Dead Coin Battery

The most common reason for a key fob to not lock or unlock the doors is a dead battery. It is also the most simple to fix since it can be replaced in just a few moments. To avoid the possibility of a defective coin battery, make sure you make sure you use a new battery that has identical in size, voltage and specifications as the original one. Also, do not use batteries that have been exposed to clean water (rain, clean tap water, or soda) since this can cause damage to the internal chip. If the key fob does not function after reprogramming it using an original key, you can go to an authorized dealer.

This is a frequent issue in older batteries, especially when they haven't been recharged for a long period of time. A multimeter can be used to test the conductivity to determine if the terminals on your battery have rust. Set the meter at ohms and touch one of its probes to the negative terminal in 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 click is another indicator of a weak Dawn battery. This is due to the fact that the starter solenoid as well as other components require high electric current, while the engine requires low current to function. This means that the battery cannot provide enough charge.

Water Damage

If you accidentally dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it's probably suffering from water damage. The electronic chip is protected by rubber sealings but prolonged exposure to sea salt or clean water can cause it to stop working.

Receiver Module Issues

If you've tried a new battery but the remote key fob still doesn't work, it may be time to replace the receiver module. This is the part that receives the radio frequency signals from the key fob and converts them into commands for the car's electronics. If the chip in the module is damaged it will not be able to communicate with other modules of the vehicle. You'll need a scanner in order to diagnose the problem. It will show you what the computer in the vehicle is telling it.

The clips made of metal that hold the battery in the key fob of your Dawn complete the circuit and keep it in the right place. These clips are susceptible to corroding and make the battery's contacts ineffective. When replacing the battery, make sure that it is the exact same size and voltage as the original. Otherwise it could damage the chip inside the key fob.

If the key fob stopped working abruptly, it could indicate that it has been damaged by water. The key fob may be damaged by water if it is dropped in water or soaked in soapy water.

Interference can be caused by objects in the vicinity of your car, weather conditions and transmitters that operate on the same frequency band. A malfunctioning receiver module could also cause interference. If you are unable to resolve your issue by cutting down on the amount of interference, try using an amplifier or range extender.

It's important to replace the button cell battery on your Dawn key fob if it's depleted. The battery should be the same voltage, size and type as the original battery to ensure that your vehicle is compatible with the key fob. If your key fob has stopped functioning, the chip could be fried.

If you've tried all the above and your key doesn't seem to be unlocking or lock, then it's time to call an expert locksmith.

If the battery is dead or the flow of current to the engine is disrupted because of corrosion on the battery terminals or ground connection, all on-board electronics including the remote keyless system will stop working.

To determine the condition of your Dawn battery it is possible to conduct an electrical conductivity test using a multimeter. To do this remove 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 your vehicle's engine, chassis or body. The reading should be zero ohms or close to it.
