2024-2026 Jeep Wrangler/Gladiator Keyfob Not Detected TSB

Owners of 2024-2026 Jeep Wrangler and Gladiator vehicles may encounter issues with their key fobs, including problems with remote keyless entry, passive entry, or remote start functionality. In some cases, the vehicle's instrument cluster may display the message "Keyfob Not Detected". This manufacturer communication, identified as Case Number S2608000004, provides guidance for technicians to diagnose these specific key fob-related symptoms.

This bulletin, released in March 2026, aims to help technicians accurately identify the cause of these key fob malfunctions, ensuring proper diagnosis and repair.

Symptoms of a Malfunctioning Key Fob

If you own a 2024-2026 Jeep Wrangler or Gladiator, you might experience one or more of the following issues related to your key fob:

• Remote Keyless Entry is inoperative.
• Passive Entry system is not working.
• Remote Start feature is inoperative.
• A cluster message stating, "Keyfob Not Detected" appears on your dashboard.

These symptoms collectively indicate a potential problem with the key fob's communication with the vehicle or its internal components.

Diagnostic Procedure for Key Fob Issues

When a customer reports any of the symptoms listed above, technicians are instructed to first collect all available key fobs that are programmed to the vehicle. The diagnostic process then involves specialized tools to pinpoint the exact cause of the malfunction.

ATEQ Tool Usage

Technicians will use an ATEQ tool, specifically the Mopar 2046301080 TPM-RKE Analyzer, to perform two key diagnostic checks:

1. Fobik Signal Strength: The ATEQ tool can test the fobik signal strength. This helps identify if a low battery in the key fob is contributing to the problem. A weak signal can prevent the vehicle from properly detecting the key fob.
2. Fob ID Verification: The ATEQ tool's Fob ID feature allows technicians to verify if the FOBIK IDs from the key fobs match the programmed key fob data stored within the vehicle's modules. This step is crucial to confirm that the key fobs are correctly recognized by the vehicle's system.

wiTECH Scan Tool Feature

In addition to the ATEQ tool, the wiTECH scan tool provides a specific feature to test for programmed keys. This feature, found under the "Misc Functions" tab for the Radio Frequency Hub (RFH), is called "Key FOB Identification". This procedure helps determine whether a key fob is currently programmed to the vehicle, allowing technicians to confirm programming status before considering key fob replacement.

By following these diagnostic steps, technicians can systematically identify whether the issue stems from a weak key fob battery, incorrect key fob identification, or a programming discrepancy, helping to resolve the "Keyfob Not Detected" issue.

Important Considerations for Owners
