How to Fix Rolls Royce Dawn Key Fob Problems
There aren't many cars that provoke the sort of involuntary gasp that the Rolls-Royce Dawn does. Even with the roof made of cloth off, it's an impressive car.
It has all the hallmark gadgets - crowd-pleasers like motorised doors that close at the press of a button and umbrellas concealed in the door opening. It has an incredibly smooth V12 engine that can be driven in complete silence.
Dead Coin Battery
The most common reason for a key fob that does not lock or unlock the doors is a dead battery. It's also one of the easiest to fix as it can usually be replaced in a matter of minutes. To avoid the possibility of a defective coin battery, always make sure you use a new battery that has identical in size, voltage and specifications as the original one. Also, never use a battery that has been exposed to clean water (rain, clean tap water, or soda) because this could damage the internal chip. If the key fob still doesn't work you can try reprogramming it with an original key, or visit an authorized dealer.

This problem is common with older batteries, particularly in the event that they haven't been fully charged for a prolonged period of time. Multimeters are a good tool for checking the conductivity to determine if the battery terminals have corrosion. Set the meter to ohms and touch one of its probes to the negative terminal in your Dawn. Place the other probe on a bare metal surface of the chassis or engine. The reading should be near zero ohms.
Another symptom of a weak battery in your Dawn is clicking noise when you attempt to start the engine. This is because starter solenoid, the accessories and the engine require low voltage while the starter solenoid requires high current.

You can also place the key in an airtight container with uncooked rice or silica gel packets to soak up any moisture. Once the key is dry it should function normally again. If not, the issue is likely to be with the 12 volt battery or the receiver module, which requires reprogramming to fix.
Receiver Module Issues
If you've already tried a new battery and the remote key fob still isn't working, it could be time to replace the receiver module. This is the component that receives the radio frequency signals from the key fob, and converts them into commands for your car's electronics. If the chip inside the module is damaged, it will not be capable of communicating with other modules inside the vehicle. You'll need a scanner in order to identify the issue. It will reveal what the computer on the vehicle is telling it.
The battery in the key fob of your Dawn has metal retaining clips that keep it in place and complete the circuit. The clips may corrode and make the battery's contacts ineffective. When replacing the battery, make sure that it is the exact same size and voltage as the original. It could damage the chip in the key fob.
Water damage may be the reason behind an electronic key fob that suddenly stopped working. The key fob could be damaged by water if it is dropped into water or immersed in soapy water. You can try to clean the key fob using isopropyl alcohol or other electronic cleaners, but if you find that the chip in the key fob has gone out of service it will need to be replaced. it.
Signal Interference
Signal interference can cause your Dawn keyfob to stop working. Interference could be caused by objects in the vicinity of your car or by weather conditions, or transmitters that operate on the same frequency band. A defective receiver module can also cause interference. If you're unable to reduce the interference, you may want to try using an extender of range or signal booster.
It is essential to replace the button cell battery in your Dawn key fob if it is drained. The battery should be the same voltage, size and type as the original battery to ensure your vehicle remains compatible with the key fob. If your key fob ceases to work intermittently, it could indicate that the chip has gone out of service.
If you've tried all of the above, but your key is still unable to unlock or lock, it's time to call a locksmith. A reputable locksmith will be able to help you with any Rolls Royce key fob or key programming needs, such as the reprogramming and replacement. They will be able to give you an estimate of the work to be done. Request the locksmith's rates and credentials prior to hiring them.
Dead 12 Volt Battery
The 12 volt battery that is in your Rolls Royce Dawn is responsible for providing high electrical current, not only to start the engine but also to supply power to all accessories as well as on-board computers. The battery won't work in the event of a dead battery or if the flow of current is interrupted by corrosion of the battery's terminals or the ground connection.
A multimeter can be used to check the conductivity of your Dawn battery. To perform this test remove the negative cable from the battery and then touch 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 near zero Ohms.
If the results were not satisfactory then replace the battery with an alternative battery that has the same size, voltage, and specification.
