How to Fix Rolls Royce Dawn Key Fob Problems
There are very few cars that provoke the sort of gasp that the Rolls-Royce Dawn does. Even with the cloth top down it's a stunning vehicle.
It comes with all the standard devices - like motorised doors that can close at the press of a button, and umbrellas concealed in the door's opening. It also has an ultra-smooth V12 engine that is driven at a near-silent pace.
Dead Coin Battery
The most frequent reason for a key fob to not be able to lock or unlock doors is a dead coin battery. rolls royce dawn key is also among the most simple problems to fix since it is usually replaced in a few minutes. To avoid getting a faulty coin battery, make sure you choose a replacement battery with the same voltage, size and specifications as the first one. Never use a battery exposed to clean water, like rain, tap-water that is clean, or even soda, since this can damage the internal chip. If the key fob does not work after reprogramming it using an original key, visit an authorized dealer.
Other reasons that the key fob may not be working include Water Damage, Receiver Module issues, Signal Interference and a bad electronic chip.
Poor Battery Contact
The button cell battery inside the key fob for your Rolls Royce Dawn may lose its charge. It is easy to replace the battery. Be sure to only replace the battery with one of the same size and voltage. Talk to an employee at the auto parts store if are unsure what type to buy.
The corrosion on the terminals of the battery in the terminals of a Rolls Royce Dawn may also prevent it from being able to start. This is a common problem with older batteries, particularly those that haven't been charged for a long period of time. You can use a multimeter for assessing the conductivity of your battery to determine if your terminals on your battery have rust. Set the meter at ohms and touch one of its probes to the negative terminal of your Dawn. The other probe should be placed on a metal surface of the engine or chassis. The reading should be close to zero ohms.
Another sign of a weak battery in your Dawn is clicking noise when you attempt to start the engine. This is due to the accessories, the starter solenoid and the engine require low voltage while the starter solenoid demands high current.
Water Damage
Damage to your water pipes is likely to occur if you accidentally drop your Rolls Royce Dawn Key Fob in the sink or leave it in the rain. Although the electronic chip inside is protected by rubber seals prolonged exposure to clean tap water or even salty ocean water could cause it to stop working properly.
Over time water can cause rust, resulting in faulty circuitry which can cause issues with the car's security and ignition systems. It could also affect the transmission of signals, causing the remote keyless system to fail. The key fob may even lock your vehicle or activate the immobiliser system, leaving you without a vehicle.
To stop this from happening, remove the key fob and wipe it down with a damp cloth to dry any moisture that remains. You can also place the key in an airtight container with uncooked rice or silica gel packets to soak up any moisture. After the key has dried, it should function normally again. If the key does not work, it is likely that the 12 volt batteries or the receiver modules are the cause. These need to be changed.
Issues with Receiver Modules
If you've tried a new phone but the remote keyfob is still 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 vehicle's electronics. If the chip in the module is damaged, it will not be in a position to communicate with other modules inside the vehicle. You'll require a scanner to diagnose the problem. It will be able to show what the computer in the vehicle is telling it.
The metal clips that hold the battery in the key fob of your Dawn complete the circuit and keep it in position. The clips may corrode and cause the battery contacts to become ineffective. When replacing the battery, be sure 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 an electronic key fob that suddenly stopped working. The key fob may be damaged by water if dropped in water or soaked in soapy water. You can clean the key fob using electronic cleaners or isopropyl ethanol but you will have to replace the chip in case it becomes fried.
Signal Interference
Sometimes, your Dawn key fob may stop working due to signal interference. Interference can be caused due to objects near your car, weather conditions, and transmitters using the same frequency band. A defective receiver module can also cause interference. If you are unable to reduce the interference, you might be able to use a range extender or signal booster.
If the button cell battery is completely drained it's time to replace it. To ensure compatibility with your vehicle, the battery has to be the same voltage and size as the original. If your key fob is intermittently working, the chip could be fried.
If you've tried all of the above tips and still can't unlock your key or lock, it's likely time to call an experienced locksmith. A reliable locksmith will be able to assist you with any Rolls Royce key fob or key programming needs, including the reprogramming and replacement. They can give you a quote for the work required. Request the locksmith's rates and credentials prior to hiring them.
Dead 12 Volt Battery
The 12 volt battery in your Rolls Royce Dawn is responsible to provide high electrical current, not only for starting the engine but also to supply power to all accessories as well as on-board computers. If this battery is in a dead state or the flow of power to the engine is disrupted due to corrosion of the battery terminals or ground connection, all electronic components on board including the remote keyless system will stop functioning.
A multimeter can be used to check the conductivity of your Dawn battery. To do this, remove the negative cable from the battery and connect one probe of the Multimeter to the grounding wire of the battery. Then, touch the other probe of the Multimeter to any exposed metal components of your vehicle, such as the body, chassis or engine. The reading should be in the vicinity of zero Ohms.
If the results aren't satisfactory You can replace the battery with a fresh one with the same size, voltage and specification. Make sure that you fully charge the replacement battery prior to using it. The most common cause of a bad battery is internal degradation caused by the effects of aging however it could also be due to an excessive draw or if your vehicle was parked for long periods of time.
