Car Immobiliser Repair
In the late 20th century automakers began using car immobilisers because hot-wiring was becoming more popular with thieves. The immobiliser prevents your car's engine from starting in the event that the chip inside the key fob is damaged or does not match.
It is therefore important to repair your car's key immobiliser immediately if it is damaged or malfunctions. Here are a few common causes of your car's immobiliser failing to work:
Dead Batteries
A dead battery is one of the most common causes of key fob issues. Batteries can fail due to prolonged usage or exposure to harsh environmental conditions, or simply ageing. If 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, resulting in the need for a professional to perform an immobiliser system repair.
Most of the time, a simple replacement is all you need to revive a dead battery and get it working again. You can buy a high quality coin-styled battery at your local hardware store or even from general retailers for around $5-10. After you've bought a new battery, take the old one from the fob, and carefully open the case. Look for a slot or notch along the line that divides the top and bottom halves of the fob. Then, insert the tip of an flathead screwdriver or coin into the slot, then move it around the edges. Then, you can insert the new battery and snap the two halves of the fob shut. When you're done your work, you can reuse the old battery at a nearby collection site.
If the new battery isn't able to fix the problem it could be an issue with the RFID system on the key fob itself. In the majority of vehicles that have push-button ignition, the key fob must be placed close to the ignition barrel to confirm its existence. If the RFID inside the key fob cannot communicate with the vehicle, you will have to get a new key made or take it to a dealer to fix the immobiliser.
If changing the batteries doesn't resolve the issue You may need to take the key fob apart to look for buttons that are out of place or damaged. 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 to the Transponder is not working.
A transponder key that is faulty could have severe consequences. Transponder keys are different from conventional keys made of metal, which engage the ignition mechanically. They have an electronic microchip that sends an unique number to the immobilizer system of the vehicle to verify the identity of the key. This adds a layer of security, decreasing the possibility of thefts as well as other crimes committed by vehicles. But, like other electronic device transponder keys are prone to a myriad of issues, including those related to the functionality of the chip.
Transponder chips are delicate and even a slight physical injury can affect their capability to function. This is why it's crucial to regularly inspect your transponder key for signs of wear and tear as any such damage can be a direct cause of a malfunctioning car immobiliser.
Additionally the internal microchip that is in a transponder key is also sensitive to water and other environmental conditions, which could affect the ability of it to communicate with the vehicle's immobilizer system. This is why it is essential to keep your key fob and key chain free from water and other contaminants as much as you can.
It's also important to remember that a transponder key has been specifically programmed to a specific vehicle, and changing any part that is sensitive can lead to compatibility issues that could affect its functionality. It is recommended to not make any modifications to a key unless you're equipped with the right expertise and equipment.
Fortunately, if you've got keys that are in need of repair or replacement, a professional locksmith will be able assist you. They can duplicate the key you have already got or design a new one from scratch and will be able to program it to match your particular vehicle's immobilizer, making sure that it operates properly. This process is not as easy as copying a car key made of metal. It requires special tools to ensure that the software is programmed correctly with the correct information.
Faulty Receiver or Antenna
The transponder chip on your car key sends an electrical signal to the ECU that lets it determine whether the key is the right one to start your vehicle. The immobiliser will stop the engine from starting if it's not the correct key. This is to stop thieves from accessing your car's engine with a stolen or duplicated keys.

It is also possible that the coaxial antenna cable has been damaged or broken. This can happen if your pets run around in the home, or if the cable is twisted during installation.
The receiver could be too far away from the antenna. Connect the receiver to another antenna and test. If the error message is still present it is possible that you need to install an additional antenna or change the route of your coaxial cable.
Antennas aren't necessarily damaged however they may get twisted or pinched or they might come loose from the connector, which can cause the RF level to decrease. Also, you should check if there is any equipment between the antenna and the receiver, for instance a surge protector or splitter, because this could impact the strength of the signal.
If the EEPROM programming method is employed to program a new car key, it involves the removal of specific modules from your car (security components) and then reading the "password" and other stored information from them. This requires a great deal of expertise, as there is a possibility that the data may be corrupted. A professional auto locksmith has a deep knowledge of the circuit board and can minimise the risk by reading 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 stop the engine from starting if the car fob or key isn't in the car. These systems make use of transponder chips, RFID (Radio-Frequency Identification) technology, or immobiliser control units to authenticate the keys or fob after it is put into the ignition.

If you're experiencing this problem follow the instructions of the manufacturer to perform a reset of the system, or contact an expert mechanic to get help.
When you insert the transponder into your key, the chip transmits an alert to the immobiliser system in the car. The code is examined against the codes that are stored on the computer. If the codes coincide, the engine will start and the immobiliser will turn off. If the immobiliser doesn't detect the signal, it'll stop the engine from turning over and can leave you stuck in a strange location.
