2020 Volvo VNL Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2020 Volvo VNL does not support DIY on-board key fob programming. These modern heavy-duty trucks utilize a sophisticated electronic system that requires specialized diagnostic tools to program new key fobs. Attempting to program a key fob without the proper equipment can lead to issues with the vehicle's immobilizer system, potentially preventing the truck from starting.

Programming a new key fob for your 2020 Volvo VNL will require either a visit to a Volvo dealership or the services of a qualified automotive locksmith who possesses the necessary Volvo Tech Tool or equivalent diagnostic software.

Battery replacement

1. Locate the battery compartment: The battery compartment on your Volvo VNL key fob is typically located on the backside of the fob, often secured by a small screw or a snap-together housing.
2. Open the compartment: Use a small screwdriver or a pry tool to carefully open the battery compartment. If there's a screw, unscrew it first. For snap-together cases, gently pry along the seam.
3. Note the battery orientation: Before removing the old battery, observe its positive (+) and negative (-) terminals to ensure you install the new battery correctly.
4. Remove the old battery: Carefully remove the old CR2032 battery.
5. Insert the new battery: Place the new CR2032 battery into the compartment, making sure it's oriented correctly.
6. Close the compartment: Snap the cover back into place or replace the screw, securing the battery compartment.
7. Test the fob: Test the key fob to ensure it locks and unlocks the truck as expected.

Where to buy a replacement fob

• Volvo Dealership:

  • Pros: Guaranteed genuine OEM part, expert programming, and often comes with a warranty.
  • Cons: Most expensive option. Expect to pay anywhere from $200-$400 for the fob itself, plus an additional $100-$200 for programming and key cutting (if applicable). Total costs can easily reach $300-$600.

• Automotive Locksmith:

  • Pros: Often more affordable than a dealership, can provide on-site service (mobile locksmith), and typically have the necessary diagnostic tools. They may also offer both OEM and quality aftermarket options.
  • Cons: Ensure the locksmith specializes in heavy-duty trucks and has the correct equipment for Volvo VNLs. Prices can range from $150-$350 for the fob and programming, depending on the locksmith and whether they use an OEM or aftermarket part.

• Online Retailers (Amazon, eBay, etc.):

  • Pros: Potentially the cheapest option for the fob itself.
  • Cons: You must verify compatibility with your specific 2020 Volvo VNL. Many online fobs are advertised as compatible but may not work or may be of low quality. You'll still need to factor in the cost of programming from a dealership or locksmith, making the overall saving potentially minimal and the risk higher. We strongly recommend against purchasing key fobs for modern heavy-duty trucks from generic online retailers due to the complexity of the immobilizer system.

If on-board programming isn't supported

As established, on-board programming is not an option for your 2020 Volvo VNL. This means you will incur costs for professional programming. Be prepared for the following:

• Cost Expectations: As detailed above, expect to pay between $150 and $600 for a new key fob and programming, depending on your chosen vendor (dealership vs. locksmith) and whether you opt for an OEM or aftermarket part (if available from a locksmith).
• Immobilizer Transponder: The key fob for your Volvo VNL contains an immobilizer transponder chip, which is crucial for the vehicle's security system. This chip communicates with the truck's engine control unit (ECU) to allow the engine to start. When a new key fob is programmed, the transponder information is securely linked to the vehicle's immobilizer system. This is why specialized diagnostic tools are required for programming – to correctly register the new transponder with the vehicle's security system. DIY methods cannot bypass this security feature.
