To avoid getting a faulty coin battery, make sure you make sure you use a new battery that has the same voltage, size and specifications as the original one. Also, never use a battery that has been exposed to clean water (rain, clean tap water, or even soda) since this can cause damage to the internal chip.

Receiver Module Issues

If you've tried a different battery, but the remote key fob isn't working, it could be time to replace the receiver module. This is the part that receives radio frequency signals from the key fob, and converts them into commands for the car's electronic. If the chip inside the module is damaged, it won't be able to communicate with other modules within the vehicle. To determine the cause you'll need an OBD scanner to determine what the on-board computer is telling it to do.

The metal clips that hold the battery in the key fob for your Dawn complete the circuit and keep it in place. These clips are susceptible to corroding and render the battery's contact ineffective.
