2016 Ram 3500 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2016 Ram 3500 does not support DIY, on-board programming for its key fobs. The vehicle's security system requires specialized diagnostic equipment to program new key fobs. This means you will need to visit a dealership or a professional automotive locksmith to get a new fob programmed. Trying to use an on-board procedure will not work and could potentially cause issues with your vehicle's security system.

Battery replacement

Replacing the battery in your 2016 Ram 3500 key fob is a straightforward process:

1. Locate the release button/slot: On most 2016 Ram 3500 fobs, there will be a small button or slot on the side or back of the fob. Press the button or insert a small flathead screwdriver into the slot to release the emergency key.
2. Separate the fob halves: Once the emergency key is removed, you may see a seam running along the edge of the fob. Use a small flathead screwdriver or a pry tool in this seam and carefully pry the two halves of the fob apart. Be gentle to avoid damaging the internal components.
3. Remove the old battery: The CR2032 coin cell battery will be visible. Note its orientation (positive (+) side up or down) before removing it. Use the screwdriver or pry tool to carefully pop out the old battery.
4. Insert the new battery: Place the new CR2032 battery into the fob with the positive (+) side facing the same direction as the old battery.
5. Reassemble the fob: Carefully align the two halves of the key fob and press them together until they snap securely. Reinsert the emergency key.
6. Test the fob: Test all the functions of your key fob (lock, unlock, panic, remote start if applicable) to ensure it's working correctly.

Where to buy a replacement fob

When considering where to purchase a replacement key fob for your 2016 Ram 3500, you have a few options, each with its own advantages and disadvantages:

• Dealership:

  • Pros: Guaranteed genuine OEM part, often includes programming in the purchase price, and they can handle any associated immobilizer programming.
  • Cons: Most expensive option, typically ranging from $200-$400 for the fob and programming.

• Automotive Locksmith:

  • Pros: Can often provide and program OEM or high-quality aftermarket fobs, usually at a lower cost than the dealership (typically $150-$300). Many offer mobile services, coming to your location.
  • Cons: Ensure the locksmith is reputable and experienced with your vehicle's make and model.

• Online Retailers (e.g., Amazon, eBay, dedicated key fob sites):

  • Pros: Cheapest option for the fob itself (often $30-$80). Wide selection of both OEM and aftermarket options.
  • Cons: You will still need to pay for programming separately from a locksmith or dealer, which adds to the overall cost. There's also a risk of purchasing a low-quality or incompatible aftermarket fob. Always verify FCC ID and part numbers.

If on-board programming isn't supported

As mentioned, on-board programming is not available for the 2016 Ram 3500. This means that a specialized scan tool is required to communicate with your truck's body control module (BCM) and program the new key fob. This process involves pairing the new fob with your vehicle's immobilizer system.

Immobilizer Transponder

Your 2016 Ram 3500 uses an immobilizer system that requires a transponder chip embedded within the key fob to be recognized by the vehicle. Without proper programming of this transponder, the truck will not start, even if the key blade is cut correctly and the remote functions (lock/unlock) work. This security feature prevents theft and requires professional tools to correctly program.

Cost Expectations

Given the need for professional programming:

• If you purchase a fob online: Expect to pay for the fob itself (e.g., $30-$80) plus an additional $75-$150+ for programming by a locksmith or dealership. This can bring your total cost to $105-$230+.
• If you go directly to an automotive locksmith: The total cost, including the fob and programming, will likely be in the $150-$300 range.
• Dealership: As noted, expect the highest cost, often $200-$400, but it might be more convenient or your only option depending on your location and circumstances.
