2018 Freightliner M2 106 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2018 Freightliner M2 106 does not support DIY on-board key fob programming. These vehicles are equipped with sophisticated security systems that require specialized diagnostic equipment to program new key fobs. This process typically involves communicating with the vehicle's Body Control Module (BCM) or Central Gateway (CGW) to register the new fob's unique identification code.

Therefore, a professional locksmith or a Freightliner dealership will be required to program a new key fob for your M2 106.

Battery replacement

Replacing the battery in your 2018 Freightliner M2 106 key fob is a straightforward process.

1. Locate the small notch or slot on the side of the key fob casing. This is usually near the key ring loop.
2. Carefully insert a small, flat-head screwdriver or a coin into the notch.
3. Gently twist the screwdriver to pry open the two halves of the key fob casing.
4. Once opened, you will see the circuit board and the CR2032 coin cell battery.
5. Note the orientation of the old battery (usually positive side up) before removing it.
6. Carefully remove the old CR2032 battery.
7. Insert the new CR2032 battery with the positive (+) side facing the same direction as the old one.
8. Align the two halves of the key fob casing and press them firmly together until they snap shut.

Where to buy a replacement fob

• Freightliner Dealership: This is often the most reliable option for purchasing an OEM key fob. They will provide the correct part and can program it for you. Expect the highest cost, typically ranging from $200 to $400 or more, including programming.
• Professional Locksmith: Many automotive locksmiths can source and program aftermarket key fobs, and sometimes even OEM ones, at a more competitive price than the dealership. An aftermarket fob and programming could range from $150 to $300.
• Online Retailers (e.g., Amazon, eBay): You can often find blank key fobs online for a lower price (e.g., $30-$80). However, be extremely cautious. Ensure the FCC ID and part number (if listed) match your original fob. You'll still need to factor in the cost of cutting the key blade and professional programming, which can be an additional $100-$200.

Important Note on FCC ID and OEM Fob PN for Freightliner M2 106: Due to the nature of commercial truck components, specific FCC IDs and single OEM Part Numbers for key fobs can be difficult to pinpoint universally. Freightliner often uses various suppliers, and the exact fob may depend on the specific build and year of the truck. It's always best to consult your local Freightliner dealer with your VIN to confirm the correct part for your vehicle.

If on-board programming isn't supported

As mentioned, on-board programming is not available for the 2018 Freightliner M2 106. This means you will need to utilize the services of a professional.

• Cost Expectations: Expect to pay between $150 and $400 for a new key fob and programming. This cost can vary based on whether you purchase an OEM or aftermarket fob, and the labor rates of the locksmith or dealership.
• Immobilizer Transponder: The key fob for your Freightliner M2 106 contains a transponder chip that is part of the vehicle's immobilizer system. This chip sends a unique code to the vehicle's computer when you try to start the truck. If the code isn't recognized, the vehicle won't start, even if the key blade fits and turns. Programming involves matching this transponder chip to your truck's immobilizer system, which requires specialized equipment not available to the average vehicle owner. The integrated key blade will also need to be cut to match your truck's ignition and door locks.
