Step-by-step on-board programming
The 2018 Peterbilt 579 does not have an on-board programming procedure for key fobs. Programming a new key fob requires a diagnostic scan tool that can access the truck's computer system. This is a security measure to prevent unauthorized access to the vehicle.
To program a new key fob, you will need to take your truck to a Peterbilt dealer or a qualified locksmith with the proper equipment. They will hook up a scan tool to the OBD-II port in your truck and use it to program the new fob to the truck's computer.
Battery replacement
Replacing the battery in your 2018 Peterbilt 579 key fob is a simple process you can do yourself.
- Locate the small slot on the side of the key fob.
- Use a small flathead screwdriver or a coin to gently pry the two halves of the fob apart.
- Remove the old CR2032 battery, paying attention to the orientation of the positive and negative terminals.
- Insert the new CR2032 battery in the same orientation as the old one.
- Snap the two halves of the fob back together.
Where to buy a replacement fob
- Peterbilt Dealer: The dealer is the most expensive option, but you are guaranteed to get a genuine OEM key fob that is compatible with your truck. Expect to pay around $150-$250 for the fob and another $50-$100 for programming.
- Locksmith: A qualified locksmith can often get you a new key fob for a lower price than the dealer. They may have OEM or high-quality aftermarket fobs available. Expect to pay around $100-$200 for the fob and programming.
- Amazon: You can find a wide variety of aftermarket key fobs on Amazon for as little as $20. However, the quality of these fobs can vary, and you may have trouble finding a locksmith who is willing to program a fob that you have purchased online. If you choose to go this route, be sure to read the reviews carefully and purchase from a reputable seller.
If on-board programming isn't supported
As mentioned above, the 2018 Peterbilt 579 does not have an on-board programming procedure for key fobs. This means that you will need to take your truck to a dealer or a qualified locksmith to have a new fob programmed.
The reason for this is that the key fob contains a transponder chip that is part of the truck's immobilizer system. The transponder chip communicates with the truck's computer to verify that the correct key is being used. If the transponder chip is not programmed to the truck, the engine will not start.
