The most common reason for a key fob that does not lock or unlock the doors is a dead battery. It is also the simplest to repair as it can be replaced in only several minutes. To avoid the possibility of a defective coin battery, always make sure you use a new battery with the same size, voltage and specifications as the first one.

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 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 on your Dawn. Then, connect the second probe to a metal part of the chassis or engine. The reading should be near zero ohms.

A click is another sign of weak Dawn battery. This is due to the fact that the starter solenoid and other accessories require high currents of electricity, while the engine needs a low current to function. This means that the battery cannot provide enough charge.

Receiver Module Issues

If you've already tried a new battery but the remote key fob isn't working, it might be time to replace the receiver module.

If the chip in the module is damaged it will not be able communicate with the other modules of the vehicle. To determine the cause you'll require an OBD scanner that can show you what the on-board computer is telling it to do.

The battery inside the key fob of your Dawn has metal retaining clips that keep it in place and complete the circuit. The clips may corrode and render the battery's contacts ineffective. If you decide to replace the battery, ensure that it's an exact match in size and voltage to the previous one. It could cause damage to the chip inside the key fob.

If the key fob stopped working abruptly, it could indicate that it has been damaged by water. This could happen if the key fob is dropped in water or gets wet with soapy water.

Interference can be caused due to objects near your vehicle or weather conditions, as well as transmitters that operate on the same frequency band. It could also be caused by a faulty receiver module. If you are unable to resolve your problem by reducing the amount of interference, you could try using an amplifier or range extender.

If the battery for the button cell is completely drained, it's time to replace it. The battery should have the same size, voltage and type as the original battery to ensure that your vehicle is compatible with the key fob. If your key fob begins to work intermittently, it could mean the chip is fried.

Dead 12 Volt Battery

The 12 volt battery inside your Rolls Royce Dawn provides high current to start the engine as well as for all onboard computers and accessories. The battery won't work in the event of a dead battery or if the flow of current is interrupted by corrosion of the terminals of the battery or the ground connection.

To determine the condition of your Dawn battery it is possible to conduct a conductivity test with a multimeter. To perform this test you must disconnect the negative cable from the battery and then touch 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 zero ohms or close to it.
