2018 Ram 1500 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2018 Ram 1500 does NOT support DIY on-board programming for key fobs. This vehicle utilizes a more advanced security system that requires specialized diagnostic equipment to program new key fobs. This means you will need to take your truck to a dealership or a qualified automotive locksmith to have a new key fob programmed.

The programming process typically involves:

1. Connecting a specialized scan tool to your vehicle's OBD-II port.
2. Accessing the vehicle's security system module.
3. Following a series of prompts on the scan tool to add a new key fob. This often involves entering a security PIN for the vehicle.
4. Testing the new key fob to ensure all functions (lock, unlock, remote start, etc.) are working correctly.

Attempting to program a key fob without the proper tools could potentially disable your existing keys or even damage the vehicle's security module, so it's best to leave this to the professionals.

Battery replacement

Replacing the battery in your 2018 Ram 1500 key fob is a straightforward process:

1. Locate the emergency key release: On the side of your key fob, you'll find a small button. Press and hold this button while pulling out the emergency key blade.
2. Separate the fob halves: With the emergency key removed, you'll see a small slot or indentation where the two halves of the key fob meet. Use a small, flat-head screwdriver or a coin to carefully pry the two halves apart.
3. Remove the old battery: Gently lift out the old CR2032 coin cell battery.
4. Insert the new battery: Place a new CR2032 battery into the compartment, ensuring the positive (+) side is facing up.
5. Reassemble the fob: Carefully snap the two halves of the key fob back together until you hear a click. Reinsert the emergency key blade.

Where to buy a replacement fob

When it comes to purchasing a replacement key fob for your 2018 Ram 1500, you have a few options:

• Dealership:
  • Pros: Guaranteed genuine OEM part, often includes programming in the purchase price, comprehensive warranty.
  • Cons: Most expensive option. Expect to pay anywhere from $250 to $400 or more for the fob and programming.
• Automotive Locksmith:
  • Pros: More affordable than a dealership, often mobile services available, can program both OEM and aftermarket fobs.
  • Cons: Quality of aftermarket fobs can vary. Prices typically range from $150 to $300 for the fob and programming.
• Online Retailers (e.g., Amazon, eBay):
  • Pros: Potentially the cheapest option for the fob itself.
  • Cons: You're only buying the physical fob; you'll still need to pay for programming. Risk of purchasing counterfeit or incompatible fobs. Prices for the fob alone can range from $50 to $150. Be very careful to verify the FCC ID and part numbers match your original fob.

If on-board programming isn't supported

As established, on-board programming is not an option for the 2018 Ram 1500. This means you will need professional assistance. The total cost will involve both the key fob itself and the programming service. Expect to pay an automotive locksmith between $150 and $300, and a dealership between $250 and $400 for a new key fob and its programming.

It's important to note that the emergency key blade within your fob will also need to be cut to match your vehicle's ignition and door locks. This is typically done by the locksmith or dealership at the time of programming. The 2018 Ram 1500 uses a rolling code immobilizer transponder system, which is a sophisticated anti-theft measure that requires professional tools to properly integrate a new key fob with your vehicle's computer.
