Car Immobiliser Repair
In the latter part of the 20th century, automakers began to use car immobilisers due to hot-wiring becoming more popular with thieves. The immobiliser blocks your vehicle from starting if your key fob chip is damaged or does not match.
This means that it is essential to get your car's key immobiliser repair completed promptly if it's malfunctioning or damaged. Here are some of the common causes for the immobiliser on your car not working:
Dead Batteries
A dead battery is one of the most frequent causes of key fob problems. The battery can degrade from prolonged usage or exposure to harsh environmental conditions, or simply aging. When a battery fails in its function, it will not transmit the signal required by the immobiliser and operate the key fob. This could prevent the car from starting, which results in the need for a professional to perform an immobiliser system repair.
In most cases, a simple battery replacement will revive the battery that was dead. You can buy a high quality coin-styled battery at your local hardware store, or even from a few general retailers, for around $5-10. Once you've purchased a brand new battery, remove the old one from the fob, and carefully open the case. There's an opening or notch along the seam that separates the top and bottom halves. Then, insert the end of an screwdriver with a flathead or coin into the slot and work it around the edges to open the fob. Then, insert the new battery and then snap the two halves of the fob shut. Once you've finished, you can recycle the old battery at a nearby collection site.
If the new battery does not fix the problem, there may be an issue with the RFID system inside the key fob. In most vehicles that feature ignition that is push-button, the fob is required to be positioned close to the barrel of ignition to confirm its presence. If the RFID inside your key fob isn't able to communicate with the vehicle, you'll have to have the key made for your vehicle or take it to the dealership to have an immobiliser repaired.
If changing the battery doesn't resolve the problem it's worth disassembling the key fob and looking for any buttons that seem out of place or broken. Because your key fob is constantly tossed around when you use it, it's not unusual for some of the buttons to get stuck or misaligned over time.
Key for transponder not working
A transponder key that is defective can result in serious consequences. Transponder keys are different from the traditional keys made of metal that engage the ignition mechanically. They feature an electronic microchip that transmits a unique number to the immobilizer system of the car to confirm its identity. This adds an extra layer of security, which reduces the chance of thefts and other crimes committed by vehicles. Transponder keys, as with any electronic device, are vulnerable to a variety of issues that are related to the chip's purpose.
Transponder chips are extremely delicate, and even a small amount of physical damage can affect their ability to function. This is the reason it's essential to regularly check your transponder key for signs of wear and tear since any damage could be the direct cause of a malfunctioning car immobiliser.
The microchip inside transponders is also sensitive to moisture and other environmental conditions. This could affect the ability of a key to communicate with an immobilizer system. This is why it's important to keep your key fob and key chain free from any water or other contaminants as much as possible.
It's also important to remember that a transponder key has been specifically programmed to a specific vehicle, and changing any sensitive parts can result in compatibility issues that can affect its functionality. Therefore, it's best to avoid any kind of modification to a vehicle key, unless you have the proper knowledge and equipment to perform the task safely and effectively.

Faulty Receiver or Antenna
The transponder chip inside your car key transmits a signal that is recognised by the ECU to ensure that it is the correct key to start the car. The immobiliser prevents the engine from starting if it's not the correct key. This is to prevent thieves from gaining access to your car's engine by using a stolen or copied keys.

Radio frequency interference (RFI) can be caused by communications equipment and transmitters, computer systems, cable television systems and digital devices, heavy electrical equipment or lighting systems. It's also possible that a coaxial antenna cable has been damaged or broken. This could happen if your pets run around in the house, or if the cable is bent during installation.
Another reason the antenna may not be working is because the receiver is far from the antenna. You can check this by connecting the receiver to a different antenna. If the error message is still present then you might require a new antenna or reroute your coaxial cable.
Antennas are not bad, but can be bent, pinched or loose from their connectors, which can cause the RF quality of the signal to decrease. Examine if there's anything between the antenna and the receiver, like a surge protector, splitter or splitter, which could affect the strength of the signal.
If you are using the EEPROM method to program a car key, you will require the removal of specific modules (security components) from your vehicle and then read the "password" from them. This requires great expertise as the information could be corrupted. A professional auto locksmith has a deep understanding of the circuit board and can minimize this risk by reading the data directly from the module using an instrument that is specifically designed for this purpose.
Faulty Electronics
Many modern cars are fitted with security systems that prevent the engine from beginning if the car's ignition fob or key aren't present.

If you're experiencing this issue, follow the manufacturer's instructions to perform a reset of the system, or call a professional mechanic for assistance.

If the codes match, identical, the engine will turn on and the immobiliser shuts off. If the immobiliser is unable to detect the signal it will not turn over and you could be left stranded.
