How to Fix Rolls Royce Dawn Key Fob Problems

Few cars can create the kind of awe-inspiring gasp that the rolls royce wraith key fob-Royce Dawn can. Even with the cloth top down it's an amazing car.

It comes with all the typical features such as motorized doors that can be shut at the push of the button. Umbrellas are concealed within the openings of the doors. It also has a smooth V12 engine that is driven with a whisper.

Dead Coin Battery

The most common reason for a key fob to not lock or unlock the doors is a dead coin battery. It is also among the most simple problems to fix since it can be replaced in a few minutes. You should use a brand new coin battery that has the same voltage, size, and specifications as the first to avoid a faulty battery. Never use a battery exposed to pure water, such as rain, clean tap-water, or even soda, since this can damage the internal chip. If the key fob doesn't work after reprogramming it using an original key, you can visit an authorized dealer.

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

Poor Battery Contact

The button cell battery in the key fob of your Rolls Royce Dawn can lose its charge and cease functioning. Replacing the battery is a quick and easy fix. Be sure to only replace the battery with one that is the same size and voltage. Contact the auto parts store if you are not sure which type to buy.

Corrosion on the battery terminals in the battery terminals in a Rolls Royce Dawn can also hinder the battery from starting. This is a problem that is common with older batteries, particularly if they haven’t been charged for a long period of time. You can use a multimeter to test the conductivity to determine if your battery's terminals are corroded. Set the meter on the ohms scale, and then place one probe against the negative terminal of your Dawn. Then, touch the other probe to a metal part of the chassis or engine. The reading should be close to zero ohms.

Another indication of a weak battery in your Dawn is the sound that you hear when you try to start the engine. This is because starter solenoid, the accessories and the engine require low voltage while the starter solenoid demands high current.

Water Damage

Water damage is likely to occur if you accidentally drop your Rolls Royce Dawn Key Fob in the sink or leave it in the rain. While the chip inside is protected by rubber seals prolonged exposure to clean tap water or salty ocean water may cause it to stop working properly.

Over time water can cause corrosion, which results in faulty circuitry that can result in problems with the car's security and ignition systems. It can also interfere with the transmission of signals, causing the remote keyless system to fail. The key fob may even disable your vehicle or activate the immobiliser system, leaving you stranded.

To stop this from to happen, remove the key fob and wipe it with a damp cloth to dry out any moisture that remains. You can also put the key in a bag that is airtight with uncooked rice or silica gel packets to to absorb any moisture that remains. After drying the key should function 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 phone but the remote key fob does not work, then it might be time to replace your receiver module. This is the component that receives radio frequency signals from the key fob and transforms them into commands for the car's electronics. If the chip in the module is damaged, it won't be able to communicate with other modules in the vehicle. To diagnose the problem you'll require an OBD scanner that will show you what the on-board computer is telling it to do.

The metal clips that hold the battery in the key fob for your Dawn complete the circuit and keep it in position. These clips can get corroded and render the battery's contact ineffective. If you decide to replace the battery, ensure that it's a perfect match in size and voltage to the original one. It could cause damage to the chip inside the key fob.

Water damage could be the cause for a key fob that suddenly stopped working. This could happen if the key fob is dropped in water or gets wet with soapy water. It is possible to clean the keyfob by using electronic cleaners or isopropyl alcohol, but you will need to replace the chip in case it becomes fried.

Signal Interference

Signal interference could cause your Dawn keyfob to cease functioning. Interference can be caused by objects that are within the vicinity of your vehicle, weather conditions and transmitters that operate on the same frequency band. A faulty receiver module can also cause interference. If you can't resolve your issue by decreasing the amount of interference, try using an amplifier for signal or a range extender.

It is crucial to replace the button cell battery on your Dawn key fob if it's drained. To ensure compatibility with your vehicle, the battery should have the same size and voltage as the original. If your key fob starts to fail intermittently, it could indicate the chip is damaged.

If you've tried everything above but your key doesn't seem to be unlocking or lock, then it's time for a locksmith. A reputable locksmith will assist you with all of your Rolls Royce key fob and key programming needs. This includes reprogramming and replacement. They will be able to provide you with a price estimate for the work that is needed. You can ask the locksmith for their rates and credentials prior to hiring them.

Dead 12 Volt Battery

The 12 volt battery in your Rolls Royce Dawn is responsible for providing high electrical current, not only to start 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 current to the engine is interrupted due to corrosion of the battery's terminals or ground connection, all on-board electronics including the remote keyless system will cease to function.

To check the condition of your Dawn battery, you can perform an electrical conductivity test using a multimeter. To do this, remove the negative cable from the battery, and then 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 components of your vehicle, such as the chassis, body, or engine. The reading should be near zero in ohms.

If the results weren't satisfactory you can replace the battery with an alternative battery that has the same size, voltage, and specification. Make sure that the new battery is fully charged prior to use it. The most common cause of an unreliable battery is internal degradation due to age. However, it could be caused by an unnatural draw or if your vehicle has been parked for a long time.
