The future is an exciting time. It brings us technological wonders like automatic emergency braking, pedestrian detection, and electronic key fobs that let us start our cars, lock our doors, or even lower the tailgate from a distance. It all feels like a perfect world of technology until your car alerts you that your key fob battery is old, and suddenly you start to miss just having a regular metal key. Continue reading this entry to learn how to change the battery in a modern RAM key fob.

What Do I Need to Change the Battery in my RAM Key Fob?

Before you get started, you need to get a replacement battery. For RAM models from 2019 and on, you will need either a 2450 button battery or a CR 2032. The RAM 1500 should take the CR 2450, while the RAM 2500 and some trims might take the CR 2032. Battery sizes like these are easy to find online, at battery stores, or sometimes in grocery and convenience stores. You should also have a flathead precision screwdriver or something similar.

How Do I Open my RAM Key Fob?

To open your RAM Key Fob, press down on the silver button on the side of the fob, and pull up on the key ring. This should free the metal key out, and give you access to two small slots. Use a small screwdriver or other thin, dull metal object to pry the black plastic plate off the key fob. It will crackle and pop, but it should come off in one piece. Pay attention to the way the old battery is facing when you open the key fob.

How Do I Replace the Battery in my RAM Key Fob?

The old battery should be positioned with the positive end facing up. Use a small screwdriver or similar object to pop the old battery out, and put the new one in. Make sure the new one matches the old one’s number and direction. Most likely, for a RAM 1500, you should be putting a CR 2450 button battery in with the positive end facing up. Put the black plastic plate back on the key fob, pinch it closed, and put the key back in. Test your key fob, it should work. If not, make sure you got the right battery type, that it is facing the right way, and that the battery still has a charge.
