This adds a layer of security that significantly reduces the possibility of theft and other types of crime committed by vehicles. Transponder keys, just like any other electronic device, are susceptible to a variety of issues related to the chip's function.

It's also important to keep in mind that a transponder key is specifically programmed to a specific vehicle, and altering any sensitive parts can cause compatibility issues that can affect the functionality of the key.

Antenna or Receiver is damaged.
The transponder chip that is in your car key sends a signal that is recognised by the ECU to ensure that it is the correct key that can start the vehicle.
