How to Fix Rolls Royce Dawn Key Fob Problems
Few cars can elicit the kind of uncontrollable sigh that the Rolls-Royce Dawn can. Even with the cloth top down it's an amazing car.
It comes with all the standard gadgets such as motorized doors that can be shut with the touch of a button. Umbrellas are hidden in the openings of the doors. It comes with a smooth V12 engine which can be driven in complete silence.
Dead Coin Battery
A dead coin battery is the most common reason of a key fob that isn't locking or unlocking the doors. It is also among the simplest to fix because it can usually be replaced in a matter of minutes. Make sure to use a new coin battery with the same voltage, size and specifications as the first to avoid a defective battery. Also, don't use a battery that has been exposed to clean water (rain or clean tap water, or even soda) because this could damage the internal chip. If thekeylab.co.uk fob doesn't work after reprogramming it using an original key, you can visit an authorized dealer.
Other reasons the key fob might not be working are 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 may lose its charge. Replacing the battery is a simple and easy fix. Be sure you only replace it with a fresh battery that is the same size and voltage. Contact the auto parts store if aren't sure what type of battery to purchase.
The corrosion of the battery terminals of the battery terminals in a Rolls Royce Dawn can also stop it from beginning. This problem occurs with older batteries, especially if they haven’t been charged for a long amount of time. Multimeters are a good tool to test the conductivity to determine if your battery's terminals are corroded. Set the meter at ohms, and place one probe against the negative terminal of your Dawn. Then, touch the other probe to a plain metal part of the chassis or engine. The reading should be near zero ohms.
A clicking sound is another indication of an insufficient Dawn battery. This is due to the starter solenoid, accessories and the engine require low current while the starter solenoid demands high current.
Water Damage
Water damage could 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 could cause it to stop working properly.
Moisture can cause corrosion over time, which can lead to malfunctioning circuits that can cause issues with the ignition and security system of your car. It could also affect the signal transmission, leading to the malfunction of remote keyless systems. The key fob may lock your car, or activate the immobiliser, leaving you in the dark.
To avoid this occurring, take off the key fob and wipe it clean with a damp cloth to remove any remaining moisture. You can also place the key in a bag filled with uncooked silica gel or rice to absorb any moisture. Once the key is dry, it should function normally again. If not, the issue is likely to be with the 12 volt battery, or the receiver module, which will require changing the program to fix it.
Issues with Receiver Modules
If you've tried a different battery, but the remote key fob still isn't working, it might be time to replace the receiver module. The receiver module receives radio frequency signals from your key fob and converts them to commands for the car's electronic system. 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 need a scanner to diagnose the problem. It will reveal what the computer in the vehicle is telling it.
The battery inside the key fob of your Dawn has metal retaining clips that hold it in place and complete the circuit. These clips can get corroded and render the battery's contacts ineffective. When replacing the battery, ensure that it's exactly the same size and voltage as the original. Otherwise it could cause damage to the chip inside the key fob.
If the key fob stops suddenly it could be a sign that it has been damaged by water. This could happen if the key fob is dropped into water or gets wet with soapy water. You can try cleaning the key fob by using isopropyl alcohol, or electronic cleaners, but if the chip inside the key fob is damaged, you'll need to replace it.
Signal Interference
Signal interference could cause your Dawn keyfob to cease functioning. The interference could be by objects that are near your car or weather conditions, or transmitters using the same frequency band. A faulty receiver module can also cause interference. If you are unable to reduce the interference, you may be able to use an extender or signal booster.
It is crucial to replace the button cell battery inside your Dawn key fob if it's drained. To ensure compatibility with your vehicle, the battery should be the same size and voltage as the original. If your key fob begins to malfunction intermittently, it could indicate the chip is damaged.
If you've tried the previous tips and still can't unlock your key or lock, it's likely time to call a professional locksmith. A reputable locksmith can assist you with all of your Rolls Royce key fob and key programming needs. This includes reprogramming or replacement. They'll be able to give you a quote for the work required. Ask the locksmith for their rates and credentials prior to hiring them.
Dead 12 Volt Batterie
The 12 volt Battery in your Rolls Royce Dawn provides high current to start the engine, but also for all the accessories and computers onboard. If the battery is dead, or the current flow to the engine is interrupted because of corrosion on the battery's terminals or ground connection, all on-board electronics including the remote keyless system will stop working.
To determine the condition of your Dawn battery you can conduct an electrical conductivity test using a multimeter. To do this you must disconnect the negative cable from the battery, and then connect one probe of the multimeter to the ground wire of the battery, and the other probe to any exposed metal component of the vehicle's engine, chassis or body. The reading should be close to zero ohms.
If the results were not satisfactory then replace the battery with a new one with the same voltage, size and specification. Make sure that you fully charge the new battery prior to using it. The most frequent cause of the battery failing is internal degradation as a result of age. However, it can also occur as a result an unnatural draw or if your car has been left parked for a prolonged period.
