2013-2016 Dodge Dart Anti-Theft Module (RF Hub): No-Start Diagnosis and Replacement Guide

Understanding the Dodge Dart Anti-Theft Module (RF Hub)

The Anti-Theft Module, or RF Hub, is a small but critical electronic box that manages your vehicle's security and keyless entry system. It's responsible for receiving signals from your key fobs for locking/unlocking, the panic alarm, and most importantly, authorizing the ignition to start the engine. It also receives signals from the Tire Pressure Monitoring System (TPMS) sensors. When this module fails, your key is no longer recognized, and the car may not start, leaving you stranded. This failure can be sudden, with the key fob working one day and being completely unresponsive the next.

Symptoms of a Failing Anti-Theft Module

A failing RF Hub can cause a range of frustrating and intermittent issues. Here are the most common signs to watch for:

• No-Crank, No-Start: This is the most severe symptom. You press the start button, the instrument cluster may or may not light up, but the engine will not crank at all.
• "Key Fob Not Detected" Message: The instrument cluster displays a message indicating it cannot find the key, even when it's inside the vehicle.
• Flashing Red Security Light: A solid or flashing red dot (the security indicator) on the dashboard when you try to start the car is a classic sign of an immobilizer fault.
• Key Fob Inoperative: The lock, unlock, and panic buttons on all of your key fobs suddenly stop working, or their range becomes extremely short.
• Intermittent Starting: The car may start fine on some days but fail to start on others, pointing to an internal electronic failure within the module.
• Engine Starts and Stalls: This specific symptom often occurs after a module has been replaced but not correctly programmed. The engine fires for a couple of seconds and then shuts down due to a VIN mismatch between modules.
• Faulty Tire Pressure Sensors: Since the RF Hub also processes signals from the TPMS sensors, you may notice intermittent or constant TPMS warnings in conjunction with other symptoms.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While there are no specific recalls for the RF Hub module itself, Dodge has issued related bulletins and recalls for the 2013-2016 Dart.

• TSB S2008000113: This bulletin addresses an intermittent no-start condition where the vehicle requires multiple push-to-start attempts to fire up, a symptom directly related to potential RF Hub issues.
• Recall S10: This recall involves a software update for the Powertrain Control Module (PCM) on certain 2016 Dart models with the 2.0L engine and a manual transmission. It addresses a missing software layer that could lead to an uncommanded torque event. While not an RF Hub issue, it's a relevant software update for the specified vehicle configuration.
• Recalls V34 / A0C (Automatic Transmission Only): Numerous recalls have been issued for a faulty shifter cable bushing on automatic transmission Darts, which can cause a rollaway risk. This does not apply to vehicles with a manual transmission.

CRITICAL: Programming and Installation Requirements

This is not a plug-and-play part. A replacement Anti-Theft Module, whether new or used, must be electronically programmed to your vehicle's Vehicle Identification Number (VIN) to function. Failure to program the module will result in a no-start condition. The programming process involves initializing the new module and re-learning all of your existing key fobs to it.

Who Can Program the Module?

• Dodge/Chrysler Dealerships: They have the required wiTECH diagnostic software to perform the replacement and programming.
• Qualified Automotive Locksmiths: Many professional locksmiths have advanced diagnostic tools (like Autel or Launch) and the necessary security credentials (NASTF subscription) to program new and used modules. Always confirm they can program an RF Hub for a Dodge Dart before purchasing the part.
• Advanced DIY (Not Recommended): Tools like AlfaOBD, paired with an OBD-II adapter, can potentially perform the "RF Hub Replace" procedure. However, this requires obtaining your vehicle's 4-digit security PIN from the dealer and is a complex process with a high risk of error for inexperienced users.

Buying a Used Dodge Dart Anti-Theft Module

Purchasing a used OEM RF Hub is an excellent way to save money, as the electronic component itself is generally reliable. A used module, once programmed, functions identically to a new one.

1. Verify the Part Number: Match the part number on your original module exactly. The most current part number is 68164928AI, which replaces all previous versions (AA, AB, AC, etc.). If possible, purchase the latest version available.
2. Confirm Manual Transmission: Double-check that the part is from a vehicle with a manual transmission. A module from an automatic will not work.
3. Inspect for Damage: Physically inspect the used module for any signs of corrosion on the pins, cracks in the casing, or evidence of water intrusion. A video from a repair service shows that damage to the BCM can sometimes damage the RF Hub as well, so a clean history is important.
4. Ignore "Unlocked" Claims: Be wary of sellers claiming a module is "unlocked" or "plug-and-play." All immobilizer-related modules require vehicle-specific programming.
5. Secure a Programmer First: Before buying the part, have a plan for programming. Get a quote from a local dealership or locksmith and confirm they are willing and able to program a customer-supplied used part.

Replacement Cost Comparison

Prices can vary by location and supplier. The main cost driver, aside from the part itself, is the specialized labor for programming.
