2024 Freightliner M2 106 — Key Fob Programming

Quick reference

Step-by-step on-board programming

The 2024 Freightliner M2 106 does not have an on-board programming procedure for key fobs. Programming a new key fob requires a diagnostic scan tool that can communicate with the vehicle's computer system. This is a job for a Freightliner dealer or a qualified locksmith with the appropriate equipment.

The reason for this is that the key fob is part of the vehicle's security system. The programming process involves pairing the unique code of the new fob with the vehicle's immobilizer. This prevents unauthorized fobs from starting the engine. A scan tool is needed to access the vehicle's computer and authorize the new fob.

Battery replacement

Replacing the battery in your 2024 Freightliner M2 106 key fob is a simple process you can do yourself.

1. Locate the seam: Look for a small seam along the edge of the key fob. This is where the two halves of the plastic casing are joined.
2. Pry open the case: Insert a small flathead screwdriver or a coin into the seam and gently twist to pry the case open. Be careful not to damage the plastic.
3. Remove the old battery: The battery will be a small, round CR2032 coin cell battery. Note the orientation of the battery (positive and negative sides) before removing it.
4. Insert the new battery: Place the new CR2032 battery into the fob, making sure it is oriented the same way as the old one.
5. Snap the case together: Align the two halves of the key fob and snap them back together until you hear a click.

Where to buy a replacement fob

• Freightliner Dealer: This is the most expensive option, but you are guaranteed to get a genuine OEM key fob that is compatible with your vehicle. Expect to pay in the range of $150 - $250 for the fob itself, plus an additional hour of labor for programming.
• Locksmith: A qualified automotive locksmith can often source OEM or high-quality aftermarket key fobs for a lower price than the dealer. They will also have the necessary equipment to program the fob to your truck. This is a convenient option as many locksmiths are mobile and can come to you.
• Amazon/Online Retailers: You can find a wide variety of aftermarket key fobs on Amazon and other online retailers. While this is the cheapest option, there is a risk of purchasing a low-quality or incompatible fob. Be sure to match the FCC ID and part number to your original fob. Keep in mind that you will still need to have the fob programmed by a dealer or locksmith.

If on-board programming isn't supported

As mentioned, the 2024 Freightliner M2 106 requires a diagnostic scan tool for key fob programming. This is because the key fob contains a transponder chip that is part of the vehicle's immobilizer system. The transponder chip must be programmed to the vehicle's computer in order for the engine to start.

When you purchase a new key fob, it is essentially a blank slate. The programming process involves a technician using a scan tool to communicate with the vehicle's Body Control Module (BCM). The scan tool tells the BCM to enter "learn mode," which allows it to accept the unique code from the new key fob. Once the code is learned, the new fob will be able to lock and unlock the doors, as well as start the engine.

The cost for this service can vary depending on the dealer or locksmith. Expect to pay for one hour of labor, which can range from $80 to $150.
