How to Fix Rolls Royce Dawn Key Fob Problems
Few cars can generate the kind of awe-inspiring gasp that the Rolls-Royce Dawn can. Even with the top-down cloth it's an amazing car.
It is equipped with all the classic gadgets - crowd-pleasers like motorised doors that can close at the press of a button, and umbrellas that are hidden inside the door's opening. It also comes with a smooth V12 engine that is driven at a near-silent pace.
Dead Coin Battery
A dead battery for a coin is the most common cause of a key fob not locking or unlocking the doors. It is also the simplest to fix since it can be replaced in several minutes. To avoid a damaged coin battery, ensure that you use a new battery that is the same size, voltage and specifications as the first one. Don't expose a battery to clean water, such as rain, tap-water that is clean, or even soda, as this can damage the internal chip. If the key fob does not work after reprogramming it with an original key, you can visit an authorized dealer.
Other reasons the key fob may not be working include water damage, receiver Module Issues, Signal Interference or a bad electronic chip.
Poor Battery Contact
The button cell battery in the key fob of your Rolls Royce Dawn can lose its charge and stop functioning. Replacing the battery is a fast and simple fix. Be sure to only replace the battery with one that is the same size and voltage. Ask rolls royce phantom key fob thekeylab.co.uk at the auto parts store if you are unsure what type to purchase.
The corrosion on the terminals of the battery in a Rolls Royce Dawn may also hinder it from starting. This is a problem that is seen in older batteries, particularly when they haven't been charged for a long amount of time. Multimeters are a good tool for checking the conductivity to determine if your battery's terminals are corroded. 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 metal part of the chassis or engine. The reading should be near zero ohms.
A clicking sound is another sign of a weak Dawn battery. This is due to the fact that the starter solenoid as well as other components require a high amount of electric current while the engine requires low current to operate. This means that the battery will not be able to supply enough charge.
Water Damage
If you dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it's likely damaged by water. The chip's electronic components are protected by rubber seals but prolonged exposure to clean water or salty ocean water can cause it to cease functioning.
Moisture can cause corrosion over time, leading to malfunctioning circuits, which can lead problems with the ignition and security system of your vehicle. It can also interfere in the signal transmission, leading to the failure of remote keyless systems. The key fob may even unlock your vehicle or activate the immobiliser system, leaving you in a bind.
To stop this from occurring, take off the key fob and wipe it down with a damp cloth to dry out any moisture that remains. You can also place the key in an airtight container with uncooked rice or silica gel packets to absorb any residual moisture. Once dry, the key should work normally again. If not, the problem is most likely due to the 12 volt battery or the receiver module, which requires changing the program to fix it.
Receiver Module Issues
If you have tried a new cell and the remote keyfob still does not function, then it may be time to replace the receiver module. This is the part 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 within the vehicle. To diagnose the problem you'll require an OBD scanner to show you what the on-board computer is telling it to do.
The metal clips that secure the battery in the key fob that you use for your Dawn complete the circuit and keep it in the right place. These clips can corrode and render the battery contacts ineffective. If you are replacing the battery, make sure it's an exact match in size and voltage to the previous one. It could damage the chip in the key fob.
If the key fob stopped suddenly, it could be an indication that it was damaged by water. The key fob can be damaged by water if it is dropped into water or immersed in soapy water. You can clean the key fob using electronic cleaners or isopropyl alcohol, but you will need to replace the chip in case it becomes fried.
Signal Interference
Occasionally your Dawn key fob might not function due to signal interference. The interference could be by objects that are near your vehicle, weather conditions, and transmitters using the same frequency band. A malfunctioning receiver module could also cause interference. If you are not able to eliminate the interference, you might consider using a range extender or signal booster.
If the battery for the button cell is completely drained 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 begins to malfunction intermittently, it may indicate the chip is damaged.
If you have tried everything above but your key is still unable to unlock or lock, it's time for a locksmith. A reputable locksmith will be able to help you with any Rolls Royce key fob or key programming needs, such as reprogramming and replacement. They will be able to offer a quote for the work that is required. Be sure to inquire with the locksmith about their rates and credentials before hiring them.
Dead 12 Volt Batterie
The 12 volt battery inside your Rolls Royce Dawn provides high current to start the engine as well as for all onboard computers and accessories. The battery will not function in the event of a dead battery or if the flow of electricity is interrupted by corrosion on the terminals of the battery or the ground connection.
To determine the condition of your Dawn battery, you can perform the test of conductivity using a multimeter. To do this, remove the negative cable from the battery, and then connect one probe of the Multimeter to the ground 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 close to zero ohms.
If the results aren't satisfactory If the results are not satisfactory, you can replace the battery with another one with the same size, voltage and specification. Make sure that the new battery is fully charged prior to use it. The most frequent cause of the battery failing is internal degeneration due to the aging process. However, it can be caused by parasitic draw or if your car has been parked for a long time.
