2022-2025 Jeep/Ram RKE Functions Not Working TSB

Owners of 2022-2025 Jeep, Ram, and Dodge vehicles may experience problems with their Remote Keyless Entry (RKE) system, including situations where the RKE functions do not work, there is intermittent vehicle response, or the key is not programmed correctly. This can also affect the functionality of adding remote start. TSB S2408000015 provides technicians with a comprehensive diagnostic and repair procedure to address these concerns, ensuring proper operation of the RKE system.

This bulletin, released in April 2025, specifically targets issues reported by vehicle owners where the RKE buttons respond intermittently or not at all. For example, if your Jeep Wrangler RKE functions are unreliable, this TSB outlines the steps your technician should follow.

Symptoms

Vehicle owners may notice one or more of the following issues with their Remote Keyless Entry system:

• "Remote Keyless Entry (RKE) Functions Do Not Work"
• "Intermittent Vehicle Response When Using the RKE"
• "Key Not Programmed"
• Difficulties when "Adding Remote Start"

These symptoms often manifest as the vehicle failing to lock, unlock, or respond to other key fob commands consistently.

Fault Codes / DTCs

Technicians should first check for Diagnostic Trouble Codes (DTCs) related to the Passive Entry (PE) or remote start systems. The presence of these codes can help pinpoint antenna-related issues affecting key performance. The TSB lists the following specific DTCs:

Code	Description
B1A76-11	Remote Start Antenna Circuit-Circuit Short to Ground
B1A76-13	Remote Start Antenna Circuit-Circuit Open
B1A71-13	Passive Entry Antennas 1 Circuit Open
B1A72-13	Passive Entry Antennas 2 Circuit Open
B1A73-13	Passive Entry Antennas 3 Circuit Open
B1A74-13	Passive Entry Antennas 4 Circuit Open
B1A75-13	Passive Entry Antennas 5 Circuit Open

Diagnosis / Trigger Conditions

If no specific DTCs are present, or as part of a comprehensive diagnosis, technicians should follow these steps:

1. Key Fob Programming Verification: Use a scan tool to verify that the Radio Frequency Hub Module (RFHM) data shows both key fobs are correctly programmed for the vehicle. If a new OEM key fob is not listed, it should be properly paired.
2. Key Fob Inspection: For the problematic key fob, inspect it for case separation. Remove the coin battery and check for any signs of corrosion. If corrosion is found and the fob is inoperative, this condition is typically not covered under warranty.
3. Battery Voltage Test: Test the key fob's coin battery with a voltmeter. If the voltage is below 2.6V, the battery should be replaced.
4. RKE Signal Performance Test: Use an ATEQ VT56 tester to assess the key fob's remote signal strength. This test should be performed at various parked vehicle locations to evaluate distance range performance and ensure consistent RKE functionality.
5. Environmental Interference Check: Verify that there are no aftermarket LED light installations, either external or internal, that might be interfering with a consistent RKE signal. Also, confirm that the intermittent RKE operation is not specific to a single location, which could indicate external interference.
6. RFHM Programming Check: If the RFHM has been upgraded to include remote start functionality, ensure that the programming procedures outlined in the Service Library (SL) – 08 Electrical /8N – Power Systems / Power Locks / Transmitter, Integrated Key Fob / Standard Procedure have been correctly followed. Proper programming is essential for system operation and warranty coverage.

Important Warnings / What Owners Should Know

Owners should be aware of the following points regarding this technical service bulletin:

• This document does not authorize warranty repairs directly. The decision for appropriate action rests with the technician.
• If corrosion is found within the key fob and it is inoperative, this condition is generally not covered by warranty.
• If the key fob battery voltage is low (below 2.6V), replacing the battery is the recommended first step.
• Proper programming of the Radio Frequency Hub Module (RFHM) is crucial for the RKE system's operation and for any potential warranty claims.

Owner Action

If you are experiencing issues where your Jeep Wrangler RKE functions are not working, or if you encounter any of the symptoms described above with your 2022-2025 Jeep, Ram, or Dodge vehicle, it is recommended to schedule an appointment with an authorized dealership. Technicians will utilize TSB S2408000015 to diagnose the root cause, which may involve checking for specific DTCs, inspecting your key fob, or performing system programming updates.
