Dead Batteries
Key fob issues are usually caused by a dead battery. The battery can degrade from prolonged usage or exposure to harsh environmental conditions, or simply aging. If a battery fails, it will no longer provide the power required to operate the key fob and send the signal needed by the immobiliser system. This could stop the car from starting, resulting in the need for a professional to perform an repair of the immobiliser system.
In most instances, a simple battery replacement can bring back an old one. You can purchase a good quality coin-styled batteries at your local hardware store or even from a few general retailers for around $5-10.

When you're done recycling your old battery at a collection site near you.
If the new battery fails to fix the problem, there may be an issue with the RFID technology within the key fob. In the majority of vehicles that have push-button ignition, the fob must be held close to the barrel of ignition to confirm its presence. If the RFID inside the key fob isn't able to connect with the vehicle, you'll have to make a key specifically for your vehicle, or take it to a dealer to have an immobiliser repaired.

Faulty Transponder Key
A faulty transponder key is an unfortunate incident that could have serious consequences. Transponder keys are different from the traditional keys made of metal that engage the ignition mechanically. They are equipped with an electronic microchip that transmits a unique number to the immobilizer system of the vehicle to confirm its identity. This provides an additional layer of security, decreasing the chance of thefts and other vehicular crimes. But, like other electronic device transponder keys are prone to a myriad of issues that are related to the chip's function.
Transponder chips are delicate and even a small physical damage can impact their ability to work. It is essential to check your transponder keys for signs that indicate wear, since these could be the reason for an immobiliser malfunction.
The microchip inside transponders are also sensitive to humidity and other environmental conditions. This can interfere with the ability of keys to communicate with an immobilizer system. Therefore, it is important to keep your key fob and key chain free from a variety of contaminants and water as much as is possible.
remote key repair is important to keep in mind that a transponder car key is programmed specifically for a specific vehicle. Making any changes to the sensitive parts could result in compatibility issues that could compromise its function.

This isn't as easy as copying a regular car key made of metal, and it requires the use of specific tools to ensure that the right information is entered into the software.
Faulty Antenna or Receiver
The transponder chip inside your car key transmits an electrical signal to the ECU that allows it to verify whether or not the key is the right one to start the vehicle. The immobiliser stops the engine from starting when it's not the right key. This is a way to prevent thieves from using stolen or duplicate keys to access your car's motor.

The receiver may be too far from the antenna. Connect the receiver to a different antenna and check. If the error message remains it is possible that you require a new antenna or redirect the coaxial cable.
Antennas aren't necessarily bad, but can be pinched, twisted or detached from their connectors, which can cause the RF quality of the signal to drop. Check if there is anything between the antenna and the receiver, like a surge protector, splitter or splitter, which could affect the strength of the signal.
If the EEPROM programming method is used to program a new car key, it requires the removal of specific components from your car (security components) and reading the "password" and other stored data from them. This requires expertise as the information could be corrupted. A professional auto locksmith has a deep knowledge of the circuit board and can reduce the risk by reading data directly from the module with a special tool.
Faulty Electronics
A lot of modern vehicles have security systems that prevent them from starting the engine in the event that they don't have a car key or remote.
