2014 Kenworth W900 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2014 Kenworth W900 does not support DIY on-board programming for its key fob remotes. The key fob contains a sophisticated immobilizer transponder chip, which communicates with the truck's engine control unit (ECU). Programming a new key fob, or even replacing an existing one, requires specialized diagnostic equipment to correctly code the transponder to the vehicle's immobilizer system. This is a security measure designed to prevent unauthorized starts.

Therefore, to program a new key fob for your 2014 Kenworth W900, you will need to visit a Kenworth dealership or consult with a professional automotive locksmith who has the necessary diagnostic tools and software for heavy-duty trucks.

Battery replacement

1. Locate the small notch or slot on the side of the key fob casing. This is typically 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 key fob apart.
4. Once open, locate the CR2032 coin cell battery. Note its orientation (which side is positive facing up).
5. Remove the old battery. You may need to gently pry it out with a small tool.
6. Insert the new CR2032 battery, ensuring the positive (+) side is facing the same direction as the old battery.
7. Align the two halves of the key fob casing and firmly press them back together until they click securely into place.

Where to buy a replacement fob

• Kenworth Dealership: This is often the most straightforward option, ensuring you receive a genuine OEM part that is guaranteed to work with your truck. However, it's typically the most expensive, with prices ranging from $150 to $300 for the fob itself, plus an additional $100 to $250 for programming and key cutting. The benefit is peace of mind and direct manufacturer support.
• Professional Locksmith: An automotive locksmith specializing in heavy-duty vehicles can often provide and program aftermarket key fobs (like the Strattec 5926639) or even OEM fobs at a more competitive price than a dealership. Expect to pay between $100 to $250 total for the fob, programming, and key cutting. This is often the best balance of cost and convenience.
• Online Retailers (e.g., Amazon, eBay): You can often find replacement key fobs, both OEM and aftermarket, at significantly lower prices online (e.g., $30 to $80 for the fob). However, remember that these will still require professional programming and key cutting. Be cautious of counterfeit products, and always verify the FCC ID and part number to ensure compatibility. This option usually ends up costing similar to a locksmith once programming and cutting services are factored in, but requires more effort on your part.

If on-board programming isn't supported

As established, on-board programming is not an option for the 2014 Kenworth W900. When dealing with a locksmith or dealership, be aware of the following:

• Cost Expectations: As noted above, expect to pay a combined total of $100 to $550+ depending on where you source the fob and who performs the work. Always get a quote beforehand.
• Immobilizer Transponder: The 2014 Kenworth W900 utilizes a sophisticated immobilizer system. This means the key fob contains a transponder chip that must be electronically paired with your truck's unique security code. Without proper programming, the truck will not start, even if the key physically turns the ignition. Both dealerships and qualified locksmiths have the necessary diagnostic equipment to perform this crucial programming.
