2019 Ram 1500 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2019 Ram 1500 does not support DIY on-board key fob programming. This is a security measure implemented by Stellantis (formerly FCA) to prevent unauthorized key duplication and vehicle theft. The vehicle's immobilizer system requires specialized diagnostic equipment to program new key fobs.

Because of this, you will need to take your vehicle to a certified Ram dealership or a professional automotive locksmith for key fob programming. They have the necessary tools and software to communicate with your truck's body control module (BCM) and securely add new key fobs to its system.

Battery Replacement

Replacing the battery in your 2019 Ram 1500 key fob is a straightforward process:

1. Locate the emergency key release: On the side or bottom of your key fob, you'll see a small button or switch. Press it to release the emergency key blade. Pull the key blade out.
2. Separate the two halves of the fob: With the emergency key removed, you'll see a small slot or indentation. Carefully use a small flat-head screwdriver or a coin to gently pry apart the two halves of the key fob. Be gentle to avoid damaging the plastic casing.
3. Remove the old battery: Once opened, you'll see the CR2450 coin cell battery. Note its orientation (positive side up or down) and carefully pry it out.
4. Insert the new battery: Place the new CR2450 battery into the compartment, ensuring it's oriented correctly (matching the old battery's positive and negative terminals).
5. Reassemble the key fob: Carefully press the two halves of the key fob back together until they snap securely into place. Reinsert the emergency key blade.

Test the new battery by attempting to lock and unlock your vehicle from a distance.

Where to buy a replacement fob

When considering where to purchase a replacement key fob for your 2019 Ram 1500, you have several options, each with pros and cons:

• Ram Dealership:
  • Pros: Guaranteed genuine OEM part, often comes with programming included in the price, expert service.
  • Cons: Most expensive option, typically costing $300-$500 or more for the fob and programming.
• Automotive Locksmith:
  • Pros: Often significantly cheaper than the dealership (typically $200-$350 for the fob and programming), convenient mobile services available, experienced with a wide range of vehicles.
  • Cons: Ensure they use quality aftermarket or OEM equivalent fobs; always verify their credentials and reviews.
• Online Retailers (e.g., Amazon, eBay, specialized automotive key sites):
  • Pros: Cheapest option for the fob itself (often $50-$150), wide selection of OEM and aftermarket parts.
  • Cons: You'll still need to pay a locksmith or dealer for programming (an additional $100-$200), risk of receiving counterfeit or incompatible fobs, no recourse if the fob is faulty and cannot be programmed.

Given that the 2019 Ram 1500 requires professional programming, purchasing an aftermarket fob online and taking it to a locksmith is often the most cost-effective solution, providing you verify the fob's compatibility and quality.

If on-board programming isn't supported

As mentioned, the 2019 Ram 1500 does not have an owner-programmable on-board procedure for key fobs. This means you will need professional assistance to add new fobs or replace existing ones.

Cost Expectations: As detailed above, expect to pay between $200 and $500 for a new key fob and programming, depending on whether you go through a dealership or an independent automotive locksmith. This cost typically includes the key fob itself, the programming service, and potentially the cutting of the emergency key blade.

Immobilizer Transponder: The 2019 Ram 1500 key fob contains an integrated immobilizer transponder chip. This chip communicates with the vehicle's immobilizer system, which is a security feature that prevents the engine from starting unless the correct chip is detected. When a new key fob is programmed, the transponder chip is also registered with the vehicle's immobilizer system. This is why specialized diagnostic equipment is required for programming, as it links the unique identifier of the transponder to your truck's BCM.
