How to Fix Rolls Royce Dawn Key Fob Problems

There are very few cars that provoke the sort of involuntary gasp the Rolls-Royce Dawn does. Even with the top-down cloth it's an amazing car.

It is packed with all the standard devices and features, including motorised doors that can be shut at the push of the button. Umbrellas are hidden in the door's openings. It also comes with a smooth V12 engine that can be driven at a near-silent pace.

Dead Coin Battery

The most frequent reason for a key fob to not lock or unlock the doors is a dead battery. It's also one of the easiest to fix as it can usually be replaced in just a few minutes. You should use a brand new coin battery that has the same voltage, size and specifications as the original to avoid a faulty battery. Don't expose a battery to pure water, such as rain, clean tap-water or even soda, because this can damage the internal chip. If the key fob doesn't work you can try reprogramming it with an original key, or visit an authorized dealer.

This is a typical issue with older batteries, particularly those that haven't been charged for a long period of period of. To check if your battery terminals are corrosion free, you can utilize a multimeter to test the conductivity. Set the meter to ohms, and place one of the probes against the negative terminal of your Dawn. Touch the other probe on a metal surface of the chassis or engine. rolls royce phantom key should be close to zero ohms.


Another indication of a weak battery in your Dawn is clicking noise when you try to start the engine. This is due to the accessories, the starter solenoid and the engine require low current while the starter solenoid demands high current.

Water Damage

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

You can also place the key in a bag with uncooked silica gel or rice to absorb any moisture. After drying the key should function normally again. If not, the problem is likely to be with the 12 volt battery, or the receiver module, which will require reprogramming to fix.

Receiver Module Issues

If you've already tried a new battery but the remote key fob still isn't working, it might be time to replace the receiver module. This is the component that receives radio frequency signals from the key fob and transforms them into commands for your car's electronic. If the chip inside the module is damaged the module won't be able communicate with the other modules of the vehicle. You'll require a scanner to determine the issue. It will show you what the computer on the vehicle is telling it.

These clips are susceptible to corroding and render the battery contacts ineffective. When replacing the battery, be sure that it's the exact same size and voltage as the original. It could damage the chip in the key fob.

If the key fob stopped suddenly it could be a sign that it was damaged by water. This can happen when 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 ethanol, but you will need to replace the chip if it's fried.

Signal Interference

Interference can be caused by objects that are near your vehicle or weather conditions, or transmitters using the same frequency band. The interference can be caused by a malfunctioning receiver module. If you're unable to cut down on interference, you might want to try using an extender of range or signal booster.

If the button cell battery is completely drained then it's time to replace it. The battery should have the same voltage, size and type as the original battery to ensure your vehicle remains compatible with the key fob.

Dead 12 Volt Battery

The 12 volt battery in your Rolls Royce Dawn is responsible for supplying high electric current not only to start the engine, but also to power all accessories and on-board computers. This battery will not work when it is not working or if the flow of electricity is interrupted by corrosion of the battery's terminals or the ground connection.

You can use a multimeter to determine the conductivity of your Dawn battery. To accomplish this you must disconnect the negative cable from the battery and then apply 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 in ohms.

If the results are not satisfactory, replace the battery by a new one with the same voltage, size and specification. Make sure that the new battery is fully charged before you use it.
