Car Immobiliser Repair In the late 20th century automakers began using car immobilisers because hot-wiring was becoming more popular among thieves. The immobiliser stops your vehicle 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 starts to fail or is damaged. Here are some of the most common reasons for the immobiliser of your car not working: Dead Batteries Key fob issues are usually caused by the battery being dead. Problems with batteries can be caused by prolonged use or harsh environmental conditions, or ageing. If a battery is damaged, it can no longer transmit the signal required by the immobiliser to operate the key fob. This can prevent the vehicle from starting, resulting in the requirement for a professional to perform an repair of the immobiliser system. Most times an easy replacement is all that is required to revive an old battery and get it working again. You can buy a high quality coin-styled battery from your local hardware store, or even from some general retailers for around $5-10. When you purchase a new coin-style battery, remove the old one and then open the case. Find a slot or notch along the edge that separates the bottom and top halves of the fob. Push the tip of a flathead screwdriver or coin into the slot, then move it around the edges. Then, you can insert the new batteries and then snap the two halves together. Once you are done recycling the old battery at a collection facility close to you. If the new battery does not solve the issue, it may be a problem with the RFID system in the key fob itself. Most vehicles that have a push-button ignition design require the fob to be held up close to the barrel of ignition to confirm its presence and send the correct signal for the vehicle to start. If the RFID inside the key fob isn't able to communicate with the vehicle, you'll have to make a key for your vehicle or take it to the dealer to have an immobiliser repaired. If changing the battery does not solve the issue it's worth disassembling the key fob and examining any buttons that seem to be out of place or broken. Because your key fob is frequently tossed around as you use it, it's not common for certain buttons to get stuck or misaligned over time. Key for transponder not working A damaged transponder key is an unfortunate occurrence that can cause serious damage. Unlike traditional metal keys, which merely mechanically engage the ignition the transponder key is equipped with an electronic microchip which transmits a unique code to the immobilizer system, verifying its identity before permitting it to start the engine. This provides an additional layer of security, decreasing the chance of thefts and other vehicle-related crimes. But, like other electronic device transponder keys are subject to a variety of problems, including those related to the chip's functionality. Transponder chips are delicate and even a tiny amount of physical damage can severely affect their capacity to function. It's vital to inspect your transponder keys to see if there are signs of wear, since these could be the reason for an immobiliser malfunction. In addition, the internal microchip in the transponder key is sensitive to environmental and water conditions, which could affect the ability of it to communicate with the immobilizer system of a vehicle. It's therefore important to keep the key fob and keychain as far from water as you can. It's important to remember that the transponder car key is programmed specifically for a specific vehicle. Modifying any of the parts that are sensitive could lead to compatibility problems that could affect its functionality.

Receivers or Antennas that are not working properly The transponder chip inside your car key sends signals that are recognized by the ECU to confirm that it's the correct key to start the car. If it isn't then the immobiliser will stop the engine from beginning. This is done to prevent thieves from accessing your vehicle's engine by using a stolen or copied key. However, if the signal fails to reach the ECU because of a problem with the receiver or antenna, your car won't start.

Another reason the antenna may not be functioning is that the receiver may be too far away from the antenna. Connect the receiver to a different antenna and then check. If the error message persists, you may need to install a new antenna or reroute your coaxial cable. Antennas aren't bad, but they can be pinched, twisted or detached from their connectors, causing the RF quality of the signal to decrease. It is also important to determine if there is any equipment between the antenna and the receiver, like a surge protector or splitter, as this may impact the strength of the signal. If you choose to use the EEPROM method to program a car key, you'll need to extract specific modules (security components) from your vehicle and read the “password” from them. This requires expertise as the information could be corrupted. A professional auto locksmith will minimise the risk by reading data directly from the module a specific tool. Faulty Electronics A lot of modern cars are equipped with security systems that stop the engine from beginning if the car's ignition fob or key isn't in the car.

If you're experiencing this problem follow the instructions of the manufacturer to reset the system, or call an expert mechanic for assistance.
