HOW TO PROGRAM A DODGE KEY FOB WITHOUT A WORKING ONE: A GUIDE

Each car has a unique tag programmed into the receiver and key fob. When you purchase a new key fob, it doesn’t have this tag since it hasn’t been programmed. In other words, it’s a blank key. This is why you often need the original key fob: to copy the tag from the original key into the transponder of the new key. Without the tag, the transponder in that new key won’t be able to communicate with the immobilizer in the car. As a result, the immobilizer will disable the ignition system, and the car won’t start. This programming process usually involves using a scan tool to connect to the car. As a safety measure, the system often requires the original key fob. This way, indecent people with bad intentions won’t be able to steal your car since they don’t have the original key fob.
