Touch the other probe on a bare metal surface of the engine or chassis. The reading should be near zero ohms.

Another indication of a weak battery in your Dawn is the sound that you hear when you try to start the engine.

You can also place the key in a bag with uncooked silica gel or rice to absorb any moisture. After the key has dried, it should function normally again. If not, the issue is most likely with the 12 volt battery, or the receiver module, which requires reprogramming to fix.

Receiver Module Issues

If you have tried a new phone but the remote key fob does not function, then it may be time to replace the receiver module. This component receives radio frequency signals from your key fob, and converts them to commands for the vehicle's electronic system.
