Having your Dodge Dart key fob stuck in the ignition can be a frustrating and inconvenient experience. While modern keyless ignition systems are designed for ease of use, they can sometimes encounter glitches. Understanding the potential causes and solutions can help you address this issue effectively. This guide will walk you through possible reasons why your Dodge Dart key fob might be stuck and outline steps, including Radio Frequency Hub Module (RFHM) verification, that might be necessary to resolve the problem.
Understanding the RF Hub and Key Fob System
The Radio Frequency Hub Module (RFHM) is a critical component in your Dodge Dart’s security and keyless entry system. It communicates with your key fob to manage various functions, including ignition, remote start, and passive entry. When you insert your key fob into the ignition, the RFHM verifies the key’s signal and allows the car to start. Issues within this system can sometimes lead to a key fob becoming stuck in the ignition.
Diagnosing a Stuck Key Fob in Your Dodge Dart
Several factors can contribute to a Dodge Dart key fob getting stuck in the ignition. These can range from simple mechanical issues to more complex electronic problems:
- Mechanical Obstruction: Sometimes, debris or wear and tear within the ignition cylinder can physically prevent the key fob from releasing.
- Steering Column Lock: If the steering wheel is locked in a specific position with pressure on the ignition, it might prevent the key fob from turning to the ‘off’ position and releasing.
- Low Key Fob Battery: While less likely to cause a stuck key, a critically low battery in your key fob could lead to communication issues with the RFHM, potentially causing unexpected behavior.
- RFHM or Electronic System Glitch: Problems within the RFHM or related electronic control modules can disrupt the normal key release mechanism. This could be due to software glitches, module malfunctions, or issues following component replacement.
RF Hub Verification Test and Key Fob Programming
In some cases, especially after replacing the ignition switch or RFHM, a verification test and key fob reprogramming might be necessary. The following steps outline a general procedure, often involving a diagnostic scan tool like alfaOBD, to ensure the RFHM and key fobs are correctly synchronized with your Dodge Dart:
Note: These steps are technical and may require specialized tools and knowledge. If you are not comfortable performing these procedures, it is recommended to consult a qualified automotive technician.
-
Preparation: Ensure all components and connectors are properly reconnected. You may need your vehicle’s Personal Identification Number (PIN), which can be found on your original vehicle invoice or obtained from your dealer.
-
Access RFHM with Scan Tool: Turn the ignition to the ‘on’ position (without starting the engine). Using a diagnostic scan tool, select the RFHM module. If a “PROXI Configuration issue” message appears, follow the scan tool’s prompts to continue.
-
Key Fob Programming (if necessary): If the RFHM was replaced or you are using new key fobs, you will need to program all key fobs intended for use with the vehicle. Navigate to “Misc. Functions” in the scan tool menu, select “Program Ignition FOBIKs,” and follow the on-screen instructions. Ensure all key fobs are placed on the front seat near the console during programming.
-
RFHM Replacement Procedure (if applicable): If the RFHM module was replaced, use the scan tool to select “RFHM,” then “Misc. Functions,” and finally “RFHM Replace.” Follow the instructions provided by the scan tool to complete the replacement procedure.
-
Post-Procedure Steps:
- Turn the ignition off, leaving the key in the ‘on’ position as instructed by the scan tool.
- If the RFHM was replaced, update the Front and Rear Axle Normal Tire Pressure Values and program the Tire Sensor IDs using the scan tool.
- Erase all RFHM Diagnostic Trouble Codes (DTCs) with the scan tool.
- Test all RFHM functions, including passive entry, remote start, and ignition positions, to ensure they are working correctly.
- Wait for four minutes and then read the RFHM DTCs again using the scan tool to check for any new error codes.
-
Verification: Check for any RFHM DTCs or malfunctioning RFHM functions. If issues persist, further diagnosis and repair are required, potentially involving professional diagnostic procedures. If no DTCs are present and all functions operate correctly, the repair is complete.
When to Seek Professional Help
While some minor issues, like a steering column lock or needing to reprogram a key fob, might be resolvable with DIY effort, a stuck key fob can sometimes indicate a more serious underlying problem within your Dodge Dart’s electronic systems. If you are unable to remove your key fob, or if the issue persists after attempting basic troubleshooting, it is best to consult a qualified mechanic or your Dodge dealership. They have the expertise and diagnostic tools to accurately pinpoint the cause of the problem and perform the necessary repairs, including complex RFHM or electronic module diagnostics and reprogramming.
