The most common reason for a key fob that does not unlock or lock the doors is a dead battery. It is also one of the simplest to fix because it can usually be replaced in a few minutes. You should use a brand new coin battery with the same size, voltage, and specification as the original to avoid a faulty battery.

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

Receiver Module Issues

If you've tried a new cell and the remote keyfob is still not work, then it might be time to replace your receiver module. This is the component that receives the radio frequency signals from the key fob, and converts them into commands for your car's electronics. If the chip in the module is damaged the module won't be able to communicate with other modules of the vehicle. To diagnose the problem you'll need an OBD scanner to determine what the on-board computer is telling it to do.

The metal clips that hold the battery in the key fob that you use for your Dawn complete the circuit and keep it in the right place. The clips may corrode and render the battery contacts ineffective. If you replace the battery, make sure it's the exact size and voltage to the previous one. Otherwise it could cause damage to the chip inside the key fob.

Signal Interference

Occasionally, your Dawn key fob may stop working due to signal interference. The interference could be by objects in the vicinity of your car or weather conditions, or transmitters using the same frequency band. A defective receiver module can also cause interference. If you are unable to resolve your issue by cutting down on the amount of interference, try using a signal booster or range extender.

It is essential to replace the button cell battery on your Dawn key fob in the event that it's drained. The battery must be the same voltage, size and type as the original battery to ensure that your vehicle remains compatible with the key fob.

Dead 12 Volt Battery

The 12 volt battery in your Rolls Royce Dawn is responsible for providing high electric current, not just to start the engine, but also to provide power to all accessories and on-board computers. If this battery is in a dead state 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 functioning.

You can use a multimeter to test the conductivity of your Dawn battery. 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 the vehicle's engine, chassis or body. The reading should be near zero Ohms.

If the results weren't satisfactory then replace the battery with another battery with the same size, voltage and specification. Be sure to fully charge the new battery before using it. The most common cause of a bad battery is internal degradation resulting from the effects of aging but it can also be due to parasitic draw, or if the vehicle is for a long time.
