This component receives radio frequency signals from your key fob, and converts them to commands for the vehicle's electronic system. If the chip inside the module is damaged, it will not be in a position to communicate with other modules inside the vehicle. To determine the cause you'll need an OBD scanner that will reveal what the onboard computer is telling it to do.

The clips made of metal that hold the battery in the key fob of your Dawn complete the circuit and keep it in the right place. These clips can corrode and render the battery contacts ineffective.

The interference could be caused by objects in the vicinity of your vehicle, weather conditions and transmitters that operate on the same frequency band. Interference can result from a defective receiver module. If you can't resolve your problem by cutting down on the amount of interference, you could try using an amplifier or range extender.

It is essential to replace the button cell battery in your Dawn key fob in the event that it's drained. The battery must be the same voltage, size and type as the original battery in order to ensure that your vehicle is compatible with the key fob.
