Changing the battery in your Ram 3500 key fob is a simple task that can save you both time and money. In this guide, I will walk you through the steps to replace the battery in the key fob for the 2019, 2020, and 2021 models.

This guide will ensure you have a fully functioning key fob without the need to visit a dealership. Let’s get started!

Required Tools and Materials

Before we begin, you’ll need a few items. These tools and materials are essential for a smooth battery replacement process.

• CR2450 Coin Battery
• Precision Screwdriver
• Optional: Regular Screwdriver

You can find the CR2450 battery and precision screwdrivers on Amazon.

Step-by-Step Guide

Remove the Internal Key

First, locate the button on the right side of the key fob. Press and hold this button to release the internal key. Once released, set the key aside as we’ll need it later.

Lift Off the Back Cover

Next, focus on the back part of the key fob. This is a thin piece of plastic that we need to lift off. You’ll notice two small holes, one on the left and one on the right.

Using a Precision Screwdriver

Insert the precision screwdriver into the left hole. Push it in and gently pry up until you hear a pop. This indicates that the left side is starting to come loose. Repeat this process on the right side. Once both sides are loose, you should be able to pull the cover apart with your fingers.

Using a Regular Screwdriver

If you don’t have a precision screwdriver, a regular one will work too. Insert the screwdriver into the hole and gently twist it like a key until you hear a pop. Repeat on the other side. Be careful to avoid damaging the plastic.

Remove the Old Battery

With the back cover removed, you now have access to the battery compartment. Use your fingernails or a screwdriver to carefully lift out the old CR2450 battery.

Insert the New Battery

Take your new CR2450 battery and place it into the compartment with the positive side facing up. Ensure it’s securely in place by pressing it down gently.

Reassemble the Key Fob

Now, align the back cover with the key fob and press it firmly until it clicks into place. Finally, insert the internal key back into its slot.

Conclusion

And that’s it! You’ve successfully replaced the battery in your Ram 3500 key fob. This simple process can be done in just a few minutes, saving you a trip to the dealership.
