First, locate the PATS module. In 2001‑2008 F‑Series trucks and 2002‑2007 Explorer SUVs, the module is mounted behind the steering column, beneath the dash, and is accessed by removing the lower steering wheel cover and the column cover plate. For 2009‑2014 models, the module moves to the passenger side footwell, secured by two Torx screws. Once exposed, verify the module’s serial number against the vehicle’s VIN; the last six digits of the VIN must match the module’s code for successful programming.
With the module identified, connect the Lock School Pro‑Key Programmer’s 6‑pin OBD‑II adapter to the vehicle’s OBD port. Power the programmer and select “Ford PATS” from the main menu. The software will read the module’s firmware version; ensure it is at least version 2.5.0, otherwise update the firmware using the built‑in “Module Update” routine before proceeding. After the module is recognized, insert the blank transponder key into the programmer’s key slot. The software will prompt you to “Add New Key.” Confirm, then the programmer will write the unique chip ID and the vehicle’s security seed to the key. Once the key is programmed, the system will automatically request a verification step; you must insert the newly programmed key into the ignition and turn it to the “ON” position for three seconds. The vehicle will flash the security light twice to confirm acceptance.
If the verification fails, the programmer will display an error code. Common issues include a mismatched VIN, a locked module (requires a master code), or a low‑battery condition in the vehicle (voltage below 12.0 V). To resolve a locked module, navigate to “Advanced → Module Reset” and input the master reset code supplied in the Lock School resource pack. After resetting, repeat the add and verify steps. Once the key passes verification, select “Lock Programming” to prevent any further keys from being added without authorization. The system will store the new key’s ID in the module’s internal database, and the programmer will generate a PDF receipt with the key’s serial number and programming timestamp for your records.
For bulk programming, use the “Export/Import” feature. Export the current key list to a CSV file, add new key IDs, then import the file back into the programmer. This method speeds up programming for fleet vehicles, reducing the per‑key time from 3 minutes to under 1 minute. Always run a final verification on a random sample of the newly programmed keys to ensure data integrity.
