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 the most simple to fix as it can be replaced in only a few minutes. To avoid the possibility of a defective coin battery, always make sure you use a new battery that is the same size, voltage and specifications as the original one. Also, don't use a battery that has been exposed to clean water (rain or clean tap water or even soda) since this can damage the internal chip. If the key fob still isn't working, try reprogramming the key with an original key, or visit an authorized dealer.

Corrosion on the battery terminals in the battery terminals in a Rolls Royce Dawn can also hinder the battery from starting. This issue occurs with older batteries, particularly if they haven’t been charged for a prolonged period of time. To determine if your battery's terminals aren't corroded you can utilize a multimeter to test the conductivity. Set the meter to ohms, and connect one probe to the negative terminal in your Dawn. Then, connect rolls royce ghost key www.thekeylab.co.uk to a plain metal part of the engine or chassis. The reading should be close to zero ohms.
A clicking noise is another indicator of an insufficient Dawn battery. This is due to the accessories, the starter solenoid and the engine require low current while the starter solenoid requires high current.
Water Damage
If you accidentally dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it's likely suffering from water damage. The chip's electronic components are protected by rubber seals but prolonged exposure to sea salt or clean water can cause it to stop functioning.

Issues with the Receiver Module
If you've tried a different battery, but the remote key fob still isn't working, it could be time to replace the receiver module. This is the component that receives the radio frequency signals from the key fob and converts them into commands for the car's electronics. If the chip inside the module is damaged the module won't be able to communicate with other modules of the vehicle. You'll need a scanner in order to identify the issue. It will reveal what the computer in the vehicle is telling it.

Interference can be caused by objects within the vicinity of your vehicle or by weather conditions, or transmitters operating on the same frequency band. Interference can be caused by a malfunctioning receiver module. If you are not able to eliminate the interference, you may consider using an extender of range or signal booster.
If the battery for the button cell is completely drained, 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. If your key fob has stopped working, the chip may be fried.

To test the condition of your Dawn battery, you can perform a conductivity test with a multimeter. To do this, 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 your vehicle's engine body or chassis. The reading should be near zero in ohms.
