Why Your Rolls Royce Remote Key Isn't Working
If your Rolls Royce Phantom key remote isn't working it could be due to one of the problems that are listed below. It could be due to a dead battery in the coin-cell, water damage, or a defective microchip that needs to reprogrammed.
The keys should be stored in a dry location away from electrical or wet areas. If you've done this and it doesn't work, you can try the following steps:
Fault Diagnosis
Rolls Royce is a sophisticated well-established and well-known brand of cars with a focus on excellence. It is therefore crucial to ensure regular maintenance to avoid major issues in the future which could cost you money and be time-consuming to fix. The most important maintenance task is to clear and read fault codes. The fault codes are small SOS messages sent by your vehicle's complex electronic system. It's like ignoring a persistent cold - they could be an indication of a bigger issue.
There are a variety of reasons why your key fob could not function properly. The Keylab could be caused by the battery in the coin-cell being dead, water damage or interference in the signal, receiver module problems or a malfunctioning chip. If you have tried everything from replacing the battery to reprogramming it and the problem persists, it may be the right time to take your Rolls Royce to a professional for further troubleshooting.
The battery is the first thing you need to check when a key fob isn't working. A battery that is drained of its capacity is the most common reason for the key fob not to be functioning. It is vital to replace the battery with a button-cell battery that has the same voltage, size, and specification as the original. It is also recommended that you store the key fob in a safe place and away from any objects that could cause mechanical damage, such as keys or coins.
When you replace the battery, make sure that all metal retaining clips are in place and will not cause any contact issues. Make sure that the battery is clean and free of harmful substances. If the battery is not genuine replacement for the Rolls-Royce it could be damaged by unsuitable components and cause the receiver module to fail or even make the doors unlocked.
Faulty Receiver Module
If your key fob suddenly stopped working, and you tried everything to fix it (replaced the battery for the coin and reprogrammed it, and even bought an extra) it could be a problem with the module that decodes and receives remote control signals. This is true especially if the key fob works with a different vehicle.
The receivers inside the key fobs have 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. In certain situations, the receiver module could be unable to function due malfunctioning electronic chips.

Key Fob Not Working
Your key fob could not function due to a variety of factors. Often, the first problem is a dead coin battery, which can be easily replaced in minutes. Damage to the receiver module, water issues, or signal interference may cause the key fob to stop working. You can identify these issues by disassembling the key fob and applying isopropyl alcohol or electronic cleaner to the chip inside.
Another reason could be worn buttons. Remote controls for key fobs in cars feature rubberized buttons that could be worn out or loose over time. This causes an interruption in contact between the button and the pressure points, which causes it to malfunction. This is an easy fix for the majority of key fobs that can be done at home by disassembling the key by removing the buttons and cleaning them. Soldering them back to their original position will restore the functionality.
Other reasons for a faulty keyfob include the battery's 12 volts being dead keys that aren't properly paired and require replaced or a defective chip. A damaged chip can stop the key fob from sending a signal to the receiver module of your vehicle. The key fob will start the engine of your Rolls Royce when it receives an acceptable signal from the chip.
Sometimes, a push-button start key can get hacked by tech-savvy thieves. These thieves can use artificial intelligence to detect the unique signal sent by the fob of the key, unlocking or activating the ignition of your car. This kind of hacking is becoming less prevalent due to security measures that have been improved over time.
