2023 Ram 1500 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2023 Ram 1500 does not support DIY on-board programming for its key fobs. Due to the advanced security systems and immobilizer technology in modern vehicles, a specialized scan tool is required to program new key fobs to your Ram 1500. This procedure typically involves accessing the vehicle's onboard computer and syncing the new fob with the existing system. This can only be done by a certified automotive locksmith or a Ram dealership.

Battery replacement

Replacing the battery in your 2023 Ram 1500 key fob is a straightforward process:

1. Locate the small release button or switch on the side or back of the key fob. Press it to release the emergency key, then pull the emergency key out.
2. With the emergency key removed, you should see a small slot or notch. Use a small, flat-head screwdriver or a coin to carefully pry open the two halves of the key fob casing.
3. Gently separate the two halves. You'll see the circuit board and the battery.
4. Note the orientation of the old battery (CR2450) before removing it. Use your screwdriver or a similar tool to carefully pop out the old battery.
5. Insert the new CR2450 battery with the positive (+) side facing up, matching the orientation of the old battery.
6. Carefully align the two halves of the key fob casing and press them back together until they click securely into place.
7. Reinsert the emergency key into the fob.

Where to buy a replacement fob

When considering where to purchase a replacement key fob for your 2023 Ram 1500, you have a few options, each with its pros and cons:

• Ram Dealership:

  • Pros: Guaranteed to be an OEM part, often comes with a warranty, and they have the necessary tools for programming.
  • Cons: Most expensive option. Expect to pay anywhere from $250 to $400 or more for the fob and programming.

• Automotive Locksmith:

  • Pros: Often more affordable than the dealership, can come to your location (mobile locksmiths), and have the specialized equipment for programming.
  • Cons: Prices can vary, ensure they are reputable and experienced with modern Ram vehicles.
  • Ballpark Price: Typically $150-$300, including the fob and programming.

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

  • Pros: Potentially the cheapest option for the fob itself.
  • Cons: You're responsible for ensuring the fob is compatible (matching FCC ID and part number is crucial). You'll still need a locksmith or dealer to program it, adding to the overall cost. Beware of counterfeit or low-quality fobs.
  • Ballpark Price: Fob only could be $50-$150, but programming costs will be additional.

If on-board programming isn't supported

As mentioned, the 2023 Ram 1500 requires a scan tool for key fob programming. This means you'll need to factor in the cost of professional programming, whether from a dealership or an automotive locksmith. The immobilizer system in your Ram 1500 uses an advanced transponder chip embedded within the key fob. This chip communicates with your vehicle's computer to ensure only authorized keys can start the engine, providing a significant layer of anti-theft security. When a new key fob is programmed, its unique transponder code is registered with the vehicle's immobilizer system.

Cost Expectations:

• Dealership: As noted above, expect the highest cost due to labor rates and markup on parts.
• Locksmith: Generally a more budget-friendly alternative. They often charge a flat fee for programming, which can be combined with the cost of a replacement fob if you purchase one through them.

Always confirm the total cost, including the fob, emergency key cutting, and programming, before committing to a service.
