Key to the Transponder is not working.
A faulty transponder key is an unfortunate incident that could result in serious consequences. Transponder keys differ from traditional metal keys that engage the ignition mechanically. They feature an electronic microchip that sends an individual number to the immobilizer system of the car to verify the identity of the key. This adds an extra layer of security, reducing the chance of thefts and other vehicular crimes. Transponder keys, as with any other electronic device, are prone to various issues, including those relating to the function of the chip.
Transponder chips are delicate and even a minor physical damage will affect their ability to work. This is the reason it's essential to regularly check 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 a transponder is also sensitive to humidity and other environmental conditions. This could affect the ability of the key to communicate with an immobilizer system. Therefore, it is important to keep the key fob and keychain as far away from water as possible.

Faulty Receiver or Antenna
The transponder chip that is in your car key transmits signals that are recognized by the ECU to verify that it is the correct key to start the car. If it's not the correct key, the immobiliser system will stop the engine from starting. This is a way to prevent thieves from using stolen or counterfeit keys to gain access to your car's motor.

Antennas aren't bad, but can be twisted, pinched, or come loose from their connectors, causing the RF level of the signal to decrease. It is also important to determine if there is any equipment between the antenna and the receiver, such as a surge protector or splitter since this can influence the signal strength.
If the EEPROM programming method is used to program a new car key, it will require the removal of specific modules from your vehicle (security components) and then reading the "password" and stored information from them.

If the codes coincide the engine will begin and the immobiliser will turn off. If the immobiliser doesn't detect the signal, it'll stop the engine from turning over and could cause you to be stuck in a secluded location.
