My Dodge Ram's keyless entry system is not functioning properly. Can you please help me figure out why?

If the keyless entry FOB for your Dodge Ram isn't working, the first step is to check the small lithium battery inside the FOB itself. These batteries have a lifespan of just a few years and are prone to failure. The FOB for your Ram uses a CR2032 (the same type found in most computers) and a replacement can be purchased for about $5 or less. If the FOB battery is not the issue, it could be the battery in the Ram itself. A weak battery in the vehicle may not provide enough power to unlock the doors, so make sure to check the voltage on the main battery. If those steps don't resolve the problem, you may need to check if the vehicle has lost sync with the key. In this case, manually unlock the doors and drive the Ram to the nearest dealership for further assistance.
