2020 Kenworth T680 Key Fob Programming Guide

Quick Reference

Step-by-step On-Board Programming

Unfortunately, the 2020 Kenworth T680 does not support DIY, on-board key fob programming. This is typical for heavy-duty trucks and commercial vehicles where security systems are more complex and integrated into the vehicle's diagnostic network. Programming a new key fob for your Kenworth T680 will require specialized diagnostic equipment and software, which is typically found at a Kenworth dealership or a qualified commercial vehicle locksmith.

The programming process involves connecting a scan tool to the truck's OBD-II port, accessing the security module, and following a specific procedure to add new key fob data to the truck's computer. Attempting to program these fobs without the correct tools can lead to issues with the vehicle's immobilizer system, potentially preventing the truck from starting.

Battery Replacement

Replacement of the key fob battery in your 2020 Kenworth T680 is a straightforward process:

1. Locate the seam: Look for a small seam around the edge of the key fob casing.
2. Pry open the case: Carefully insert a small, flat-head screwdriver or a coin into the seam and gently pry the two halves of the fob apart. Be careful not to damage the internal components.
3. Remove the old battery: Note the orientation of the battery (which side is facing up). Gently remove the old CR2032 coin cell battery.
4. Insert the new battery: Place a new CR2032 battery into the fob, ensuring it is oriented correctly.
5. Reassemble the fob: Carefully snap the two halves of the key fob back together until they are securely closed.
