Key to the Transponder is not working.

A transponder key that's not working can result in serious consequences. Transponder keys are different from the traditional keys made of metal that engage the ignition mechanically. They have 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 possibility of theft and other forms of crime committed by vehicles. Transponder keys, like any other electronic device, are susceptible to various issues related to the function of the chip.

Transponder chips are fragile and even a tiny amount of physical damage could significantly impact their ability to function. This is why it's important to regularly inspect the transponder chip for signs of wear and tear as any such damage can be a direct cause for malfunctioning car immobiliser.

The microchip in the internal circuit of transponders is also sensitive to humidity and other environmental conditions. This can interfere with the ability of a key to communicate with an immobilizer system. Therefore, it is essential to keep your key fob and key chain free from water and other contaminants as much as possible.

It's also important to keep in mind that a transponder is specifically programmed to a specific vehicle, and modifying any sensitive parts can result in issues with compatibility that could impact the functionality of the key. It is recommended to not make any modifications to a key unless you're equipped with the right expertise and equipment.

This isn't as easy as copying a standard car key made of metal. it requires the use of specialized tools to ensure that all of the proper information is entered into the software.

Antenna or Receiver is damaged.

The transponder chip on your car key transmits signals to the ECU that allows it to determine whether it is the right one to start the car. If it isn't the correct key, the immobiliser system will stop the engine from starting. This is to deter thieves from using stolen or cloned keys to gain access to your vehicle's motor.

If the signal isn't recognized by the ECU because of a problem with the antenna or receiver the car won't start. A professional auto locksmith will assist you in resolving these issues.

It's also possible that the coaxial antenna cable has been damaged or broken. This could happen when your pets run around in the house, or if the cable is twisted during installation.

The receiver could be too far away from the antenna. You can check this by connecting the receiver to another antenna. If the error message is still present it is possible that you require an additional antenna or change the route of your coaxial cable.

Antennas are not good, but they could be pinched, twisted or detached from their connectors, which can cause the RF strength of the signal to decrease. You should also check whether there is any equipment between the antenna and the receiver, such as 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 car (security components) and reading the "password" and stored data from them. This requires a lot of knowledge, as there is a possibility that the information can be damaged.
