Car Immobiliser Repair
Car immobilisers were a necessity for automakers at the end of the 20th century, as hot-wiring cars was becoming more popular among thieves. The immobiliser blocks your car from starting if your key fob chip is damaged or does not match.
It is therefore important to fix your car's key immobiliser as soon as it is damaged or malfunctions. Here are some of the common causes for the immobiliser of your car not working:
Dead Batteries
A dead battery is one of the most frequent causes of key fob problems. Battery problems are often caused by prolonged use or harsh environmental conditions, or getting older. When a battery fails, it can no longer 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 carry out an immobiliser system repair.
Most of the time replacing the battery is all that is needed to revive the battery that has died and make it functional again. A high-quality coin-style battery can be purchased at a local hardware shop or at some general retailers for between $5-10. After you've bought a new battery, take the old one from the fob and then carefully open the case. Find a slot or notch along the line that divides the bottom and top halves of the fob. Use an flathead screwdriver or coin into the slot, then move it around the edges. Then, you can insert the new batteries and snap the two halves together. Once you are done, you can recycle the old battery at a collection center close to you.
If the new battery isn't able to fix the problem it could be a problem with the RFID technology in the key fob itself. In most vehicles with push-button ignition, the fob must be held close to the barrel of ignition to verify its presence. If the RFID in the key fob does not communicate with the vehicle, you will be required to have a replacement key made or take it to a dealer to repair the immobiliser.
If changing the batteries doesn't solve the issue, you may want to disassemble the key fob to find any buttons that are out of position or are damaged. Because your key fob is constantly tossed around as you use it and it's not unusual for some of the buttons to become displaced or stuck in time.
Key to the transponder is not working properly.
A faulty transponder key is an unfortunate event that could have serious consequences. In contrast to traditional keys made of metal, which merely mechanically engage the ignition keys, transponder keys are equipped with an electronic microchip which transmits an unique code to the car's immobilizer system, which confirms its identity before being able to start the engine. This provides a layer of security that significantly reduces the chance of theft as well as other types of vehicle crime. Transponder keys, like any other electronic device, are prone to a variety of issues related to the function of the chip.
Transponder chips can be delicate and even a slight physical injury can affect their capacity to function. It is crucial to examine your transponder keys for signs that indicate wear, since these could be the reason for a malfunctioning immobiliser.
Additionally, the internal microchip in a transponder key is also sensitive to environmental and water conditions, which can also interfere with its ability to communicate with a vehicle's immobilizer system. Therefore, it is important to keep your key fob and key chain safe from any water or other contaminants as much as you can.
It's also important to remember that a transponder key has been specifically programmed to a particular vehicle, and modifying any of the parts that are sensitive could result in compatibility issues that can affect the functionality of the key. Therefore, it's best to avoid any kind of modification to a vehicle key in the absence of the appropriate knowledge and equipment to do so safely and effectively.
Fortunately, if you've got keys that are in need of repair or replacement, a professional locksmith will be able to assist you. They can duplicate your key or design new keys, and program it to match the immobilizer mechanism of your vehicle, ensuring that it functions properly. This process is not as easy as replicating a key from a car. It requires special tools to ensure that the software is programmed with the proper information.
Faulty Receiver or Antenna
The transponder chip in your car key transmits signals to the ECU that allows it to verify whether it is the right one to start the vehicle. The immobiliser prevents the engine from running in the event that it isn't the correct key. This is to stop thieves from using stolen or duplicate keys to gain access to your vehicle's motor.
If the signal cannot be accepted by the ECU due to a problem with the antenna or receiver the car won't start. A professional auto locksmith will assist you in resolving these issues.

Radio frequency interference (RFI) can be caused by communications equipment and transmitters, cable television systems, computers and digital devices, large electrical equipment or lighting systems. The coaxial antenna cable may have been damaged or cut off. This could occur when pets wander around the house, or if the cable gets twisted or damaged during installation.
Another reason the antenna may not be functioning is that the receiver might be too far from the antenna. Connect the receiver to another antenna and test. If the error message persists 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 strength of the signal to drop. Check if there is anything between the receiver and antenna such as a surge protector, splitter or splitter that could impact the strength of the signal.
If the EEPROM programming method is used to program a new car key, it involves the removal of specific modules from your car (security components) and reading the "password" and stored data from them. This requires a great deal of knowledge, as there is a possibility that the data could be damaged. A professional auto locksmith has a comprehensive knowledge of the circuit board and can minimize this risk by reading the data directly from the module using a specific tool.
Faulty Electronics
Many modern vehicles are equipped with security systems that stop the engine from beginning if the car's ignition fob or key isn't in the car. These systems use RFID (Radio Frequency Identification) or immobiliser controls to authenticate a fob or key that is placed into the ignition.
