How to Fix Rolls Royce Dawn Key Fob Problems

There are few cars that provoke the sort of involuntary gasp the Rolls-Royce Dawn does. Even with the top-down cloth it's a stunning vehicle.

It comes with all the usual devices, including motorised doors that can be closed by pressing the button. Umbrellas are concealed within the door's openings. It is equipped with an efficient V12 engine that can be driven in almost silence.

Dead Coin Battery

The most common reason for a key fob to not unlock or lock the doors is a dead coin battery. It is also among the most simple problems to fix since it can be replaced in a matter of minutes. Use a new coin battery that has the same voltage, size and specification as the original to avoid a faulty battery. Don't expose a battery to pure water, such as rain, clean tap water or even soda, as it could cause damage to the internal chip. If the key fob doesn't work you can try reprogramming it with an original key, or visit an authorized dealer.

Other reasons the key fob might not be working include Water Damage, Receiver Module issues, Signal Interference and an Electronic Chip that is damaged.

Poor Battery Contact

The button cell battery on the key fob of your Rolls Royce Dawn may lose its charge. Replacing the battery is a quick and simple fix. Make sure you replace the battery with one that is the same size and voltage. Talk to an employee at the auto parts store if you aren't sure what type of battery to purchase.

Corrosion on the battery terminals in the battery terminals of a Rolls Royce Dawn can also stop it from starting. This issue occurs with older batteries, especially when they haven't been charged for a long amount of time. Multimeters are a good tool for checking the conductivity to see if your terminals on your battery have rust. Set the meter at ohms and touch one of its probes to the negative terminal on your Dawn. Then, you can connect the other probe to a plain metal part of the chassis or engine. The reading should be close to zero ohms.

Another symptom of a weak battery in your Dawn is clicking noise when you attempt to start the engine. This is due to the starter solenoid, the accessories and the engine require low voltage while the starter solenoid needs high current.

Water Damage

If you accidentally dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it's likely to be suffering from water damage. Although the electronic chip inside is protected by rubber seals, prolonged exposure to clean tap water or salty ocean water could cause it to stop working properly.

Moisture can cause corrosion over time, leading to malfunctioning circuits, which can lead problems with the security and ignition system of your car. It can also interfere with the transmission of signals, causing the remote keyless system to fail. The key fob may lock your car, or activate the immobiliser, leaving you stuck.

To avoid this, take the key fob from its case and wipe it clean with a a damp towel to remove any moisture. You can also put the key in a bag with uncooked silica gel or rice to absorb any moisture. After the key has dried it should function normally again. If the key does not work, it is most likely that the 12 volt batteries or the receiver modules are responsible for the problem. These modules must be reprogrammed.

Receiver Module Issues

If you've already tried a different battery, but the remote key fob still doesn't work, it may be time to replace the receiver module. This is the component that receives the radio frequency signals from the key fob and transforms them into commands for your 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 show you what the computer on the vehicle is telling it.

The clips made of metal that hold the battery in the key fob that you use for your Dawn complete the circuit and hold it in place. The clips may corrode and render the battery contacts ineffective. When replacing the battery, ensure 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 stopped working abruptly, it could be an indication that it was damaged by water. The key fob may be damaged by water if dropped into water or soaked in soapy water. You can clean the keyfob by using electronic cleaners or isopropylethanol, but you will need to replace the chip if it's fried.

Signal Interference

Signal interference can cause your Dawn keyfob to stop working. Interference can be caused by objects in 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 cut down on interference, you might want to try 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 should have the same size and voltage as the original. If your key fob ceases to fail intermittently, it could indicate that the chip has gone out of service.

If you've tried the previous tips and still can't get your key to unlock or lock, it's likely time to contact a professional locksmith. A reputable locksmith can assist you with all of your rolls royce key blanks Royce key fob and key programming needs. This includes reprogramming and replacement. They can give you an estimate of the work needed. Be sure to inquire with the locksmith about their rates and credentials before hiring them.

Dead 12 Volt Battery

The 12 volt battery inside your Rolls Royce Dawn is responsible to provide high electric current, not just to start the engine but also to supply power to all accessories as well as on-board computers. The battery will not function in the event of a dead battery or if the flow of current is interrupted due to corrosion of the battery's terminals or the ground connection.

You can use a multimeter to check the conductivity of your Dawn battery. To test this, you must remove the negative cable from the battery and connect one probe of the Multimeter to the grounding wire of the battery. Then, apply the other probe of the Multimeter to any exposed metal parts of your vehicle, like the body, chassis or engine. The reading should be in the vicinity of zero Ohms.

If the results were not satisfactory, replace the battery by another battery with the same size, voltage and specifications. Make sure the replacement is fully charged prior to use it. The most common cause of a faulty battery is internal degeneration due to the aging process. However, it can be caused by parasitic draw or if your vehicle has been parked for a long time.
