2018 Volvo VNL — Key Fob Programming Guide

Quick reference

Item	Detail
FCC ID	Not standardized/published for all VINs. Check the label on your existing remote (back cover or inside the shell) to confirm.
OEM Fob PN	Varies by VIN and option package. Have a Volvo dealer run your VIN to identify the correct part number printed on/inside the fob.
Aftermarket Options	Available, but must exactly match your FCC ID, frequency, and Volvo part number. Avoid “universal” remotes.
Battery Type	Coin cell; commonly CR-series (e.g., CR2032). Open your fob and confirm the stamp before purchase.
Programmable On-Board?	No. 2018 VNL requires a compatible scan tool (Volvo PTT/diagnostic) or a heavy-truck locksmith tool to add/rematch remotes/keys.
Cuts Required?	Yes. If replacing the key blade or a keyed remote, it must be cut to your VIN/key code and paired to the immobilizer.

Step-by-step on-board programming

DIY, in-cab programming is not supported on the 2018 Volvo VNL. Remote/key data is stored in the truck’s body/central electronics and immobilizer modules and requires a scan tool session (Volvo Premium Tech Tool or an advanced locksmith device) to add, erase, or rematch keys and remotes. This authentication process prevents theft and cannot be performed by cycling the ignition or door locks.

If you’re replacing or adding a fob/key, follow these steps to get it programmed correctly:

1. Gather your information

• Proof of ownership (registration/title and photo ID)
• The truck’s VIN and current mileage
• Any existing working key/fob you still have

2. Choose who will program it

• Volvo dealer: Has factory access and can order the exact part by VIN.
• Mobile/commercial locksmith: Often faster/on-site and can source matching aftermarket or OEM fobs.

3. Source a compatible fob/key

• Match the FCC ID and Volvo part number to your VIN. If you don’t have a fob to read, the dealer or a qualified locksmith can look it up by VIN and equipment.

4. Key cutting (if applicable)

• Provide your key code (from Volvo/dealer) or have the locksmith decode an existing key to cut the new blade accurately.

5. Programming session

• Technician connects a scan tool, verifies security access, and programs the new fob/key into the vehicle’s memory. Expect all existing keys/fobs to be present; some procedures erase and re-add all at once.

6. Test everything

• Verify lock/unlock, panic (if equipped), remote start/aux (if equipped), and that the engine starts and runs for more than 10 seconds with the new key.

Battery replacement

Because the exact remote variant can differ by VIN and market, open your remote and confirm the battery type before purchase.

1. Open the fob

• Remove the key blade (if present) and use a small flat tool in the seam to gently pry the case apart. Work evenly to avoid cracking tabs.

2. Identify and replace the coin cell

• Note the battery size stamped on the cell (commonly a CR-series, such as CR2032) and the polarity orientation (+ facing up on most designs). Replace with a quality brand cell.

3. Reassemble and test

• Snap the shell together, reinstall the key blade, and test buttons near the truck. If range is weak, recheck that the cell is fresh and seated properly.

Where to buy a replacement fob

• Volvo dealer

  • Pros: Guaranteed VIN-correct part, latest software bulletins, clean programming history.
  • Cons: Usually the highest price; shop scheduling may delay service.
  • Typical cost: $250–500+ parts and programming, depending on configuration.

• Commercial/mobile locksmith (heavy-truck capable)

  • Pros: On-site service, competitive pricing, can cut keys and program same visit; may offer OEM or high-quality aftermarket.
  • Cons: Quality varies—verify they can match FCC ID/PN and have heavy-truck tools.
  • Typical cost: $180–400 total, depending on part source and travel.

• Online (Amazon/eBay/parts retailers)

  • Pros: Lower part price, wide selection.
  • Cons: High risk of mismatch or low-quality clones; you still need professional programming and cutting.
  • Typical cost: $40–150 for the fob alone, plus programming/cutting ($120–250).

If on-board programming isn't supported

Expect a professional programming visit. Here’s what that entails and what to budget for:

• Security/immobilizer: The 2018 VNL uses a truck-grade immobilizer. New keys/remotes must be registered in the vehicle’s modules with a scan tool and security authorization. The transponder chip type can vary by build; your provider will identify it by VIN or by reading your working key.
• All keys lost: Plan for higher cost. The truck may require immobilizer reset and re-learning from scratch, and key code retrieval for cutting.
• Estimated totals: $200–600 depending on how many keys/fobs you add, whether you provide the part, and whether an immobilizer reset is needed.

Tips

• Always bring all existing keys/fobs to the appointment.
• Verify return policy when buying online in case the FCC ID/PN doesn’t match.
• Keep a spare, programmed key/fob to avoid costly “all keys lost” scenarios.
