2016 Kenworth T680 Key Fob Programming Guide

Quick Reference

Step-by-step On-Board Programming

Unfortunately, the 2016 Kenworth T680 key fob cannot be programmed using an on-board DIY procedure. These vehicles require specialized diagnostic equipment (a scan tool) and software, typically found at a Kenworth dealership or a qualified commercial locksmith specializing in heavy trucks. This is due to the advanced security systems integrated into commercial vehicles to prevent theft.

Battery Replacement

1. Locate the battery compartment: The battery compartment is usually on the back of the fob, often secured by a small screw or a clip.
2. Open the fob: Use a small screwdriver or coin to gently pry open the fob casing. Be careful not to damage the internal components.
3. Note battery orientation: Before removing the old battery, observe its orientation (which side is positive/negative).
4. Remove the old battery: Gently pry out the old CR2032 battery.
5. Insert the new battery: Place the new CR2032 battery into the compartment, ensuring it's oriented correctly.
6. Close the fob: Snap the two halves of the fob back together securely.
7. Test the fob: Check if the fob now operates normally.

Where to buy a replacement fob

• Kenworth Dealership:
  • Pros: Guaranteed genuine OEM part, often comes with programming included in the purchase price.
  • Cons: Can be the most expensive option, potentially costing $150-$300 or more for the fob and programming.
• Locksmith:
  • Pros: Often more affordable than a dealership, especially a commercial locksmith specializing in heavy trucks. They can typically supply aftermarket fobs and perform programming on-site.
  • Cons: Ensure the locksmith has the correct specialized equipment for Kenworth trucks. Prices can vary, from $100-$250 for the fob and programming.
• Online Retailers (e.g., Amazon, eBay):
  • Pros: Lowest upfront cost for the fob itself, often $20-$80. You can choose between OEM and aftermarket options.
  • Cons: You will still need to pay for programming separately, which can be difficult to find if you don't have a local commercial locksmith. Be wary of counterfeit or incompatible fobs.

If on-board programming isn't supported

As mentioned, the 2016 Kenworth T680 requires professional programming. Expect to pay for both the replacement key fob and the programming service. The total cost will depend on where you purchase the fob and who performs the programming.

Kenworth T680 trucks utilize an immobilizer system to prevent unauthorized starting. The key fob's remote functions (lock/unlock) are separate from the transponder chip required to start the vehicle. While the fob itself doesn't have an integrated key blade, the truck's ignition key often contains a transponder chip that must be programmed to the truck's immobilizer system. If you're dealing with a new ignition key, this will also require specialized tools for programming.
