Dead Coin Battery
A dead battery for a coin is the most common reason of a key fob that isn't locking or unlocking the doors. It is also the simplest to fix since it can be replaced in just several minutes. To avoid the possibility of a defective coin battery, make sure you use a new battery that has the same voltage, size and specifications as the first one. Do not expose a battery to pure water, such as rain, clean tap-water, or even soda, because it could cause damage to the internal chip. If the key fob does not work after reprogramming it with an original key, visit an authorized dealer.

This is a common problem in older batteries, particularly when they haven't been recharged in a long period of. To check if your battery terminals are corrosion free, you can use a multimeter to check the conductivity. Set the meter to ohms, and place one probe against the negative terminal of your Dawn. Place the other probe on a bare metal surface of the engine or chassis. The reading should be close to zero ohms.
A click is another sign of an insufficient Dawn battery. This is due to the fact that the starter solenoid and accessories require high electric current, while the engine requires low current to operate. This means that the battery is unable to supply enough charge.
Water Damage
Water damage could be a result of dropping your Rolls Royce Dawn Key Fob in the sink or leave it in the rain. Although the electronic chip inside is protected by rubber seals, prolonged exposure to clean tap water or salty ocean water could cause it to stop working properly.
Over time water can cause corrosion, which results in faulty circuitry which can cause issues with the car's security and ignition systems. It can also interfere with the transmission of signals, causing the remote keyless system to fail. The key fob could lock your vehicle or activate the immobiliser system, leaving you without a vehicle.
To stop this from occurring, take off the key fob and wipe it clean with a damp cloth to dry any remaining moisture. You can also put the key in a bag that is airtight with uncooked silica gel or rice packets to help absorb any residual moisture. Once dry, the key should work normally again. If the key does not function, it is possible that the 12 volt batteries or the receiver modules are the cause. These need to be reprogrammed.
Receiver Module Issues
If you've already tried a new battery and the remote key fob isn't working, it could be time to replace the receiver module. This is the component that receives radio frequency signals from the key fob and transforms them into commands for your vehicle's electronics. If the chip in the module is damaged, the module 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.

These clips are susceptible to corroding and cause the battery contacts to become ineffective. If you are replacing the battery, ensure that it's the exact size and voltage to the previous one. It could damage the chip in the key fob.
Water damage may be the cause of the key fob suddenly stopped working. The key fob could be damaged by water if it is dropped in water or soaked in soapy water. You can try cleaning the key fob by using isopropyl alcohol or other electronic cleaners, but if the chip in the key fob has gone out of service you'll have to replace it.
Signal Interference
Signal interference could cause your Dawn keyfob to stop working. Interference can be caused by objects within the vicinity of your car, weather conditions and transmitters operating on the same frequency band. A faulty receiver module can also cause interference. If you are unable to resolve your problem by reducing the amount of interference, you could try using an amplifier for signal or a range extender.
It is crucial to replace the button cell battery in your Dawn key fob in the event that it's drained. To ensure compatibility with your vehicle, the battery must be the same voltage and size as the original. If your key fob ceases to malfunction intermittently, it may indicate the chip is damaged.
If you have tried all the above and your key doesn't seem to be unlocking or lock, it's time to call a locksmith. A reliable locksmith will be able help you with any Rolls Royce key fob or key programming needs, such as the reprogramming and replacement. They can give you an estimate of the work to be done.

Dead 12 Volt Batterie
The 12 volt battery that is in your Rolls Royce Dawn is responsible for providing high electric current, not just to start the engine, but also to provide power to all accessories and on-board computers. If this battery is dead, or the current flow to the engine is disrupted because of corrosion on the battery's terminals or ground connection, all on-board electronics including the remote keyless system will stop functioning.
To check the condition of your Dawn battery, you can perform the test of conductivity using a multimeter. To accomplish this you must disconnect the negative cable from the battery and then connect one probe of the multimeter to the ground wire of the battery, and the other probe to any exposed metal component of your vehicle's engine, body or chassis. The reading should be close to zero ohms.
If the results weren't satisfactory then replace the battery with a new one with the same size, voltage and specifications. Make sure the replacement is fully charged prior to use it.
