    Step-by-step on-board programming

    The 2019 International LT does not support on-board programming for its key fobs. The keyless entry system for this vehicle is integrated into the Body Control Module (BCM) and requires specialized diagnostic equipment to program new or replacement key fobs. This procedure must be performed by a dealership or a certified automotive locksmith.

    Attempting to program the key fob yourself without the proper tools can result in the vehicle's security system becoming inoperable, potentially leaving you stranded or requiring costly repairs.

    Battery replacement

    Replacing the battery in your 2019 International LT remote key head is a straightforward process:

    1. Locate the small release button or notch on the side or bottom of the key fob and press it to release the mechanical key blade from the fob.
    2. With the key blade removed, you should see a seam on the side of the key fob. Carefully pry open the two halves of the fob using a small flathead screwdriver or a plastic trim tool.
    3. Inside, you will see the circular battery. Note its orientation (positive side up or down) before removing it.
    4. Gently remove the old CR2032 battery.
    5. Insert the new CR2032 battery, ensuring it is oriented correctly.
    6. Snap the two halves of the key fob back together until they click securely.
    7. Reinsert the mechanical key blade.

    Where to buy a replacement fob

    When considering a replacement key fob for your 2019 International LT, you have a few options, each with pros and cons:

    • Dealership:

      • Pros: Guaranteed genuine parts, factory-trained technicians, typically comes with a warranty.
      • Cons: Most expensive option, sometimes requires an appointment.
      • Ballpark Price: Expect to pay $250 - $400 or more for parts and programming.
    • Automotive Locksmith:

      • Pros: Often more affordable than a dealership, can provide mobile service, experienced with various makes and models.
      • Cons: Quality of aftermarket fobs can vary, ensure the locksmith has the necessary programming equipment for commercial vehicles.
      • Ballpark Price: $150 - $300, depending on the locksmith and the type of fob.
    • Amazon/Online Retailers:

      • Pros: Lowest upfront cost for the physical fob.
      • Cons: You still need to find a locksmith or dealer to cut the key blade and program the fob, potential for receiving incompatible or low-quality aftermarket fobs, no programming instructions provided for your specific vehicle.
      • Ballpark Price: $30 - $80 for the remote itself, plus programming and cutting costs from a locksmith or dealer (adding another $100 - $200 typically).

    If on-board programming isn't supported

    As established, the 2019 International LT requires specialized equipment for key fob programming. This means you will need to budget for professional services from a dealership or an automotive locksmith. Key fob programming for commercial vehicles often involves linking the new fob to the vehicle's Body Control Module (BCM) and ensuring the immobilizer transponder chip within the key head is correctly recognized by the vehicle's security system.

    The immobilizer transponder is a critical security feature that prevents the engine from starting if an unprogrammed or incorrect key is used. Even if you purchase an uncut, unprogrammed key fob online, it will still need to be properly programmed and the mechanical key blade cut to your vehicle's ignition and door locks to be fully functional.

    Cost Expectations: The total cost will largely depend on whether you go to a dealer or a locksmith, and what specific services are required (e.g., just programming a fob, or also cutting a new key blade). Always get a quote before proceeding.
