If your Rolls Royce Phantom remote key isn't functioning, it could be because of one of the following problems. It could be due to a dead battery in the coin-cell, water damage, or a damaged microchip that requires reprogramming.

Fault Diagnosis
Rolls Royce has a reputation as a well-established, sophisticated automotive brand that is committed to excellence. Regular maintenance is important to avoid costly and time-consuming issues in the future. The most important task for maintenance is to read and clear fault codes. Fault codes are like tiny SOS signals that come from your vehicle's sophisticated electronic system, and ignoring them is akin to ignoring a persistent cough which could be a sign of a bigger underlying problem.
There are many reasons the key fob might cease to function. This could be caused by the battery in the coin-cell being dead or water damage, or an interference in the signal, problems with the receiver module or a malfunctioning chip. If you've tried everything from replacing the battery to reprogramming, and the issue persists, it may be best to take your Rolls Royce in to a expert to help you resolve the issue.
The battery is the first thing to check when a key fob ceases to function. A drained coin battery is the most frequent reason for a key fob to stop functioning. It is crucial to replace the battery with a button battery with the same size, voltage and specifications as the original. It is recommended that the key fob is kept in a safe location away from any objects like keys or coins that could cause mechanical damage.
After you replace the battery, make sure that all the metal retaining clips remain in place and do not cause any contact issues. Make sure the battery is free of corrosion-causing substances. If the battery isn't a genuine Rolls-Royce Replacement, it may be damaged by unsuitable parts and cause the receiver module or doors to close.
Faulty Receiver Module
If your key fob suddenly stopped working and you tried everything to fix it (replaced the battery in the coin and reprogrammed it, and even got an extra) It could be a problem with the module that receives and decodes remote control signals. This is especially true when the key fob is compatible with another vehicle.
The receiver modules in the key fobs feature clips of metal that keep the battery in place and complete the circuit when the buttons are pressed. They may be damaged or bent, which can cause the key fob from receiving the correct signal to unlock/lock the car. The receiver module could also stop working due to an incompatible chip.
Key fob not working properly
If your device stops working, it may be due to a number of reasons. The most common issue is usually a dead coin-cell battery. This is easily replaced in just a few minutes. Damage to the receiver module, water problems or signal interference can also cause the key fob to stop working. You can check for these issues by disassembling your key fob and applying isopropyl alcohol or electronic cleaner to the chip inside.
Another reason could be worn buttons. rolls royce car keys for car keys feature rubberized buttons that could be worn out or loose over time. This causes a loss of contact between the button and the pressure points, causing it to malfunction. It is easy to fix most key fobs at home. Simply take apart the key, take out the buttons, and clean them. Soldering them back to their original position will restore the functionality.
Other reasons for the malfunctioning keyfob could be the battery's 12 volts being dead, keys that are not properly paired and require reprogrammed or a defective chip. A malfunctioning electronic chip can prevent the keyfob from sending an alert to the vehicle's receiving module. The key fob will only start the engine of your Rolls Royce when it receives an appropriate signal from the chip.
Occasionally, a push-button start key may be stolen by hackers who are tech-savvy. These thieves can use artificial intelligence to pick up the unique signal generated by the fob of the key and then unlock or even activate the ignition system of your car. Fortunately, this type of hack is becoming increasingly rare due to security measures that have improved significantly over time.
