2016 Ram 1500 Key Fob Programming

Quick reference

Step-by-step on-board programming

Unfortunately, the 2016 Ram 1500 does not offer an on-board (DIY) programming procedure for new key fobs. This is because the key fob also contains the immobilizer transponder chip, which must be paired to the vehicle's computer using specialized diagnostic equipment. This security measure prevents unauthorized individuals from easily programming a new key and stealing the truck.

To program a new key fob, you will need to use a diagnostic scan tool capable of accessing the 2016 Ram 1500's immobilizer system. This means you will need to have the key programmed by a dealership service center or an automotive locksmith.

Battery replacement

Replacing the battery in your 2016 Ram 1500 key fob is a simple task you can do at home.

1. Separate the key: Press the small silver button on the side of the fob to release the physical key blade.
2. Pry open the case: Use a small flathead screwdriver or a pry tool to carefully separate the two halves of the key fob case. There is usually a small indentation where you can insert the tool.
3. Remove the old battery: The battery is a CR2032 coin cell. Note the orientation of the positive (+) and negative (-) sides.
4. Insert the new battery: Place the new CR2032 battery into the fob, making sure it is oriented the same way as the old one.
5. Snap the case together: Reassemble the two halves of the key fob and snap them securely together.
6. Re-insert the key: Slide the physical key blade back into the fob until it clicks into place.

Where to buy a replacement fob

• Dealership: The most expensive option, but you are guaranteed to get a genuine OEM fob. Expect to pay $150–$250 for the fob itself, plus another $100–$150 for programming.
• Automotive Locksmith: Locksmiths can usually source OEM or high-quality aftermarket fobs for a lower price than the dealer. They also have the equipment to cut and program the key. This is often the most convenient and cost-effective option. Expect to pay $100–$200 for the fob and programming.
• Amazon/eBay: You can find many affordable aftermarket fobs online, some for as little as $20. However, the quality can be inconsistent, and you will still need to find a locksmith or dealer to cut and program the key.

If on-board programming isn't supported

As mentioned, the 2016 Ram 1500 requires specialized equipment to program a new key fob. The key contains a transponder chip that communicates with the vehicle's immobilizer system. Without proper programming, the truck will not start, even if the key blade is cut to match.

When you take your truck to a locksmith or dealer, they will use a scan tool to connect to the vehicle's computer via the OBD-II port. They will then initiate a key programming sequence that pairs the new transponder chip to the immobilizer. The entire process usually takes about 15–30 minutes.
