2016 Kenworth W900 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2016 Kenworth W900 does not support DIY on-board programming for key fobs. This means you will not be able to program a new key fob yourself simply by following a sequence of steps in the vehicle. The specialized software and equipment required are typically only found at a Kenworth dealership or a qualified automotive locksmith.

The vehicle's security system requires a diagnostic scan tool to access the body control module (BCM) and program new key fobs. This process links the unique identifier of your new fob to your truck's computer system, ensuring only authorized fobs can operate the vehicle.

Battery replacement

Replacing the battery in your Kenworth W900 key fob is a simple process:

1. Locate the small notch or slot on the side of the key fob casing.
2. Use a flathead screwdriver or a coin to carefully pry apart the two halves of the fob.
3. Gently remove the old CR2032 battery. Note the orientation of the positive (+) and negative (-) terminals.
4. Insert the new CR2032 battery, ensuring it's correctly oriented.
5. Snap the two halves of the key fob back together until you hear a click.

Where to buy a replacement fob

When it comes to replacing your Kenworth W900 key fob, you have a few options, each with its own pros and cons:

• Kenworth Dealership: This is the most reliable option for genuine OEM parts. You're guaranteed compatibility and often receive a warranty. However, it's typically the most expensive, with a new fob and programming costing anywhere from $250 to $400 or more, depending on labor rates and the specific fob type.

• Automotive Locksmith: A qualified automotive locksmith can often provide and program aftermarket or even OEM key fobs at a more competitive price than a dealership. They have the necessary diagnostic equipment and expertise to program the fob to your truck's immobilizer system. Costs can range from $150 to $300, often including the fob and programming.

• Online Retailers (e.g., Amazon, eBay): You can often find replacement key fobs (both OEM and aftermarket) for significantly less online, sometimes as low as $30 to $80. However, be extremely cautious about authenticity and compatibility. While you might save money on the fob itself, you'll still need to factor in the cost of professional programming, as DIY options are not available for your W900.

If on-board programming isn't supported

As established, on-board programming is not an option for the 2016 Kenworth W900. This means you'll need to rely on professional services to get a new key fob programmed.

• Cost Expectations: Expect to pay for both the key fob itself and the programming service. As mentioned above, a dealership will be the most expensive, followed by an automotive locksmith. If you purchase a fob online, remember to budget for the locksmith or dealer's programming fee.

• Immobilizer Transponder: The Kenworth W900 utilizes an immobilizer system as a security measure. This system requires that a transponder chip embedded in your key fob communicates a unique code to your truck's computer (the immobilizer) before the engine can start. When a new key fob is programmed, the immobilizer system learns the unique code of that new transponder, allowing it to disarm the immobilizer and enable the engine to start. Without proper programming, even a perfectly cut key will not start the truck.

• Key Cuts: If your Kenworth key fob includes an integrated metal key blade (common for primary keys), that blade will also need to be cut to match your truck's ignition and door locks. This is a separate service from programming the electronic functions of the fob and can usually be done by a locksmith or the dealership.
