Dead Coin Battery

A dead coin battery is the most common reason of a key fob not locking or unlocking the doors. It's also one of the simplest to fix because it is usually replaced in just a few minutes. To avoid getting a faulty coin battery, make sure you use a new battery that has the same size, voltage and specifications as the original one. Never use a battery exposed to clean water, like rain, tap-water that is clean, or even soda, as this can damage the internal chip. If the key fob doesn't work after reprogramming it with an original key, you can go to an authorized dealer.

This is a common problem with older batteries, particularly those that haven't been charged in a long time. To ensure that your battery's terminals are corrosion free, you can use a multimeter to check the conductivity. Set the meter to ohms and touch one of its probes to the negative terminal in your Dawn. Place the other probe on a metal surface of the chassis or engine. The reading should be near zero ohms.

Another indication of a weak battery in your Dawn is a clicking sound when you try to start the engine. This is due to the starter solenoid, the accessories and the engine require low current while the starter solenoid needs high current.

Water Damage

If you accidentally dropped your Rolls Royce Dawn key fob in the sink or left it in the rain, it is likely to be suffering from water damage. Although the electronic chip inside is protected by rubber seals, prolonged exposure to pure tap water or salty ocean water could cause it to cease functioning properly.

If not, the issue is most likely with the 12 volt battery, or the receiver module, which will require reconfiguring to fix the issue.

Receiver Module Issues

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

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 electronic components on board including the remote keyless system will stop working.
