To avoid getting a faulty coin battery, ensure that you use a new battery that has the same size, voltage and specifications as the original one. Never use a battery exposed to clean water, like rain, clean tap water, or even soda, as this could damage the internal chip. If the key fob isn't working, try reprogramming the key using an original key or visit an authorized dealer.

This is a typical issue in older batteries, especially those that haven't been charged for a long period of time. To check if your battery terminals aren't corroded, you can utilize a multimeter to test the conductivity. Set the meter at Ohms, and place one probe against the negative terminal of your Dawn. Place the other probe on a metal surface of the chassis or engine. The reading should be near zero ohms.
A clicking noise is another sign of a weak Dawn battery. This is due to the fact that the starter solenoid as well as other components require high electric current, while the engine needs a low current to work - this means that the battery cannot provide enough charge.
Water Damage
If you accidentally dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it is likely suffering from water damage. The electronic chip is protected by rubber sealings but prolonged exposure to sea salt or clean water could cause it to stop working.

You can also put the key in an airtight container with uncooked silica gel or rice packets to soak up any moisture. After drying the key should function normally again. If the key does not work, it is most likely that the 12 volt batteries or the receiver modules are responsible for the problem. These modules must be replaced.
Issues with Receiver Modules
If you've tried a different cell but the remote key fob does not work, then it might be time to replace the receiver module. This component receives radio frequency signals from your key fob, and converts them into commands for the car's electronic system. If the chip in the module is damaged it will not be able communicate with the other modules of the vehicle. To identify the issue, you'll need an OBD scanner that will determine what the on-board computer is telling it to do.
The metal clips that secure the battery in the key fob for your Dawn complete the circuit and hold it in position. These clips are susceptible to corroding and render the battery contacts ineffective. If you are replacing the battery, make sure it's an exact match in size and voltage to the original one. Otherwise it could cause damage to the chip inside the key fob.
If the key fob stops suddenly, it could be an indication that it has been damaged by water. The key fob can be damaged by water if dropped into water or soaked in soapy water.
