Adding a wired keyless entry keypad to your Ford Explorer offers convenient vehicle access. However, programming the keypad can sometimes present challenges. This article addresses a common issue encountered when programming a keypad (Part # LB5Z7820555E) on a 2025 Ford Explorer ST using FORScan and a vLinker FS USB OBDII adapter.
Keypad Programming Steps and Troubleshooting
The following steps were taken to program the Body Control Module (BdyCM) and Accessory Protocol Interface Module (APIM) using FORScan’s plain English menus:
-
Keypad Enabled in BdyCM: The keypad was successfully enabled in the BdyCM hardware settings.
-
Keypad Enabled in APIM: The keypad was successfully enabled in the APIM settings.
-
BdyCM LIN Calibration: A Local Interconnect Network (LIN) new module calibration was successfully performed on the BdyCM.
-
Factory Code Retrieval: The factory key code was successfully retrieved by cycling the ignition and swapping the two keys. The code displayed on the instrument panel. This code was further verified by successfully setting a personalized code through the vehicle’s settings menu.
-
Keypad Remains Unresponsive: Despite these successful steps, the keypad does not respond. Pressing 7/8 and 9/0 does not lock the vehicle, and neither the factory code nor the personal code unlocks the vehicle. The keypad illuminates when numbers are pressed, and the red LED indicator at the top lights up with each button press. Enabling “LIN Enabled” in the BdyCM also did not resolve the issue. Furthermore, all programmed addresses and values in the As-Built data were cross-referenced with the latest FORScan spreadsheet to ensure accuracy.
Potential Solutions and Further Investigation
Since the vehicle is a 2025 model, there might be additional programming requirements not covered in the current FORScan documentation. The 2025 Explorer Workshop Manual recommends using Ford Diagnostic and Repair System (FDRS) and running a LIN New Module Calibration after enabling the keypad. However, the FORScan spreadsheet only lists keypad options within the BdyCM and APIM modules.
Possible areas for further investigation include:
-
FDRS Calibration: Attempting the LIN New Module Calibration using FDRS, as recommended by the workshop manual, might be necessary. This could potentially address any model-specific programming differences.
-
FORScan Updates: Ensuring the latest version of FORScan and its associated spreadsheet are being used is crucial. New updates might include necessary features or fixes for 2025 models. While the 2.4.14 Beta version was used, checking for a stable release is recommended.
-
Dealer Consultation: If FORScan and FDRS solutions prove unsuccessful, consulting a Ford dealership might be necessary. They have access to proprietary diagnostic tools and the latest information on model-specific programming procedures.
Conclusion
While the initial FORScan programming steps appeared successful, the unresponsive keypad on the 2025 Ford Explorer ST suggests potential compatibility issues or missing programming steps. Exploring FDRS calibration, using the latest FORScan updates, and consulting a Ford dealership are recommended next steps to resolve the problem. Successfully integrating a keyless entry keypad significantly enhances vehicle accessibility and convenience.
