It comes with all the standard gadgets - crowd-pleasers like motorised doors that shut at the touch of a button, and umbrellas that are hidden inside the door opening. It comes with an efficient V12 engine that can be driven in almost silence.
Dead Coin Battery
A dead coin battery is the most common cause of a key fob not locking or unlocking the doors. It's also one of the simplest to fix because it can be replaced in a few minutes. Make sure to use a new coin battery that has the same voltage, size, and specifications as the first to avoid a damaged battery. Also, do not use a battery that has been exposed to clean water (rain or clean tap water, or soda) because this could damage the internal chip. If the key fob still isn't working, try reprogramming the key using an original key or visit an authorized dealer.
Water damage, Receiver Module issues, Signal Interference, and a damaged electronic chip are all other reasons for why the key fob might not work.
Contact with the Battery is Poor

But, ensure that you only replace it with a brand new battery with the same voltage and size. If you're unsure of what kind to buy, ask an employee at your local auto parts store.
Corrosion on the battery terminals of the battery terminals in a Rolls Royce Dawn can also prevent it from beginning. This is a problem that is common with older batteries, particularly when they haven't been charged for a prolonged period of time. To check if your battery terminals are corrosion free you can utilize a multimeter to test the conductivity. Set the meter on ohms, and place one of the probes against the negative terminal of your Dawn. Then, touch the other probe to a bare metal part of the chassis or engine. The reading should be close to zero ohms.
Another sign of a weak battery in your Dawn is the sound that you hear when you attempt to start the engine. This is because starter solenoid, the accessories and the engine require low current while the starter solenoid requires high current.
Water Damage
If you dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it's probably damaged by water. rolls royce key price are protected by rubber seals but prolonged exposure to clean water or salty ocean water could cause it to stop working.

It can also interfere in the signal transmission, leading to the failure of remote keyless systems. The key fob may even disable your vehicle or activate the immobiliser system, leaving you in a bind.
To prevent this from happening, remove the key fob from its case and wipe it clean with a an abrasive towel to eliminate any moisture. You can also place the key in a bag filled with uncooked silica gel or rice to absorb any moisture. Once dry the key should function normally again. If the key fails to work, it is most likely that the 12 volt batteries or the receiver modules are the cause. These need to be reprogrammed.
Issues with Receiver Modules
If you've tried a different battery, but the remote key fob still doesn't work, it may be time to replace the receiver module. The receiver module 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 the module won't be able communicate with the other modules of the vehicle. To determine the cause, you'll need an OBD scanner to 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 contact ineffective. When replacing the battery, ensure that it is the exact same size and voltage as the original. Otherwise, it could damage the chip inside the key fob.
Water damage may be the reason behind a key fob that suddenly stopped working. This could happen if the key fob is dropped into water or gets wet with soapy water. You can try to clean the key fob by using isopropyl alcohol or electronic cleaners, but if you find that the chip in the key fob is damaged, you'll need to replace it.
Signal Interference
Occasionally, your Dawn key fob may stop working due to signal interference. Interference could be due to objects near your vehicle or weather conditions, as well as transmitters using the same frequency band. It could result from a defective receiver module. If you're unable to eliminate the interference, you may want to try using an extender of range or signal booster.
If the battery for the button cell is completely depleted then it's time to replace it. The battery should be the same voltage, size and type as the original battery to ensure that your vehicle remains compatible with the key fob. If your key fob begins 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 for an expert locksmith. A reputable locksmith will be able to help you with any Rolls Royce key fob or key programming requirements, including the reprogramming and replacement. They can give you an estimate of the work required. Request the locksmith's rates and credentials prior to hiring them.
Dead 12 Volt Battery
The 12 volt battery inside your Rolls Royce Dawn is responsible to provide high electrical current, not only to start the engine, but also to power all accessories and on-board computers. If the battery is in a dead state or the flow of power to the engine is interrupted due to corrosion of the battery's terminals, or the ground connection, all electronics onboard including the remote keyless system will stop functioning.
To test the condition of your Dawn battery you can conduct the test of conductivity using a multimeter. To perform this test you must disconnect 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 part of the vehicle's engine, body or chassis. The reading should be in the vicinity of zero ohms.
If the results are not satisfactory then replace the battery with an alternative battery that has the same voltage, size, and specification. Make sure that you fully charge the replacement battery prior to using it. The most frequent cause of the battery failing is internal degradation as a result of the aging process. However, it can also occur as a result an unnatural draw or if your vehicle has been parked for a long time.
