Car Immobiliser Repair Car immobilisers became a necessity for automakers at the end of the 20th century because hot-wiring cars became increasingly popular with thieves. The immobiliser blocks the engine of your car from starting when the chip in your key fob has been damaged or doesn't meet. It is therefore important to repair your car 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 Key fob problems are often caused by batteries that are dead. A battery can go bad through long-term use, exposure to harsh environmental conditions, or simply aging. When a battery is damaged and is no longer able to supply the power needed to control the key fob and transmit the signal needed by the immobiliser system. This could prevent the car from starting, which results in the need for a professional to perform an repair to the immobiliser system. In the majority of cases, a simple replacement will revive a dead one. You can buy a high quality coin-styled battery from your local hardware store or even from a few general retailers, for $5-10. When you purchase a new coin-style battery, carefully remove the old one and open the case. You'll find an opening or notch along the seam that separates the bottom and top halves. Push the tip of an flathead screwdriver or coin into the slot, and then work your way around the edges. Then, you can insert the new battery and then snap the two halves of the fob closed. When you're done recycling the old battery at a nearby battery collection site. If the new battery isn't able to fix the problem, it may be a problem with the RFID system on the key fob itself. The majority of vehicles with a push-button ignition design require that the fob be placed close to the barrel of ignition in order to verify its presence and send the right signal to allow the vehicle to start. If the RFID inside the key fob cannot communicate with the vehicle, you'll have to get a new key made or take it to a dealer to repair the immobiliser. If changing the batteries does not resolve the issue You may need to disassemble the key fob to check for any buttons that are not in place or broken. Since your key fob is frequently tossed around when you use it, it's not common for certain buttons to become displaced or stuck in time. Faulty Transponder Key A defective transponder key can be an unfortunate occurrence that can result in serious consequences. Unlike traditional metal keys, that simply mechanically activate the ignition the transponder key is equipped with an electronic microchip that sends an unique code to the immobilizer system to verify its identity prior to being able to start the engine. This adds an additional layer of security that greatly reduces the chance of theft as well as other types of vehicular crime. However, just like any other electronic device transponder keys are prone to a myriad of issues that are related to the chip's functionality. Transponder chips can be fragile and even a small physical damage will affect their capability to function. It's vital to inspect your transponder keys for signs that indicate wear, since these could be the cause of a malfunctioning immobiliser. Additionally the internal microchip that is in a transponder key is also sensitive to water and other environmental conditions, which may hinder the ability of it to communicate with the vehicle's immobilizer system. Therefore, it is important to keep the key fob and the keychain as far away from water as you can. Full Content 's also important to note that a transponder key is specifically programmed to a particular vehicle, and modifying any of the parts that are sensitive could lead to compatibility issues that could affect its function. It's best to avoid any kind of modification to a vehicle key unless you have the proper expertise and equipment to perform the task safely and efficiently. A professional locksmith can help you if your key requires to be repaired or replaced. They can duplicate the key you have already got or create a new one from scratch and they'll be able to program it to work with your specific vehicle's immobilizer system, ensuring that it works as intended. This process is not like copying a car key made of metal. It requires tools that are specialized to ensure that the software is programmed with the correct information. Faulty Antenna or Receiver The transponder chip inside your car key sends a signal that is recognised by the ECU to verify that it's the right key to start the vehicle. If it isn't the correct key, the immobiliser system will stop the engine from starting. This is to stop thieves from accessing your car's engine using stolen or cloned key. However, if the signal isn't able to reach the ECU because of a problem with the receiver or antenna the car won't begin. A professional auto locksmith will be in a position to assist you in resolving this problem. This can result from many factors, such as an antenna that is not compatible or electrical interference. Radio frequency interference (RFI) can be caused by communications equipment and transmitters, cable television systems, computers and digital devices, as well as heavy electrical equipment or lighting systems. It is also possible that the coaxial antenna cable has become disconnected or damaged. This could happen when your pets run around in the home, or if the cable is damaged during installation. Another reason the antenna may not be working is that the receiver may be too far away from the antenna. Connect the receiver to another antenna and then check. If the error message is still present then you may need to replace the antenna or change the coaxial cable. Antennas aren't necessarily damaged however they could be pinched or twisted, or loose from the connector, which can cause the RF level to drop. You should also check whether there is any equipment installed between the antenna and the receiver, like a surge protector or splitter, as this may impact the strength of the signal. If the EEPROM programming method is employed to program a new car key, it will require the removal of specific modules from your vehicle (security components) and then reading the "password" and other stored data from them. This requires great expertise as the information could be corrupted. A professional auto locksmith has a thorough knowledge of the circuit board and can minimise this risk by reading the data directly from the module with a special tool. Faulty Electronics A lot of modern cars are equipped with security systems that block the engine from starting if the car key or fob isn't present. Full Content make use of transponder chips, RFID (Radio-Frequency Identification) technology, or immobiliser control units to authenticate the key or fob once it's inserted into the ignition. This can be a great way to reduce vehicle theft however, like all pieces of technology, it's not always guaranteed to fail. If the security light on your dashboard is lit solid, it indicates that the car immobiliser isn't receiving the signal from the fob or key. This could be due to a number of things, including a depleted battery in the fob or a physical damage to the key. If you're experiencing this issue Follow the manufacturer's guidelines to perform a reset of the system, or contact an expert mechanic for assistance. When you insert the transponder into your key, the chip sends a signal to the immobiliser system in the car. This code is then examined against the codes that are stored on the computer. If the codes match, same the engine will be turned on and the immobiliser will turn off. If the immobiliser does not detect the signal that it is looking for, the engine won't turn over and you may be trapped. There are a myriad of issues that can cause your car's immobiliser to cease working correctly, but the majority of them are fairly easy and affordable to fix. A dying or dead keyfob battery is the most common issue, and it can be easily identified by an easy diagnostic test. If this doesn't resolve the issue, it could be due to other issues with the electrical system in your vehicle that are impacting the functioning of the immobiliser. If this is the situation it is recommended that a professional examine your car's electrical system and look for indications that it could be affected by damaged connections or loose connections.
