This adds an extra layer of security, reducing the chance of thefts and other vehicular crimes. However, just like any other electronic device transponder keys are prone to a variety of problems that are related to the functionality of the chip.

Transponder chips are delicate and even a small amount of physical damage could significantly impact their ability to function. It's vital to inspect your transponder keys for signs of wear, as these can be the reason for an immobiliser malfunction.

The microchip in the internal circuit of transponders are also sensitive to environmental and moisture conditions. This could affect the ability of keys to communicate with an immobilizer system.

Receivers or Antennas that are not working properly

The transponder chip in the car key sends an electronic signal that is interpreted by the ECU to verify that it is the correct key to start the 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 counterfeit keys to gain access to your vehicle's motor.

The receiver might be too far from the antenna. Connect the receiver to a different antenna and then check. If the error message is still present, you might require a new antenna or reroute the coaxial cable.

Antennas are not bad, but they can be pinched, twisted, or come loose from their connectors, causing the RF level of the signal to drop. It is also important to determine if there is any equipment installed between the antenna and the receiver, such as a surge protector or splitter because this could affect the signal strength.

If the EEPROM programming method is used to program a new car key, it will require the removal of specific components from your car (security components) and then reading the "password" and other stored information from them.
