 seconds, and then cycle the ignition back to the “ON/RUN” position.
-
Check for DTCs: Use the scan tool to check for any active RF-Hub Diagnostic Trouble Codes (DTCs). If any codes are present, refer to the relevant section of the service manual for further troubleshooting.
-
FOBIK Operation Check: Turn the ignition off and thoroughly test each key fob to ensure proper operation of all functions (locking, unlocking, remote start if equipped, etc.).
-
Final Installation: Complete the physical installation of the new RFHM, ensuring all connections are secure.
-
Body Verification Test: Perform the BODY VERIFICATION TEST as outlined in the service manual, typically within the BCM diagnostics section.
Alternative Solutions and DIY Options (Proceed with Caution)
While the factory procedure heavily relies on DealerCONNECT and professional tools, there might be alternative approaches for DIY enthusiasts, although success isn’t guaranteed and could have implications:
-
alfaOBD: The original article mentions alfaOBD, a third-party diagnostic software, and its potential use in RFHM replacement for some vehicles (specifically referencing RAM trucks). It might work for the Dodge Dart, but compatibility should be verified. Some users in online forums have reported success using alfaOBD and a four-digit PIN for RFHM replacement.
-
PIN Acquisition: To use alfaOBD (or even some professional scan tools outside of DealerCONNECT), you’ll likely need the four-digit PIN code for your vehicle. There are “PIN puller” apps and services mentioned online that may help retrieve this PIN without going to a dealer. However, the reliability and security of these methods can vary, so proceed with caution and research thoroughly.
Important Considerations:
- Complexity: RFHM replacement and programming are complex electronic procedures. Incorrect steps can lead to further issues or system malfunctions.
- Dealer Involvement: The factory recommended procedure strongly suggests dealer involvement due to the DealerCONNECT requirement and PIN access.
- Warranty: If your 2013 Dodge Dart is still under any form of warranty (unlikely for a 2013 model year but possible with extended warranties), unauthorized RFHM replacement might void the warranty.
Conclusion
If your 2013 Dodge Dart key fob is not working, don’t immediately assume it’s a simple fix. While battery replacement is the first step, a failing RFHM is a very likely cause. Replacing the RFHM requires specific procedures, diagnostic tools, and often access to DealerCONNECT. While DIY alternatives like alfaOBD might exist, they come with risks and require technical expertise.
For most owners, especially those without extensive automotive repair experience and diagnostic tools, seeking professional help from a qualified mechanic or Dodge dealership is the recommended course of action to properly diagnose and resolve a 2013 Dodge Dart key fob issue related to a potentially faulty RFHM.
