If a key fob ceases functioning the first thing to check is the battery. A drained coin battery is the most frequent reason for the key fob not to be functioning. It is crucial to replace the battery with a button battery with the same voltage, size and specifications as the original. It is also recommended to keep the key fob in a secure place and away from any objects that could cause mechanical damage, such as keys or coins.
After you replace the battery, ensure that all metal retaining clip are in place and do not cause any contact issues. Make sure the battery is clean and free of corrosive substances. If the battery isn't genuine replacement for the Rolls-Royce it may be damaged by defective components and could cause the receiver module to malfunction or even cause the doors to lock.
Faulty Receiver Module
If the key fob has stopped working after a few days and you have tried everything (replaced coin battery, reprogrammed key or even an extra) this could indicate an issue with the receiver module, which is responsible for decoding and receiving the remote control signals. This is particularly the case if you're in a position to use the key fob on another vehicle and it works.
The receivers inside the key fobs feature clips made of metal that hold the battery in place and complete the circuit when the buttons are turned on. If they're bent or damaged it can hinder the key fob from receiving the right signal to unlock/lock the car. In some cases the receiver module may also stop functioning due to a faulty electronic chip.

This results in the button to lose contact with the button and its designated pressure points, causing it to stop working properly. This is a simple fix for the majority of key fobs that can be done at home by taking the key apart, removing the buttons and cleaning them. Soldering them back to their original position can restore functionality.
Other reasons for a faulty keyfob include a dead 12 volts battery keys that aren't connected and require to be programmed again, or a malfunctioning chip. A malfunctioning electronic chip can prevent the keyfob from sending a message to the vehicle's receiver module. The key fob can only start the engine of your Rolls Royce when it receives an indication from the chip.
