Dead Coin Battery

The most common reason for a key fob to not unlock or lock the doors is a dead battery. It is also the easiest to repair as it can be replaced in a few minutes. Make sure to use a new coin battery that has the same voltage, size and specifications as the first to avoid a damaged battery. Do not expose a battery to clean water, like rain, clean tap water or even soda, because this could damage the internal chip. If the key fob won't work after reprogramming it using an original key, you can visit an authorized dealer.

This issue is common with older batteries, particularly when they haven't been charged for a long period of time. You can use a multimeter to test the conductivity to see if your battery's terminals are corroded. Set the meter to ohms and connect one probe to the negative terminal on your Dawn. Then, touch the other probe to a plain metal part of the engine or chassis. The reading should be close to zero ohms.

Another indication of a weak battery in your Dawn is a clicking sound when you attempt to start the engine. This is due to the fact that the starter solenoid as well as other components require high currents of electricity, while the engine requires a lower current to operate. This means that the battery is unable to supply enough charge.

You can also put the key in an airtight bag with uncooked silica gel or rice packets to help to absorb any moisture that remains. After the key has dried it should function normally again. If the key doesn't function, it is possible that the 12 volt batteries or receiver modules are at fault. These need to be replaced.

Issues with the Receiver Module

If you have tried a new cell and the remote key fob does not function, then it may be time to replace your receiver module. This component 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 won't be in a position to communicate with other modules within the vehicle. To identify the issue, you'll need an OBD scanner to determine what the on-board computer is telling it to do.

The battery inside the key fob of your Dawn has metal clips that keep it in place and complete the circuit. These clips can get corroded and make the battery's contacts ineffective. When replacing the battery, ensure that it is the exact same size and voltage as the original. Otherwise, it could damage the chip inside the key fob.

Water damage may be the reason behind a key fob that suddenly stopped working. The key fob can be damaged by water if it is dropped into water or soaked in soapy water. It is possible to clean the key fob by using isopropyl alcohol or electronic cleaners, but if you find that the chip inside the key fob is damaged, you'll need to replace it.

Signal Interference

Occasionally your Dawn key fob will cease to function due to signal interference. The interference could be by objects that are near your car or weather conditions, or transmitters operating on the same frequency band. A malfunctioning receiver module could also cause interference. If you are not able to cut down on interference, you might consider using a range extender or signal booster.

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

If you've tried the above methods but are still unable to get your key to open or lock, it's time to contact an experienced locksmith.

Dead 12 Volt Battery

The 12 volt battery in your Rolls Royce Dawn is responsible to provide high electrical current, not only for starting the engine but also to supply power to all accessories as well as on-board computers. If the battery is dead or the flow of current to the engine is disrupted because of corrosion on the battery's terminals or ground connection, all electronics onboard including the remote keyless system will stop working.

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

If the results were not satisfactory then replace the battery with another battery with the same voltage, size and specifications. Make sure you fully charge the replacement battery before using it. The most common reason for the battery failing is internal degradation due to the aging process. However, it could be caused by the draw of a parasite or if your vehicle has been left parked for a prolonged period.
