How to Fix Rolls Royce Dawn Key Fob Problems

There aren't many vehicles that generate the kind of involuntary gasp the rolls-royce phantom key price Dawn does. Even with the cloth roof off, it's a stunning car.

It has all the hallmark features - such as motorised doors that shut at the press of a button and umbrellas concealed in the door's opening. It also comes with an ultra-smooth V12 engine that is driven at a near-silent pace.

Dead Coin Battery

The most common reason for a key fob to not be able to lock or unlock doors is a dead coin battery. It is also among the easiest to fix as it can usually be replaced in a few minutes. Make sure to use a new coin battery with the same voltage, size, and specifications as the original to avoid a defective battery. Do not expose a battery to clean water, like rain, tap-water that is clean, or even soda, as it could cause damage to the internal chip. If the key fob won't function after reprogramming it using an original key, you can go to an authorized dealer.

Other reasons why the key fob might not be working are water damage, receiver Module Issues, Signal Interference and a bad electronic chip.

Poor Battery Contact

The button cell battery in the key fob of your Rolls Royce Dawn may lose its charge. It is simple to replace the battery. Make sure you replace the battery with one that is the same size and voltage. Ask an employee at the auto parts store if you are not sure which type to purchase.

The corrosion of the battery terminals in a Rolls Royce Dawn can also prevent it from starting. This is a problem that is seen in older batteries, especially in the event that they haven't been fully charged for a prolonged period of time. Multimeters are a good tool for checking the conductivity to determine if the battery's terminals are corroded. Set the meter to ohms, and connect one probe to the negative terminal of your Dawn. Then, you can connect the other probe to a bare metal part of the engine or chassis. The reading should be close to zero ohms.

A clicking noise is another sign of a weak Dawn battery. This is because starter solenoid, accessories and the engine require low current while the starter solenoid demands high current.

Water Damage

If you've accidentally dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it is likely damaged by water. The electronic chip is protected by rubber sealings but prolonged exposure to sea salt or clean water can cause it to stop functioning.

Moisture can cause corrosion over time, which can lead to malfunctioning circuitry that can cause issues with the security and ignition system of your car. It can also interfere in the transmission of signals, leading to the malfunction of remote keyless systems. The key fob can lock your vehicle or activate the immobiliser system, leaving you without a vehicle.

To prevent this from happening, remove the key fob from its case and wipe it clean with a a damp towel to remove any moisture. You can also place the key in a bag containing uncooked silica gel or rice to absorb any moisture. Once dry, the key should work normally again. If not, the issue is most likely with the 12 volt battery or the receiver module, which will require changing the program to fix it.

Receiver Module Issues

If you've already tried a new battery but the remote key fob isn't working, 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 electronic. If the chip in the module is damaged, it will not be in a position to communicate with other modules in the vehicle. To diagnose the problem, you'll need an OBD scanner that will 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 are susceptible to corroding and render the battery's contacts ineffective. When replacing the battery, be sure that it is the exact same size and voltage as the original. It could cause damage to the chip inside the key fob.

Water damage could be the cause for the key fob suddenly stopped working. This can happen when the key fob is dropped into water or is soaked by soapy water. You can clean the key fob using electronic cleaners or isopropyl alcohol, but you will need to replace the chip if it is damaged.

Signal Interference

Occasionally, your Dawn key fob might cease to function due to signal interference. Interference can be caused by objects within the vicinity of your car or by weather conditions, or transmitters on the same frequency band. A faulty receiver module can also cause interference. If you are unable to resolve your issue by reducing the amount of interference, you could try using an amplifier or range extender.

It is essential to replace the button cell battery in your Dawn key fob in the event that it is drained. To ensure compatibility with your vehicle, the battery should have the same voltage and size as the original. If your key fob starts to malfunction intermittently, it could indicate that the chip has gone out of service.

If you have tried everything above but your key doesn't seem to be unlocking or lock, then it's time to contact a locksmith. A reputable locksmith will assist you with all of your Rolls Royce key fob and key programming requirements. This includes reprogramming or replacement. They'll be able to provide you with a price estimate for the work needed. Be sure to inquire with the locksmith about their fees and credentials before hiring them.

Dead 12 Volt Battery

The 12 volt Battery in your Rolls Royce Dawn provides high current to start the engine and also for all onboard computers and accessories. The battery won't work if it is dead or if the flow of electricity is interrupted by corrosion of the terminals of the battery or the ground connection.

To check the condition of your Dawn battery, you can perform an electrical conductivity test using a multimeter. To test this, you must 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 components of your vehicle, like the chassis, body, or engine. The reading should be zero ohms or near it.

If the results aren't satisfactory, you can replace the battery with a fresh one with the same voltage, size and specifications. Be sure to fully charge the new battery prior to using it. A common cause for a bad battery is internal degradation caused by the aging process however it could also be due to parasitic draw, or if the car has been left parked for long periods of time.
