Car immobilisers became a necessity for automakers in the latter part of the 20th century as hot-wiring vehicles was becoming increasingly popular among thieves. The immobiliser blocks your car from starting if your key fob chip is damaged or doesn't match.
This means it's essential to get your car's immobiliser repaired quickly if it's damaged or damaged. Here are a few common causes for your car's immobiliser not working:
Dead Batteries
A dead battery is one of the most frequently cited reasons for key fob issues. Battery problems can be caused by long-term use or harsh environmental conditions, or ageing. If a battery fails, it will no longer provide the power required to operate the key fob and transmit the signal required by the immobiliser system. This could prevent the car from starting, which results in the need for a professional to perform an repair of the immobiliser system.
Most of the time replacing the battery is all that is required to revive an old battery and make it functional again. A good coin-style battery can be found at a local hardware shop or even some general retailers for between $5-10. Once you've purchased a new battery, take the old one from the fob and carefully open the case. You'll find an opening or notch along the seam that separates the top and bottom halves.

Once you are done, you can recycle your old battery at a battery collection facility near you.
If the new battery doesn't solve the issue it could be an issue with the RFID system on the key fob itself. Most vehicles with a push-button ignition design require the fob to be placed close to the ignition barrel to confirm its presence and send the proper signal for the vehicle to start. If the RFID in the key fob is not able to communicate with the vehicle, you'll have to get a new key made or take it to a dealership to repair the immobiliser.
If changing the batteries doesn't solve the issue it's possible to remove the key fob to find any buttons that are not in place or broken. It's common that buttons become out of alignment over time, because your key fob is likely be tossed around frequently.
Key to the transponder is not working properly.
A transponder key that is defective can result in serious consequences. Transponder keys are different from conventional keys made of metal, which engage the ignition mechanically. They are equipped with an electronic microchip that transmits a unique number to the immobilizer system in the car to confirm its identity. This adds an additional layer of security that greatly reduces the possibility of theft as well as other types of vehicular crime. Transponder keys, like any electronic device, are vulnerable to a variety of issues, including those relating to the chip's purpose.
Transponder chips are fragile and even a small amount of physical damage can significantly impact their ability to function. This is why it's crucial to regularly check your transponder key for indications of wear and tear, since any damage could be the direct cause of malfunctioning car immobiliser.
The internal microchip of transponders are also sensitive to humidity and other environmental conditions. This can affect the ability of the key to communicate with an immobilizer system. It's therefore important to keep the key fob and keychain as far from water as is possible.
It's also important to remember that a transponder is specifically programmed to a particular vehicle, and changing any sensitive parts can lead to issues with compatibility that could impact its functionality. Therefore, it's best to avoid any form of modification to a car key unless you have the proper knowledge and tools to do it safely and effectively.

Antenna or Receiver that is not working properly
The transponder chip inside your car key transmits signals to the ECU that allows it to determine whether the key is the correct one to start the car. The immobiliser prevents the engine from starting if it's not the correct key. This is to stop thieves from accessing your vehicle's engine with a stolen or duplicated keys.

The receiver might be too far from the antenna. You can check this by connecting the receiver to another antenna. If the error message is still present then you might require a new antenna or reroute your coaxial cable.
Antennas aren't good, but they could be twisted, pinched, or come loose from their connectors, which can cause the RF strength of the signal to drop. It is also important to determine if there is any equipment between the antenna and the receiver, such as a surge protector or splitter as this may influence the signal strength.
If the EEPROM programming method is employed to program a new car key, it will require extracting specific components from your car (security components) and then reading the "password" and stored data from them. This requires a lot of expertise since the data could be damaged.

If you're experiencing this issue follow the instructions of the manufacturer to reset the system, or contact a professional mechanic to get help.
When you insert the transponder chip in your key, it sends a code to the car's immobiliser system which is then compared to the codes that are stored in the computer. If the codes match the engine will begin and the immobiliser will turn off. If the immobiliser isn't able to detect the signal, it'll stop the engine from turning and could cause you to be stuck in a strange area.
