If a battery fails it will not provide the power necessary to control the key fob, and also transmit the signal required by the immobiliser system. This can prevent the car from starting, which results in the requirement for a professional to carry out an immobiliser system repair key fob.

In most cases, a simple battery replacement can bring back an old one. You can purchase a top quality coin-styled battery at your local hardware store or even from a few general retailers for around $5-10.

Key for transponder not working

A transponder key that is faulty could have severe consequences. In contrast to traditional keys made of metal, that mechanically engage the ignition, a transponder key is equipped with an electronic microchip that transmits a unique code to the car's immobilizer system to verify its identity prior to allowing it to start the engine. This adds a layer of security, decreasing the chance of thefts and other vehicular crimes. Transponder keys, like any other electronic device, are susceptible to various issues related to the chip's purpose.

Transponder chips are delicate and even a tiny amount of physical damage can severely affect their capacity to function. This is why it's crucial to regularly check your transponder key for signs of wear and tear, as any such damage can be a direct cause for an immobiliser malfunctioning in your car.

The microchip in the internal circuit of a transponder is also sensitive to humidity and other environmental conditions. This can interfere with the ability of the key to communicate with an immobilizer system. As a result, it is essential to keep your key fob and key chain safe from water and other contaminants as much as you can.

It's important to remember that the transponder car key is designed specifically for a particular vehicle.

They can duplicate your key or create a brand new one, and program it to match the immobilizer system of your vehicle, making sure it functions correctly. This isn't as straightforward as copying a standard metal car key, and it requires specific tools to ensure that all of the correct details are entered into the software.

Antenna or Receiver that is not working properly

The transponder chip in your car key sends a signal to the ECU that lets it determine whether it is the right one to start the vehicle. The immobiliser prevents the engine from starting in the event that it isn't the correct key. This is done to prevent thieves from gaining access to your car's engine by using a stolen or copied key.

However, if the signal doesn't reach the ECU due to an issue with the antenna or receiver, your car won't start. A professional auto locksmith will help you resolve these issues.

This could be due to a variety of causes, including an incompatible antenna or an electrical interference issue. Radio frequency interference (RFI) can be caused by communication equipment and transmitters including cable television systems, computers and digital devices, heavy electrical equipment or lighting systems. It's also possible that a coaxial antenna cable is damaged or disconnected. This can occur when pets roam around the house, or if the cable is bent or damaged during installation.

The receiver might be too far away from the antenna. You can test this by connecting the receiver to a different antenna. If the error message continues, you may require a new antenna or reroute your coaxial cable.

Antennas aren't necessarily good, but they could be twisted, pinched or detached from their connectors, causing the RF quality of the signal to decrease. Make sure there's nothing between the receiver and antenna, like a surge protector, splitter, or splitter, which could affect the signal strength.

If you choose to use the EEPROM method to program the car key, you'll need to extract specific modules (security components) from your vehicle and then read the "password" from them. This requires a lot of expertise, since there is a possibility that the data may be damaged. A professional auto locksmith can minimize the chance of this happening by reading data directly from the module using an instrument that is specifically designed for this purpose.

Faulty Electronics

Many modern cars come with security systems that prevent them from starting the engine when they don't have the remote or car key. These systems use transponder chips, RFID (Radio-Frequency Identification) technology, or immobiliser control units to authenticate the keys or fob once it's put into the ignition. It can be an effective way to reduce car crime however, it could also be a problem.

This could be due to a variety of reasons, including a battery that is depleted in the fob or a physical damage on the key. If you're experiencing this problem follow the instructions of the manufacturer to reset the system or contact a professional for assistance.

When you insert the transponder chip in your key, it transmits a code to the car's immobiliser system which is then compared with the codes stored in the computer. If the codes are the identical the engine will start and the immobiliser will shut off. If the immobiliser isn't able to detect the signal, it will stop the engine from turning and could leave you stuck in a remote location.
