It has all the hallmark devices - like motorised doors that shut at the touch of a button and umbrellas hidden in the door's opening. It also comes with a smooth V12 engine that is driven with a whisper.

Dead Coin Battery

A dead battery for a coin is the most common cause of a key fob that isn't locking or unlocking the doors. It is also one of the easiest to fix as it is usually replaced in a matter of minutes. To avoid a damaged coin battery, ensure that you make sure you use a new battery that has the same voltage, size and specification as the original one. Also, don't use batteries that have been exposed to clean water (rain or clean tap water or even soda) as this may damage the internal chip. If the key fob won't function after reprogramming it using an original key, visit an authorized dealer.

This problem occurs with older batteries, particularly when they haven't been charged for a prolonged period of time. You can use a multimeter for checking the conductivity to determine if your terminals on your battery have rust. Set the meter at ohms and use one of its probes to connect to the negative terminal on your Dawn. Then, touch the other probe to a bare metal part of the chassis or engine. The reading should be near zero ohms.

A click is another indicator of a weak 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 work - this means that the battery is unable to provide enough charge.

Water Damage

If you dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it's probably to be suffering from water damage. The chip's electronic components are protected by rubber seals but prolonged exposure to clean water or salty ocean water could cause it to cease functioning.

You can also place the key in an airtight container with uncooked silica gel or rice packets to to absorb any moisture that remains. Once dry the key should function normally again. If not, the issue is most likely due to the 12 volt battery, or the receiver module, which requires changing the program to fix it.

Receiver Module Issues

If you have tried a new cell and the remote keyfob still does not work, then it might be time to replace your receiver module. This is the component that receives the radio frequency signals from the key fob and converts them into commands for the car's electronic. If the chip inside the module is damaged, the module will not be able to communicate with other modules of the vehicle. You'll need a scanner to determine the issue. It will reveal what the computer on the vehicle is telling it.

The clips made of metal that hold the battery in the key rolls royce fob for your Dawn complete the circuit and keep it in position. These clips are susceptible to corroding and render the battery's contacts ineffective. When replacing the battery, be sure that it's the exact same size and voltage as the original. 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 in water or soaked in soapy water.

Interference can be caused by objects that are within the vicinity of your car or weather conditions, as well as transmitters operating on the same frequency band. A faulty receiver module can also cause interference. If you can't resolve your problem by decreasing the amount of interference, try using a signal booster or range extender.

If the button cell's battery is completely drained then it's time to replace it. To ensure compatibility with your vehicle, the battery should have the same voltage and size as the original. If your key fob ceases to work intermittently, it could mean the chip is fried.

If you've tried the above suggestions but still aren't able to get your key to unlock or lock, it's that you should call an experienced locksmith.

Dead 12 Volt Battery

The 12 volt battery in your Rolls Royce Dawn provides high current to start the engine and also for all the accessories and computers onboard. If the battery is in a dead state or the flow of power to the engine is disrupted due to corrosion on the battery's terminals, or the ground connection, all on-board electronics including the remote keyless system will stop working.

A multimeter can be used to check the conductivity of your Dawn battery. To accomplish this, 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 the vehicle's engine, body or chassis. The reading should be zero ohms, or close to it.

If the results are not satisfactory If the results are not satisfactory, you can replace the battery with a fresh one of the same voltage, size and specifications.
