Car Immobiliser Repair
In the latter half of the 20th century, automakers began to use car immobilisers because hot-wiring was becoming more popular with thieves. The immobiliser prevents your vehicle from starting if your key fob chip is damaged or doesn't match.

Dead Batteries
A dead battery is among the most common reasons for key fob issues. Battery problems can be caused by long-term use, harsh environmental conditions or the aging process. If a battery fails to function, it is unable to transmit the signal required by the immobiliser to operate the key fob. This can prevent your vehicle from starting and may need a professional repair the immobiliser system.
Most of the time, a simple replacement is all that is needed to revive an old battery and get it working again. A good quality coin-style battery can be purchased at a local hardware shop or even some general retailers for between $5-10. After purchasing the new battery, remove the old one and open the casing. Find slots or notch on the edge that separates the bottom and top halves of the fob. Then, insert the end of a coin or flathead screwdriver into the slot and work around the edges until you can open the fob. Then, insert the new batteries and snap the two halves together. Once you are done, you can recycle the old battery at a battery collection site close to you.
If the new battery doesn't solve the issue, it may be an issue with the RFID system within the key fob. In most vehicles with push-button ignition, the fob is required to be positioned close to the ignition barrel to verify its presence. If the RFID in the key fob isn't able to connect with the vehicle, you'll need to get the key made for the vehicle or bring it to the dealership for an immobiliser repair.

Key for the Transponder that isn't working
A transponder key that is defective can have serious consequences. In contrast to traditional keys made of metal, that simply mechanically activate the ignition, a transponder key is equipped with an electronic microchip that sends an unique code to the immobilizer system, verifying its identity before allowing it to start the engine. This adds a layer of security that significantly reduces the risk of theft and other forms of vehicle crime. Transponder keys, just like any electronic device, are vulnerable to various problems that are related to the function of the chip.
Transponder chips can be delicate and even a minor physical damage will affect their ability to work. It is essential to check your transponder keys to see if there are signs of wear, as these can be the reason for an immobiliser that is not working properly.
The microchip in the internal circuit of transponders is also sensitive to humidity and other environmental conditions. This can affect the ability of the key to communicate with an immobilizer system. Therefore, it is important to keep your key fob and key chain free from water and other contaminants as much as is possible.
It is important to keep in mind that a transponder car key is designed specifically for a particular vehicle.

This process isn't as simple as simply replicating a key from a car. It requires tools that are specialized to ensure that the software is programmed correctly with the proper information.
repair car key or Receiver
The transponder chip inside the key of your car transmits an electrical signal to the ECU that lets it determine whether or not the key is the right one to start your vehicle. The immobiliser prevents the engine from running in the event that it isn't the correct key. This is done to prevent thieves from accessing your car's engine using stolen or cloned key.

The coaxial antenna cable might have been damaged or cut off. This can happen when pets run around the house or when the cable is twisted or damaged during installation.
The receiver may be too far from the antenna. You can test this by connecting the receiver to another antenna. If the error message remains, you might need to install a better antenna or change the coaxial cable.
Antennas do not really fail however they could be pinched or twisted, or they might come loose from the connector, which may cause the RF level to decrease. Examine if there's anything between the receiver and antenna such as a surge protector, splitter, or splitter, which could affect the signal strength.
If the EEPROM programming method is used to program a new car key, it involves extracting specific components from your car (security components) and then reading the "password" and stored information from them. This requires a great deal of knowledge, as there is a possibility that the data may be corrupted. A professional auto locksmith will reduce the risk by reading information directly from the module using a special tool.

When you insert the transponder chip into your key, it sends a code to your car's immobiliser system which is then compared with the codes that are stored in the computer. If the codes are the same, the engine will turn on and the immobiliser will shut off. If the immobiliser isn't able to detect the signal, it will prevent the engine from turning and could cause you to be stuck in a strange area.
A variety of issues could cause the immobiliser in your vehicle to not function properly. However, most of them are simple and inexpensive to repair.
