2023-2025 Alfa Romeo, Dodge, Jeep Key Fob Programming Issue

Owners of certain 2023-2025 Alfa Romeo, Dodge, and Jeep vehicles may encounter difficulties when attempting to program a new or replacement key fob. This issue, detailed in Stellantis TSB S2308000041 Rev. B, specifically affects vehicles equipped with an Integrated Body Control Module (iBCM).

The core problem is that standard programming procedures for replacement key fobs will not work as expected. This technical service bulletin provides crucial information for dealers and owners regarding the proper method to obtain and program new key fobs for affected models, ensuring vehicle security and functionality.

Symptoms

The primary symptom an owner will notice is that a replacement key fob simply "Will Not Program On Vehicles Equipped With An iBCM." This means that even with the correct diagnostic tools, the vehicle's iBCM will not successfully pair with a new, unprogrammed key fob. This can leave owners unable to use their new fob for vehicle access or starting, leading to significant inconvenience.

This issue applies to 2023-2025 Alfa Romeo Tonale (GC), 2023-2025 Dodge Hornet (GG), and 2023-2025 Jeep Renegade (BV) models. If you are experiencing problems with your Alfa Romeo Tonale key fob programming, this bulletin provides the necessary guidance.

Important Warnings and Owner Advisories

Stellantis has issued specific warnings regarding this key fob programming issue:

• "Generic unprogrammed fobs in dealer inventory cannot be paired with the iBCM." This means that a standard, off-the-shelf key fob that has not been specifically prepared will not work with these vehicles. Dealers cannot simply program a generic fob they might have in stock.
• The Enable FOBIK pairing routine on iBCM-equipped vehicles is highly susceptible to Radio Frequency (RF) interference. To ensure successful pairing, it is critical to remove and distance all devices that could emit an RF signal from the vehicle. This includes aftermarket devices like GPS trackers and cell phone chargers, any other key fobs not currently being programmed, personal cell phones, and even the laptop used for the wiTECH diagnostic tool. Failure to do so can lead to repeated programming failures.

These warnings highlight the specialized nature of key fob replacement for these models and the importance of following precise procedures to avoid complications.

Diagnosis and Trigger Conditions

The issue arises when a technician attempts to program a replacement key fob to a vehicle equipped with an iBCM. While wiTECH updates have been implemented to facilitate the pairing process, the fundamental requirement is that the replacement fob must be preprogrammed by the supplier. This differs from older systems where a generic fob could be programmed on-site.

The iBCM's sensitivity to RF interference means that any nearby electronic device emitting radio signals can disrupt the programming process. The iBCM may mistakenly interpret these external signals as the fob being programmed, leading to a failed pairing attempt. This condition makes proper environmental control crucial during the programming procedure.

Repair Procedure Summary

The resolution for the Alfa Romeo Tonale key fob programming issue, and for the other affected models, involves a specific process:

1. Preprogramming Requirement: All replacement key fobs for 2023-2025 GC (Alfa Romeo Tonale), GG (Dodge Hornet), and BV (Jeep Renegades) vehicles must be preprogrammed by the supplier. This is a critical step that happens before the fob even reaches the dealership.
2. VIN-Specific Ordering: To ensure the correct preprogramming, replacement key fobs must be ordered using the vehicle's exact VIN (Vehicle Identification Number). This ensures the fob arrives already configured for that specific vehicle.
3. wiTECH Pairing: Once the preprogrammed, VIN-specific key fob is received, the wiTECH diagnostic system is used for the final pairing process. This step is similar to how earlier Promaster vehicles handled key programming, where the key arrived preprogrammed and wiTECH was used only for the final pairing.

This procedure ensures that the iBCM can properly recognize and integrate the new key fob into the vehicle's security system.

Owner Action

If you own a 2023-2025 Alfa Romeo Tonale, Dodge Hornet, or Jeep Renegade and require a replacement key fob, it is essential to visit an authorized dealership. Do not attempt to purchase and program generic key fobs, as they will not work with your iBCM-equipped vehicle. Inform the service department about the specific issue of your Alfa Romeo Tonale key fob programming, referencing TSB S2308000041 Rev. B if necessary. Ensure they order the replacement key fob using your vehicle's VIN to guarantee it arrives preprogrammed and ready for the final pairing process.
