2017 Kenworth T680 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2017 Kenworth T680 does not support on-board key fob programming by the owner. Programming of new key fobs for your T680 requires specialized diagnostic equipment and software typically found at a Kenworth dealer or a professional automotive locksmith with heavy-duty truck capabilities. This is due to the advanced security systems integrated into modern commercial vehicles like the T680, which are designed to prevent theft and unauthorized access.

Battery replacement

Replacing the battery in your 2017 Kenworth T680 key fob is a straightforward process:

1. Locate the small notch or slot on the side of the key fob case. This is usually where the two halves of the fob meet.
2. Carefully 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 use excessive force, as this can damage the casing.
4. Once the case is open, you will see the circuit board and the battery. Note the orientation of the old battery (which side is facing up/down).
5. Carefully remove the old CR2032 battery. You might need the screwdriver to gently pry it out.
6. Insert the new CR2032 battery, ensuring it is oriented correctly (positive (+) side usually facing up).
7. Align the two halves of the key fob case and press them firmly together until they snap back into place.
8. Test the key fob to ensure it is functioning correctly.

Where to buy a replacement fob

When considering a replacement key fob for your Kenworth T680, you have several options, each with its own pros and cons:

• Kenworth Dealership:

  • Pros: Guaranteed genuine OEM part, expert programming by factory-trained technicians, typically comes with a warranty.
  • Cons: Most expensive option. Expect to pay anywhere from $250 to $500 or more for the fob and programming.

• Professional Automotive Locksmith:

  • Pros: Often more affordable than a dealership, can provide OEM or high-quality aftermarket fobs, offers mobile service, and can program the fob on-site. Locksmiths specializing in heavy-duty trucks will have the necessary equipment.
  • Cons: Prices can vary, ensure the locksmith has experience with Kenworth trucks. Ballpark cost usually ranges from $150 to $350.

• Online Retailers (e.g., Amazon, eBay):

  • Pros: Potentially the cheapest option for the fob itself. Many aftermarket options are available.
  • Cons: You're only buying the physical fob; you'll still need to pay for programming separately. Risk of buying a non-compatible or low-quality aftermarket fob. Beware of listings claiming "DIY programmable" for this vehicle, as it is incorrect. The cost of the fob alone might be $50 to $150, but remember to factor in programming costs from a dealer or locksmith.

If on-board programming isn't supported

As established, on-board programming is not an option for your 2017 Kenworth T680. This means you will need to rely on a professional service to get your new key fob programmed.

• Cost Expectations: As mentioned above, expect to pay anywhere from $150 to $500+ for a new key fob and programming, depending on whether you go through a locksmith or a dealership. Always get a quote beforehand.

• Immobilizer Transponder: The key fob for your Kenworth T680 likely contains an immobilizer transponder chip. This chip communicates with the truck's engine control unit (ECU) and must be correctly programmed to allow the vehicle to start. Simply having the remote functions working (lock/unlock) does not mean the truck will start if the transponder isn't programmed correctly. This is part of the specialized programming a dealer or qualified locksmith performs.
