If a battery fails in its function, it will not transmit the signal required by the immobiliser and operate the key fob.

Faulty transponder key
A defective transponder key can be an unfortunate incident that could result in serious consequences. Contrary to traditional keys made of metal that mechanically engage the ignition keys, transponder keys are equipped with an electronic microchip that sends an unique code to the car's immobilizer system, which confirms its identity before allowing it to start the engine. This adds an additional layer of security that significantly reduces the chance of theft and other types of vehicle crime. However, as with any other electronic device, transponder keys are susceptible to a variety of problems that are related to the functionality of the chip.
Transponder chips can be delicate and even a minor physical injury can affect their ability to work. It's vital to inspect your transponder keys for signs that indicate wear, as these can be the cause of a malfunctioning immobiliser.
In addition, the internal microchip in a transponder key is also sensitive to water and other environmental conditions, which may affect the ability of it to communicate with the immobilizer system of a vehicle. As a result, it is important to keep your key fob and key chain away from water and other contaminants as much as possible.
It's important to remember that transponder keys are designed specifically for a particular vehicle.

A faulty Receiver or Antenna
The transponder chip inside your car key transmits a signal that is recognised by the ECU to verify that it's the right key to start the car. The immobiliser stops the engine from starting in the event that it isn't the correct key. This is to deter thieves from using stolen or duplicate keys to access your car's motor.

Antennas aren't necessarily damaged however they may get bent or pinched, or even loosen from the connector, which may cause the RF level to decrease. Examine if there's anything between the antenna and receiver such as a surge protector, splitter or splitter, that could affect the signal strength.
If you are using the EEPROM method to program a car key, you will need to extract specific modules (security components) from your vehicle and then read the "password" from them. This requires a great deal of knowledge, as there is a risk that the information can be damaged. A professional auto locksmith can minimise the risk by reading data directly from the module an instrument that is specifically designed for this purpose.
Faulty Electronics
Many modern cars are fitted with security systems that block the engine from beginning if the car's ignition key or fob isn't present. These systems make use of transponder chips, RFID (Radio-Frequency Identification) technology, or immobiliser control units to authenticate the keys or fob after it is put into the ignition.

When you insert your transponder into your key, the chip transmits a signal to the immobiliser system of your car. The code is examined against the codes that are stored on the computer. If the codes match then the engine will start and the immobiliser will turn off. If the immobiliser is unable to detect the signal, the engine will not start and you could be trapped.
Many problems can cause the immobiliser of your vehicle to cease working properly. However, most of them are easy and inexpensive to repair. The most common cause is a dying or dead key fob battery which can be identified by a quick diagnostic test.
