Car Immobiliser Repair
In the latter half of the 20th century automakers began using car immobilisers due to hot-wiring becoming more popular among thieves. The immobiliser stops your car from starting if the key fob chip is damaged or doesn't match.
It is therefore essential to repair your car key immobiliser as soon as 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 batteries that are dead. A battery can go bad from prolonged usage or exposure to harsh environmental conditions or simply ageing. When a battery is damaged, it will no longer provide the power necessary to control the key fob and send the signal needed by the immobiliser system. This could prevent the vehicle from starting, resulting in the requirement for a professional to carry out an immobiliser system repair.
In most cases, a simple replacement will revive an old one. You can purchase a top quality coin-styled batteries at your local hardware store, or even from a few general retailers, for $5-10. When you purchase the latest coin-style battery carefully take the old one off and open the casing. You'll find a slot or notch along the seam that separates the top and bottom halves. Push the end of the screwdriver, either flathead or coin, into the slot and work it around the edges to pop open the fob. Then, you can insert the new batteries and then snap the two halves together. Once you are done you can reuse your old battery at a collection center near you.
If the new battery fails to solve the issue, it may be an issue with the RFID system within the key fob. The majority of vehicles with the push-button ignition feature require that the fob be held up close to the barrel of ignition to verify its presence and send the right signal for the vehicle to start. If the RFID on the key fob does not communicate with the vehicle, you'll have to get a new key or go to a dealer to repair the immobiliser.
If changing the batteries does not solve the problem, you may want to take the key fob apart to look for buttons that are out of position or are damaged. It's common for buttons to become misaligned over time, as your key fob is bound to be tossed around frequently.
Key for transponder not working
A transponder key that is defective can have serious consequences. Transponder keys differ from conventional keys made of metal, which engage the ignition mechanically. They have an electronic microchip which sends an individual number to the immobilizer system in the car to verify the identity of the key. This adds an additional layer of security that greatly reduces the risk of theft and other forms of vehicle crime. Transponder keys, as with any other electronic device, are prone to various problems, including those relating to the chip's function.
Transponder chips can be delicate and even a minor physical injury can affect their ability to work. It is crucial to examine your transponder keys to see if there are signs of wear, as these can be the reason for a malfunctioning immobiliser.
Additionally the internal microchip that is in the transponder key is sensitive to water and other environmental conditions, which may interfere with its ability to communicate correctly with a vehicle's immobilizer system. Therefore, it is important to keep the key fob as far from water as you can.
It's also important to keep in mind that a transponder key is specifically programmed to a specific vehicle, and modifying any part that is sensitive can lead to compatibility issues that could affect the functionality of the key. As a result, it's recommended to avoid any type modification to a car key, unless you have the proper expertise and equipment to perform the task safely and efficiently.
Fortunately, if you've got a key that is in need of repair or replacement, an experienced locksmith can help you out. They can duplicate your key, or create a brand new one, and program it to match the immobilizer system of your vehicle, making sure it is working correctly. This process is not like copying a metal car key. It requires specialized tools to ensure the software is programmed with the proper information.
Faulty Antenna or Receiver
The transponder chip inside your car key sends signals to the ECU that lets it determine whether or not the key is the right one to start the car. The immobiliser will stop the engine from running in the event that it isn't the correct key. This is a way to prevent thieves from using stolen or counterfeit keys to gain access to your vehicle's motor.

This could be due to a variety of causes which include an antenna that isn't compatible or an electrical interference issue. Radio frequency interference (RFI) can be caused by transmitters and communications equipment such as computer systems, cable television systems and digital devices, as well as heavy electrical equipment or lighting systems. The coaxial antenna cable may be damaged or disconnected. This can happen when pets run around the house or the cable is bent or pinched during installation.
The receiver might be too far from the antenna. Connect the receiver to another antenna and then check. If the error message is still present it is possible that you need to replace the antenna or reroute the coaxial cable.
Antennas do not really fail however they may get bent or pinched, or loose from the connector, which may cause the RF level to drop. Check if there is anything between the receiver and antenna, like a surge protector, splitter, or splitter, which could affect the signal strength.
If you choose to use the EEPROM method to program a car key, you'll have to remove specific modules (security components) from your vehicle and then read the "password" from them. This requires a great deal of expertise, since there is a possibility that the information can be damaged. A professional auto locksmith has a comprehensive knowledge of the circuit board and can minimize the chance of this happening by reading the data directly from the module using a specific tool.
Faulty Electronics
Many modern cars have security systems that prevent them from starting the engine in the event that they don't have a car key or remote. These systems use RFID (Radio Frequency Identification) or immobiliser controls to authenticate a fob or a key that is put into the ignition. It's a great way to reduce car crime, but it can also be a problem.
If the security light is not flashing across your dashboard, this means that the immobiliser inside your car isn't receiving the signal from the fob or key. This can be due to a number of factors, such as a battery that is depleted in the fob or a physical damage to the key. If visit the website are experiencing this problem follow the instructions provided by the manufacturer to reset the system or consult a professional for help.
When you insert the transponder chip in your key, it sends a code to your car's immobiliser system which is then compared to codes stored in the computer. If the codes are the identical, the engine will be turned on and the immobiliser shuts off. If the immobiliser is unable to detect the signal it will not start and you could be stuck.
There are a myriad of issues that can cause the car's immobiliser to stop functioning properly, but most of them are relatively easy and inexpensive to address. The most common cause is a dying or dead key fob battery, which can be quickly diagnosed with a simple diagnostic test. If this does not solve the issue, it could be that there are other issues with the electrical system in your car that are impacting the functioning of the immobiliser.
