How to Fix rolls royce smart key Royce Dawn Key Fob Problems

There aren't many automobiles that can generate the kind of involuntary gasp that the Rolls-Royce Dawn does. Even with the top of the cloth down it's a stunning vehicle.

It is packed with all the typical gadgets and features, including motorised doors that can be closed with the touch of one button. Umbrellas are hidden in the door's openings. It is equipped with a smooth V12 engine which can be driven in near silence.

Dead Coin Battery

The most common reason for a key fob to not unlock or lock the doors is a dead battery. It is also the most simple to fix since it can be replaced in only a few moments. Use a new coin battery that is the same size, voltage, and specifications as the original to avoid a damaged battery. Also, do not use batteries that have been exposed to clean water (rain, clean tap water, or even soda) as this may harm the internal chip. If the key fob won't work after reprogramming it using an original key, you can visit an authorized dealer.

Other reasons why the key fob may not be functioning include water damage, receiver Module Issues, Signal Interference or a bad electronic chip.

Poor Battery Contact

The button cell battery on the key fob for your rolls royce phantom key Royce Dawn may lose its charge. Replacing the battery is a simple and easy fix. However, make sure that you only replace it with a fresh battery with the same voltage and size. If you're not sure what type of battery to buy, you can try asking someone at your local auto parts store.

The corrosion on the battery terminals of the terminals of a Rolls Royce Dawn may also stop it from starting. This is a typical issue with older batteries, particularly those that haven't been charged for a long time. Multimeters are a good tool for assessing the conductivity of your battery to determine if your battery terminals have corrosion. Set the meter at the ohms scale, and then place one probe against the negative terminal of your Dawn. The other probe should be placed on a bare metal surface of the chassis or engine. The reading should be near zero ohms.

A clicking sound is another indication of weak Dawn battery. This is due to the starter solenoid, the accessories and the engine require low current while the starter solenoid demands high current.

Water Damage

If you accidentally dropped your Rolls Royce Dawn key fob in the sink or left it sitting in the rain, it's probably to be suffering from water damage. The electronic chip is protected by rubber seals but prolonged exposure to clean water or salty ocean water could cause it to stop functioning.

Over time, moisture can cause rust, resulting in faulty circuitry that can lead to problems with the car's security and ignition systems. It can also interfere in the signal transmission, leading to the malfunction of remote keyless systems. The key fob could disable your car or activate the immobiliser, leaving you in the dark.

To prevent this from happening, remove the key fob from its case and wipe it with the help of a damp towel to get rid of any moisture. You can also put the key in an airtight container with uncooked silica gel or rice packets to help 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 responsible for the problem. These need to be reprogrammed.

Receiver Module Issues

If you've tried a new battery but the remote key fob doesn't work, it may be time to replace the receiver module. The receiver module receives radio frequency signals from your key fob and converts them into commands for the car's electronic system. If the chip in the module is damaged the module won't be able to communicate with other modules of the vehicle. To identify the issue you'll require an OBD scanner that can determine what the on-board computer is telling it to do.

The battery in the key fob of your Dawn has metal clips that hold it in place and complete the circuit. The clips may corrode and render the battery's contact ineffective. When replacing the battery, make sure that it's the exact same size and voltage as the original. Otherwise, it could damage the chip inside the key fob.

Water damage could be the cause for an electronic key fob that suddenly stopped working. This could happen if the key fob is dropped in water or is soaked by soapy water. It is possible to clean the key fob using isopropyl alcohol or other electronic cleaners, but if the chip in the key fob is damaged you'll have to replace it.

Signal Interference

Occasionally your Dawn key fob may not function due to signal interference. Interference could be caused by objects within the vicinity of your car or weather conditions, as well as transmitters operating on the same frequency band. Interference can result from a defective receiver module. If you can't resolve your problem by reducing the amount of interference, you could try using an amplifier for signal or a range extender.

If the button cell battery is completely depleted it's time to replace it. The battery should be the same size, voltage and type as the original battery to ensure that your vehicle is compatible with the key fob. If your key fob starts to malfunction intermittently, it could mean the chip is fried.

If you have tried all of the above, but your key is still unable to unlock or lock, then it's time for an expert locksmith. A reputable locksmith will be able assist you with any Rolls Royce key fob or key programming needs, such as reprogramming and replacement. They can give you a quote for the work that is required. Be sure to ask the locksmith about their rates and credentials prior to hiring them.

Dead 12 Volt Batterie

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 provide power to all accessories and on-board computers. If the battery is in a dead state or the flow of power to the engine is disrupted because of corrosion on the battery terminals or ground connection, all electronics onboard including the remote keyless system will stop working.

You can use a multimeter to check the conductivity of your Dawn battery. To do this, disconnect the negative cable from the battery and then touch one probe of the multimeter to the ground wire of the battery, and the other probe to any exposed metal part of your vehicle's engine chassis or body. The reading should be near zero ohms.

If the results are not satisfactory then replace the battery with an alternative battery that has the same size, voltage and specifications. Make sure you fully charge the new battery before using it. A common cause of an unsatisfactory battery is internal degradation resulting from the aging process, but it can be caused by an excessive draw or if the car is in a garage for a long period of time.
