There are few vehicles that generate the kind of involuntary gasp that the Rolls-Royce Dawn does. Even with the cloth roof down, it's an impressive car.

It comes with all the usual features, including motorised doors that can be closed at the push of a button. Umbrellas are concealed in the openings of the doors. It is equipped with an efficient V12 engine that can be driven in almost silence.

Dead Coin Battery

The most frequent reason for a key fob to not lock or unlock the doors is a dead coin battery. It is also among the easiest to fix as it is usually replaced in a matter of minutes. Make sure to use a new coin battery that is the same voltage, size, and specification as the original to avoid a faulty battery. Also, never use a battery that has been exposed to clean water (rain, clean tap water, or even soda) since this can cause damage to the internal chip. If the key fob doesn't work after reprogramming it using an original key, you can visit an authorized dealer.

This issue occurs with older batteries, especially if they haven’t been charged for a prolonged period of time. To determine if your battery's terminals are corrosion free, you can use a multimeter to check the conductivity. Set the meter on Ohms, and place one of the probes against the negative terminal of your Dawn. Then, you can connect the other probe to a bare metal part of the engine or chassis. The reading should be close to zero ohms.

A click is another indicator of weak Dawn battery. This is due to the fact that the starter solenoid and other accessories require high electric current, while the engine needs a low current to work - this means that the battery cannot supply enough charge.

Water Damage

If you accidentally dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it's likely damaged by water. Although the electronic chip inside is protected by rubber seals, prolonged exposure to pure tap water or salty ocean water can cause it to stop functioning properly.

If the key fails to function, it is possible that the 12 volt batteries or the receiver modules are the cause. They must be changed.

Receiver Module Issues

If you've tried a new phone but the remote key fob does not work, it could be time to replace the receiver module. This is the component that receives radio frequency signals from the key fob and converts them into commands for your car's electronic. If the chip inside the module is damaged, it will not be capable of communicating with other modules in the vehicle. To diagnose the problem you'll need an OBD scanner that can determine what the on-board computer is telling it to do.

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 render the battery's contacts ineffective. If you are replacing the battery, ensure that it's an exact match in size and voltage to the previous one. Otherwise it could cause damage to the chip inside the key fob.

If the key fob stopped suddenly it could be a sign that it was damaged by water. The key rolls royce fob may be damaged by water if it is dropped into water or soaked in soapy water.

Signal Interference

Signal interference can cause your Dawn keyfob to stop functioning. The interference could be caused by objects that are within the vicinity of your vehicle, weather conditions and transmitters that operate on the same frequency band. A malfunctioning receiver module could also cause interference. If you are unable to resolve your issue by reducing the amount of interference, try using an amplifier for signal or a range extender.

It is essential to replace the button cell battery on your Dawn key fob in the event that it's depleted. The battery should be the same size, voltage and type as the original battery in order to ensure that your vehicle remains compatible with the key fob. If your key fob ceases to fail intermittently, it may indicate that the chip has gone out of service.

Dead 12 Volt Battery

The 12 volt battery inside your Rolls Royce Dawn provides high current to start the engine, but also for all onboard computers and accessories. If the battery is dead or the flow of power to the engine is disrupted because of corrosion on the battery's terminals or ground connection, all electronic components on board including the remote keyless system will cease to function.

To check the condition of your Dawn battery it is possible to conduct the test of conductivity using a multimeter. To do this, take off the negative cable of the battery and connect one probe of the Multimeter to ground wire of the battery. Then, touch the other probe of the Multimeter to any exposed metal components of your vehicle, like the body, chassis or engine. The reading should be near zero Ohms.

If the results aren't satisfactory If the results are not satisfactory, you can replace the battery with a new one of the same voltage, size and specifications. Make sure you fully charge the replacement battery prior to using it. The most frequent cause of an unreliable battery is internal degeneration due to the aging process.
