Car Immobiliser Repair
In the latter half of the 20th century automakers began using car immobilisers because hot-wiring was becoming more popular among thieves. The immobiliser blocks the engine of your car from starting if the chip inside your key fob is damaged or doesn't match.
It is therefore essential to repair your car key immobiliser immediately if it is damaged or malfunctions. Here are a few most common reasons for the immobiliser on your car not working:
Dead Batteries
A dead battery is one of the most frequent reasons for key fob issues. Problems with batteries can be caused by long-term use, harsh environmental conditions or getting older. When a battery dies and is no longer able to supply the power needed to operate the key fob, and also transmit the signal needed by the immobiliser system. This can stop your vehicle from starting and may require a professional to fix the immobiliser system.
In the majority of instances, a simple battery replacement will bring back an old one. A good quality coin-style battery can be purchased at a local hardware store or even some general retailers for between $5-10. When you purchase the new battery, carefully take the old one off and then open the case. Find slots or notch on the line that divides the top and bottom halves of the fob. Push the tip of a flathead screwdriver, coin or flathead screwdriver into the slot, then move it around the edges. Then, insert the new battery and then snap the two halves of the fob closed. When you're done you can reuse the old battery at a collection facility close to you.
If the new battery does not fix the problem, there might be a problem with the RFID system within the key fob. In the majority of vehicles that have push-button ignition, the fob must be placed close to the ignition barrel to verify its presence. If the RFID in the key fob isn't able to connect with the vehicle, you'll need to make a key specifically for your vehicle, or take it to the dealer to have an immobiliser repaired.
If changing the battery doesn't resolve the problem it's worth taking the key fob apart and examining the buttons that seem to be out of place or broken. It's normal for buttons to become dislocated over time, since your key fob is bound to be tossed around frequently.
Key for transponder not working
A transponder key that is faulty could have severe consequences. Transponder keys differ from conventional keys made of metal, which engage the ignition mechanically. They are equipped with an electronic microchip that sends an individual number to the immobilizer system of the vehicle to confirm its identity. This adds an additional layer of security that greatly reduces the risk of theft and other types of vehicular crime. Transponder keys, like any electronic device, are vulnerable to various problems, including those relating to the function of the chip.
Transponder chips can be delicate and even a small physical damage will affect their ability to work. It's vital to inspect your transponder keys for signs of wear, as these can be the reason for an immobiliser that is not working properly.
In addition, the internal microchip in a transponder key is also sensitive to environmental and water conditions, which could affect its ability to communicate correctly with the immobilizer system of a vehicle. It is therefore essential to keep the key fob as far from water as you can.
It is important to keep in mind that transponder keys are designed specifically for a particular vehicle. Changing any sensitive parts could result in compatibility issues that could compromise its function. It is best to avoid making any modifications to a key unless you're equipped with the appropriate knowledge and equipment.
A professional locksmith can help you if your key requires to be replaced or repaired. They can duplicate your key, or create a brand new one, and program it to match the immobilizer mechanism of your vehicle, making sure it is working in a proper manner. This process is not as easy as copying a car key made of metal. It requires specialized tools to ensure that the software is programmed with the proper information.
automotive key repair or Receiver that is not working properly
The transponder chip inside the key of your car transmits signals to the ECU that allows it to verify whether or not it is the right one to start your vehicle. If it's not then the immobiliser will prevent the engine from starting. This is a way to prevent thieves from using stolen or duplicate keys to gain access to your vehicle's motor.
However, if the signal fails to reach the ECU due to a problem with the receiver or antenna the car won't begin. A professional auto locksmith can assist you in resolving these issues.

Radio frequency interference (RFI) can be caused by communication equipment and transmitters such as computer systems, cable television systems and digital devices, as well as heavy electrical equipment or lighting systems. It is also possible that the coaxial antenna cable has been damaged or broken. This could happen if your pets play around the home, or if the cable is damaged during installation.
The receiver could be too far away from the antenna. Connect the receiver to another antenna and then check. If the error message remains it is possible that you need to install a better antenna or redirect the coaxial cable.
Antennas do not really fail however they could be twisted or pinched or even loosen from the connector, which can cause the RF level to decrease. 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 requires the removal of specific components from your car (security components) and then reading the "password" and other stored data from them. This requires a great deal of expertise, since there is a chance that the data may be damaged. A professional auto locksmith has a comprehensive knowledge of the circuit board and can reduce the chance of this happening by reading the data directly from the module with a specific tool.
Faulty Electronics
Many modern cars come with security systems that stop them from starting the engine in the event that they don't have a car key or remote. These systems employ transponder chips, RFID (Radio-Frequency Identification) technology or immobiliser control units to authenticate the keys or fob once it's placed in the ignition. This can be a great way to reduce vehicle theft however, as with any other piece of technology, it's not always guaranteed to be a bit faulty.

If the codes coincide then the engine will start and the immobiliser will turn off. If the immobiliser doesn't detect the signal, it'll stop the engine from turning and can leave you stranded in a secluded area.
