Few cars can create the kind of uncontrollable gasp that the Rolls-Royce Dawn can. Even with the cloth roof down, it's an impressive car.

It comes with all the standard features such as motorized doors that can be shut by pressing one button. Umbrellas are hidden in the door's openings. It also has a silky smooth V12 engine that is driven with a whisper.

Dead Coin Battery

The most frequent reason for a key fob that does not unlock or lock the doors is a dead coin battery. It is also one of the most simple problems to fix since it is usually replaced in a matter of minutes. To avoid the possibility of a defective coin battery, ensure that you make sure you use a new battery that is the same size, voltage and specifications as the first one. Also, never use the battery that has been exposed to clean water (rain, clean tap water, or soda) because this could cause damage to the internal chip. If the key fob still does not work try reprogramming the key using the original key or visit an authorized dealer.

This is a typical issue in older batteries, especially if they haven't been charged 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 at ohms and use one of its probes to connect to the negative terminal on your Dawn. Then, you can connect the other probe to a metal part of the chassis or engine. The reading should be close to zero ohms.

A clicking noise is another indicator of a weak Dawn battery. This is because the starter solenoid and accessories require a high amount of electric current while the engine requires a lower current to function. This means that the battery is unable to 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 probably to be suffering from water damage. The chip's electronic components are protected by rubber sealings but prolonged exposure to sea salt or clean water may cause it to cease functioning.

You can also place the key in an airtight bag with uncooked silica gel or rice packets to help to absorb any moisture that remains. Once the key has dried it should function normally again. If not, the problem is likely to be with the 12 volt battery, or the receiver module, which will require reconfiguring to fix the issue.

Issues with Receiver Modules

If you've already tried a new battery but the remote key fob still isn't working, it might be time to replace the receiver module. The receiver module receives radio frequency signals from your key fob and converts them to commands for the vehicle's electronic system. If the chip in the module is damaged it will not be able communicate with the other modules of the vehicle. You'll need a scanner in order to diagnose the problem. It will be able to show what the computer on the vehicle is telling it.

The metal clips that secure the battery in the key fob that you use for your Dawn complete the circuit and hold it in the right place. The clips may corrode and render the battery's contacts ineffective. When replacing the battery, be sure that it's exactly the same size and voltage as the original. Otherwise, it could damage the chip inside the key fob.

If the key fob stops suddenly, it could indicate that it has been damaged by water. This could happen if the key fob is dropped into water or is soaked by soapy water.

Interference could be due to objects near your car or weather conditions, as well as transmitters that operate on the same frequency band. A malfunctioning receiver module could also cause interference. If you are unable to reduce the interference, you may consider using a range extender or signal booster.

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

If you've tried all of the above methods but are still unable to unlock your key or lock, it's that you should call a professional locksmith. A reliable locksmith will be able help you with any Rolls Royce key fob or key programming requirements, including the reprogramming and replacement.
