Dead Coin Battery

The most frequent reason for a key fob to not be able to lock or unlock doors is a dead battery. It is also the most simple to repair as it can be replaced in only several minutes. You should use a brand new coin battery with the same voltage, size and specifications as the original to avoid a defective battery. Don't expose a battery to clean water, such as rain, clean tap water, or even soda, since this could damage the internal chip. If the key fob still isn't working try reprogramming the key using the original key or visit an authorized dealer.

This issue occurs with older batteries, particularly when they haven't been charged for a long period of time. To check if your battery terminals aren't corroded you can utilize a multimeter to test the conductivity. Set the meter to ohms, and touch one of its probes 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 clicking noise when you attempt to start the engine. This is due to the fact that the starter solenoid and accessories require a high amount of electric current while the engine requires a lower current to work - this means that the battery will not be able to supply enough charge.

Water Damage

If you dropped your Rolls Royce Dawn key fob in the sink or left it sitting in the rain, it's likely to be suffering from water damage. The chip's electronic circuit is protected by rubber seals but prolonged exposure to clean water or salty ocean water could cause it to stop functioning.

To diagnose the problem you'll require an OBD scanner that will 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 replace the battery, ensure that it's the exact size and voltage to the original one. It could cause damage to the chip inside the key fob.

If the key fob stops working abruptly it could be an indication that it was damaged by water. This can happen when the key fob is dropped into water or is soaked by soapy water. It is possible to clean the keyfob by using electronic cleaners or isopropyl ethanol but you will have to replace the chip if it's damaged.

Signal Interference

Signal interference can cause your Dawn keyfob to cease functioning. Interference could be by objects in the vicinity of your car, weather conditions, and transmitters operating on the same frequency band. The interference can result from a defective receiver module. If you are unable to resolve your problem by reducing the amount of interference, you could try using a signal booster or range extender.

It is essential to replace the button cell battery inside your Dawn key fob in the event that it is drained. To ensure compatibility with your vehicle, the battery should have the same size and voltage as the original. If your key fob is intermittently functioning, the chip could be damaged.
