2016 Volvo VNL Key Fob Programming Guide

As an ASE-certified electrical technician and locksmith, I often get questions from owner-operators and fleet managers about replacing keys and remotes for heavy-duty trucks. The 2016 Volvo VNL is a workhorse, but losing a key fob can cause significant downtime. Unlike older mechanical trucks, the 2016 VNL utilizes advanced electronics for both remote keyless entry (RKE) and anti-theft immobilization.

Here is everything you need to know about replacing, programming, and maintaining the key fob for a 2016 Volvo VNL.

Quick reference

Step-by-step on-board programming

If you are hoping to jump in your truck, cycle the key a few times, and pair a new remote, I have some bad news: the 2016 Volvo VNL does not support DIY on-board programming.

Modern Volvo heavy-duty trucks integrate the keyless entry system with the truck's central Body Builder Module (BBM) and immobilizer system. To program a new key or remote to the truck, you must establish a secure connection using Volvo's Premium Tech Tool (PTT) diagnostic software or a high-end aftermarket heavy-duty scan tool (like an Autel MaxiSys CV or TEXA).

Because of this, the programming procedure is strictly diagnostic:

1. Connect the heavy-duty scan tool to the truck's 9-pin diagnostic port.
2. Boot up Volvo PTT or your compatible HD diagnostic software.
3. Navigate to the Keyless Entry / Immobilizer programming menu.
4. Enter the required security parameters or PIN (if prompted).
5. Follow the on-screen prompts to clear lost remotes and marry the new fob's signal to the truck's receiver.

Unless you run a fleet shop equipped with thousands of dollars in HD diagnostic equipment, you will need to hire a professional to pair your new remote.

Battery replacement

If your current remote is just acting up or suffering from poor range, you likely just need a new battery. The procedure takes less than two minutes:

1. Locate the small seam running along the side of your Volvo VNL key fob.
2. Insert a small flathead screwdriver or a coin into the notch at the bottom of the fob.
3. Gently pry the two halves of the plastic casing apart.
4. Remove the old battery, noting the orientation.
5. Insert a fresh CR2032 battery with the positive (+) side facing up.
6. Snap the two halves of the plastic shell back together firmly until you hear a click.

Where to buy a replacement fob

When securing a replacement key fob for your VNL, you have three main avenues:

• Volvo Commercial Dealer: This is the most reliable option. A dealer will supply the OEM fob (PN 85117961) and has the proprietary Tech Tool software to program it perfectly. Pros: Guaranteed to work. Cons: Most expensive route (often $200–$350+ for parts and labor) and requires towing or driving the rig to the dealership.
• Heavy-Duty Locksmith: A specialized commercial auto locksmith can come directly to your truck stop, yard, or breakdown location. Pros: Mobile service saves downtime; slightly cheaper than the dealer. Cons: You must ensure they have HD scanner capabilities, as not all standard automotive locksmiths do. Expect to pay $150–$250.
• Amazon / Online Retailers: You can buy aftermarket replacement fobs (like Dorman) online. Pros: Highly cost-effective for the part itself ($30–$60). Cons: You still have to pay a locksmith or dealer to cut the key and program the remote, and some shops refuse to program outside parts.

If on-board programming isn't supported

As mentioned, DIY programming is simply not an option for this model year. Beyond just unlocking the doors, your 2016 VNL key likely houses a transponder chip that communicates with the truck's immobilizer. If the key is not programmed to the truck's Engine Control Unit (ECU), the truck will crank but will not start.

When budgeting for a replacement, remember that you are paying for both the mechanical cutting of the heavy-duty key blade and the digital programming of the transponder/remote. Expect the total cost to range between $150 and $350 depending on your location and whether you use a mobile service or a dealership.
