The immobiliser blocks your car's engine from starting when the chip in your key fob is damaged or doesn't match. It is crucial to repair your car's key immobiliser when it starts to fail or is damaged. Here are a few common causes for the immobiliser of your car not working: Dead Batteries Key fob issues are usually caused by a dead battery. Battery problems can be caused by prolonged use and harsh environmental conditions as well as getting older. If a battery fails it will not supply the power needed to control the key fob, and also transmit the signal required by the immobiliser system. This could stop your car from starting and need a professional repair the immobiliser system. In most instances, a simple battery replacement will revive the battery that was dead. You can purchase a good quality coin-styled batteries at your local hardware store or even from general retailers for around $5-10.

Find an opening or notch along the edge that separates the bottom and top halves of the fob. Use the screwdriver, either flathead or coin, into the slot and then work around the edges until you can open the fob. Then, you can insert the new battery and snap the two halves of the fob closed. After you've completed the process your work, you can reuse the old battery at a nearby collection site. If the new battery does not solve the issue, it may be a problem with the RFID technology in the key fob itself. The majority of vehicles with an ignition system that uses a push button require the fob to be placed close to the ignition barrel in order to verify its presence and send the correct signal for the vehicle to start. If the RFID on the key fob cannot communicate with the vehicle, you will need to have a new key or go to a dealer to repair the immobiliser. If changing the battery doesn't solve the issue It's worth taking the key fob apart and examining any buttons that seem to be not in the right place or are damaged. Since your key fob is constantly tossed around when you use it It's not uncommon for some of the buttons to become displaced or stuck in time. Key for the Transponder that isn't working A damaged transponder key is an unfortunate event that could result in serious consequences. Transponder keys are different from traditional metal keys that engage the ignition mechanically. They have an electronic microchip that transmits a unique number to the immobilizer system in the car to confirm its identity. This adds an additional layer of security that greatly reduces the chance of theft as well as other types of vehicular crime. But, like other electronic device transponder keys are prone to a variety of problems which include those that concern the chip's functionality. Transponder chips are extremely delicate and even a tiny amount of physical damage could affect their ability to function. It is crucial to examine your transponder keys for signs that indicate wear, as they could be the reason for an immobiliser that is not working properly. The microchip inside transponders is also sensitive to environmental and moisture conditions. This can affect the ability of keys to communicate with an immobilizer system. It is therefore essential to keep the key fob and keychain as far away from water as possible. It's also important to keep in mind that a transponder is specifically programmed to a specific vehicle, and altering any sensitive parts can lead to issues with compatibility that could impact its functionality. It's best to avoid making any modifications to a key unless you're equipped with the right expertise and equipment. If you're in the unfortunate position of having an old key that is in need of repair or replacement, a professional locksmith will be able help you out. They can duplicate your key or create an entirely new one and program it to match the immobilizer system in your vehicle, making sure it is working correctly. This process isn't as simple as simply copying a car key made of metal. It requires specialized tools to ensure the software is programmed with the proper information. Antenna or Receiver that is not working properly The transponder chip inside the key of your car transmits a signal to the ECU that allows it to determine whether the key is the right one to start the car. The immobiliser will stop the engine from starting if it's not the correct key. This is to stop thieves from using stolen or cloned keys to gain access to your car's motor. If the signal isn't able to reach the ECU because of a problem with the antenna or receiver the car won't begin. A professional auto locksmith is capable of helping you solve this problem. This could be due to a number of reasons which include an antenna that isn't compatible or an electrical interference issue. Radio frequency interference could be caused by heavy electrical equipment, lighting systems computers, digital devices, cable television systems and transmitters. It is also possible that the coaxial antenna cable has become disconnected or damaged. This could occur when pets wander around the house or when the cable is bent or damaged during installation. Another reason why the antenna might not be working is because the receiver may be too far away from the antenna. Connect the receiver to a different antenna and check. If the error message is still present, you may need to install an additional antenna or change the route of your coaxial cable. Antennas aren't necessarily bad, but can be twisted, pinched or detached from their connectors, causing the RF strength of the signal to decrease. Check if there is anything between the antenna and the receiver such as a surge protector, splitter, or splitter, which could affect the strength of the signal. If the EEPROM programming method is used to program a new car key, it will require extracting specific components from your car (security components) and then reading the “password” and other stored data from them. This requires a lot of expertise since the information could be corrupted. A professional auto locksmith can minimise the risk by reading information directly from the module with a specific tool. Faulty Electronics A lot of modern cars are equipped with security systems that stop the engine from starting if the car fob or key isn't in the car. These systems employ transponder chips, RFID (Radio-Frequency Identification) technology, or immobiliser control units to authenticate the keys or fob when it's placed in the ignition. It's an effective way to curb vehicle crime however, it could also be a disaster. If the security light on your dashboard is solid, it means that the car immobiliser isn't accepting the signal from the key or fob. This can be caused by a variety of factors, such as a battery that is depleted on the keyfob, or physical damage on the key. If you're experiencing this problem follow the instructions of the manufacturer to reset the system, or consult a professional for help. When you insert the transponder into your key, the chip sends a signal to the immobiliser system of the car. This code is then examined against the codes that are stored on the computer. If the codes match the engine will begin and the immobiliser will turn off. If the immobiliser isn't able to detect the signal, it'll stop the engine from turning over and may leave you stuck in a remote location. There are a myriad of issues that can cause the car's immobiliser to stop working correctly, but the majority of them are easy and inexpensive to address. The most common cause is a dying or dead key fob battery that can be easily identified with a quick diagnostic test. If car key repair shop near me does not solve the issue, it could be due to other issues with the electrical system of your vehicle that could be affecting the immobiliser's function.
