2017 Peterbilt 389 Key Fob Programming

Quick Reference

Step-by-Step On-Board Programming

The 2017 Peterbilt 389 does not support DIY, on-board key fob programming. The remote entry system for this vehicle requires specialized diagnostic equipment to program new or replacement remotes. This process typically involves accessing the vehicle's body control module (BCM) or a dedicated security module with a scan tool that can communicate with Peterbilt's proprietary systems.

Attempting to program these remotes yourself without the correct tools can lead to issues with the vehicle's security system or render the remote inoperable. It is best to have this procedure performed by a qualified professional.

Battery Replacement

The remote fob for your 2017 Peterbilt 389 uses a CR2032 coin cell battery. Replacing the battery is a straightforward process:

1. Locate the small notch or slot on the side of the key fob casing.
2. Carefully insert a small flathead screwdriver or a coin into the slot.
3. Gently twist the screwdriver or coin to pry open the two halves of the fob casing.
4. Note the orientation of the old battery (usually positive (+) side up).
5. Remove the old CR2032 battery.
6. Insert the new CR2032 battery with the positive (+) side facing the same direction as the old one.
7. Align the two halves of the key fob casing and press them firmly together until they snap shut.

Where to Buy a Replacement Fob

Finding a replacement remote for your Peterbilt can be a bit different than for a passenger car. Here's a breakdown of your options:

• Peterbilt Dealer:

  • Pros: Guaranteed to be original equipment, often includes programming in the purchase price, and they have the necessary dedicated tools.
  • Cons: Often the most expensive option. Expect to pay anywhere from $150 to $300 or more for the remote and programming.

• Locksmith Specializing in Commercial Vehicles:

  • Pros: Often more cost-effective than a dealership, many can provide and program aftermarket remotes that function identically to OEM, and they can come to you (mobile service).
  • Cons: Not all locksmiths have the necessary software for heavy-duty trucks. Ensure they specify experience with Peterbilt.
  • Cost Expectation: Typically $100 to $250 for the remote and programming, depending on the complexity.

• Online Retailers (e.g., Amazon, eBay):

  • Pros: Can find remotes at a significantly lower upfront cost.
  • Cons: You need to verify compatibility carefully, as Peterbilt remotes can be specific. You will still need a dealer or specializing locksmith to program it, adding to the overall cost. There's also a risk of receiving a non-functional or counterfeit remote.
  • Cost Expectation: A remote alone might be $30 to $80, but remember programming is an additional cost.

If On-Board Programming Isn't Supported

Since on-board programming is not an option for your 2017 Peterbilt 389, you will need to rely on professional services. The cost expectation for programming alone (if you provide the remote) can range from $50 to $150 at a dealership or locksmith. This fee covers their time, expertise, and the use of their specialized diagnostic equipment.

Regarding the immobilizer transponder, Peterbilt trucks utilize a sophisticated immobilizer system that is integrated into the vehicle's electronic control units (ECUs). When a new remote is programmed, the transponder chip inside the remote (if applicable for your specific remote type, as some Peterbilt remotes are purely for keyless entry and the key blade handles immobilizer) must be recognized by the vehicle's immobilizer system. This typically occurs as part of the overall programming procedure performed by a dealer or a locksmith with the appropriate software. The complexity of these systems is another reason why DIY programming is not feasible for this model.
