It is crucial to repair your car's key immobiliser immediately if it becomes faulty or damaged. Here are the most common causes of your car's immobiliser not working: work:
Dead Batteries
A dead battery is one of the most common causes of key fob issues. Batteries can fail from long-term usage, exposure to harsh environmental conditions, or simply aging. If a battery fails and is no longer able to supply the power needed to control the key fob and send the signal required by the immobiliser system. This can stop your vehicle from starting and may require a professional to repair the immobiliser system.
Most of the time an easy replacement is all that is required to revive the battery that has died and get it working again. You can buy a high quality coin-styled batteries at your local hardware store or even from a few general retailers, for $5-10. After purchasing the latest coin-style battery carefully remove the old one and open the casing. There's an opening or notch on the seam separating the bottom and top halves. Then, insert the tip of a flathead screwdriver or coin into the slot, then work your way around the edges. Then, you can insert the new batteries and snap the two halves together. When you're done recycling the old battery at a nearby collection site.
If the new battery does not fix the problem, there could be a problem with the RFID system inside the key fob. Most vehicles that have an ignition system that uses a push button require that the fob be placed close to the barrel of ignition to verify its presence and send the correct signal to allow the vehicle to start. If the RFID on your key fob isn't in a position to communicate with the vehicle, you'll have to get the key made specifically for your vehicle, or take it to the dealer to have an immobiliser repaired.

Faulty transponder key
A transponder key that is defective can have serious consequences. Transponder keys differ from conventional keys made of metal, which engage the ignition mechanically. They feature an electronic microchip that transmits an individual number to the immobilizer system in the car to confirm its identity. This adds a layer of security, which reduces the possibility of thefts as well as other vehicle-related crimes. Transponder keys, like any electronic device, are prone to a variety of issues that are related to the function of the chip.
Transponder chips are extremely delicate, and even a small amount of physical damage could significantly impact their ability to function. This is why it's important to check your transponder key for indications of wear and tear because any damage that occurs could be the direct cause of an immobiliser malfunctioning in your car.
In addition the internal microchip that is in the transponder key is sensitive to water and other environmental conditions, which could interfere with the ability of it to communicate with the vehicle's immobilizer system. It is therefore essential to keep the key fob as far away from water as possible.
It's also important to keep in mind that a transponder key has been specifically programmed for a specific vehicle, and changing any part that is sensitive can result in issues with compatibility that could impact the functionality of the key. It is recommended to not make any changes to a key unless you're equipped with the right knowledge and equipment.

A faulty Receiver or Antenna
The transponder chip inside your car key transmits signals to the ECU that allows it to verify whether the key is the right one to start the car. The immobiliser prevents the engine from running if it's not the correct key. This is done to prevent thieves from gaining access to your car's engine with a stolen or duplicated keys.

The receiver may be too far away from the antenna. You can check this by connecting the receiver to another antenna. If the error message is still present it is possible that you require a new antenna or reroute your coaxial cable.
Antennas aren't necessarily bad, but can be bent, pinched or loose from their connectors, which can cause the RF quality of the signal to decrease. Also, you should check if there is any equipment between the antenna and the receiver, like a surge protector or splitter, since this can influence the signal strength.
If you use the EEPROM method to program a car key, you will need to extract specific modules (security components) from your vehicle and read the "password" from them. This requires a lot of expertise, since there is a chance that the data may be damaged. A professional auto locksmith will reduce the risk by reading data directly from the module with a specific tool.
Faulty Electronics
Many modern cars come with security systems that block them from starting the engine in the event that they don't have a remote or key to the car. These systems employ transponder chips, RFID (Radio-Frequency Identification) technology, or immobiliser control units to authenticate the keys or fob once it's inserted into the ignition. This is a great way to stop theft from vehicles however, like all pieces of electronic equipment, it's possible to fail.
If the security light on your dashboard is solid, that means the car immobiliser isn't receiving the signal from the fob or key.

If you're experiencing this problem Follow the manufacturer's guidelines to reset the system, or call an expert mechanic to get help.
When you put the transponder chip inside your key, it sends an encoded code to the immobiliser system in your car that is then compared with the codes that are stored in the computer. If the codes are the same the engine will turn on and the immobiliser will shut off. If the immobiliser fails to recognize the signal, it will prevent the engine from turning over and may leave you stuck in a remote place.
