2015 Kenworth W900 – Key Fob Programming

Quick Reference

Step-by-Step On-Board Programming

Unfortunately, the 2015 Kenworth W900 does not support DIY on-board programming for its key fobs. The sophisticated security system in these heavy-duty trucks requires specialized diagnostic equipment to program new key fobs. This means you'll need to visit a Kenworth dealer or a qualified automotive locksmith who has the necessary scan tools and software.

The programming procedure typically involves:

1. Connecting a diagnostic scan tool to the vehicle's OBD-II port.
2. Accessing the body control module (BCM) or relevant security system menu.
3. Following on-screen prompts to add new key fobs or re-program existing ones.
4. This process often requires entering a security code or PIN, which only dealers or authorized locksmiths can obtain.

Attempting to program these fobs without the correct tools can lead to issues with the vehicle's security system and potentially render the fob unusable.

Battery Replacement

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

1. Locate the small notch or opening on the side or bottom of the key fob casing. This is usually where the two halves of the fob meet.
2. Insert a small flat-head screwdriver or a coin into the notch.
3. Gently twist the screwdriver or coin to pry the two halves of the fob apart. Be careful not to damage the plastic casing or the internal components.
4. Once opened, you will see the circuit board and the coin-cell battery. Note the orientation of the battery (usually positive (+) side up).
5. Carefully remove the old CR2032 battery. You might need to use the screwdriver to gently lift it out.
6. Insert the new CR2032 battery, ensuring it is correctly oriented with the positive (+) side facing up.
7. Align the two halves of the key fob casing and press them firmly together until they snap shut.
8. Test the fob's functionality (lock, unlock) to ensure the new battery is working correctly.
