When a battery dies, it will no longer provide the power required to control the key fob, and also transmit the signal needed by the immobiliser system. This can prevent the vehicle from starting, resulting in the need for a professional to carry out an repair to the immobiliser system.

In the majority of instances, a simple battery replacement will revive the battery that was dead. A high-quality coin-style battery can be purchased at a local hardware shop or at some general retailers for between $5-10. After you've bought a new battery, take the old one from the fob and carefully open the case. Look for a slot or notch along the seam that separates the top and bottom halves of the fob. Push the tip of an flathead screwdriver or coin into the slot, then work your way around the edges. Then, you can insert the new batteries and then snap the two halves together. When you're done recycling the old battery at a nearby battery collection site.

If the new battery fails to solve the issue, it might be a problem with the RFID system inside the key fob. In most vehicles that feature push-button ignition, the fob is required to be positioned close to the ignition barrel to verify its presence. If the RFID inside the key fob isn't able to connect with the vehicle, you'll need to get the key made specifically for your vehicle, or take it to a dealer for an immobiliser repair.

They feature an electronic microchip that transmits an individual number to the immobilizer system of the vehicle to confirm its identity. This adds a layer of security, decreasing the risk of thefts and other crimes committed by vehicles. Transponder keys, like any electronic device, are prone to a variety of issues that are related to the chip's purpose.

Transponder chips can be delicate and even a minor physical damage can impact their ability to work. This is the reason it's essential to check your transponder key for signs of wear and tear because any damage that occurs could be the direct cause of a malfunctioning car immobiliser.

In addition the internal microchip inside the transponder key is sensitive to water and other environmental conditions, which could interfere with its ability to communicate correctly with the immobilizer system of a vehicle. As a result, it is essential to keep your key fob and key chain safe from any water or other contaminants as much as possible.

It's also important to remember that a transponder key is specifically programmed for a specific vehicle, and modifying any part that is sensitive can lead to issues with compatibility that could impact the functionality of the key.

This isn't as easy as copying a regular car key made of metal. it requires the use of specific tools to ensure that the right information is entered into the software.

Faulty Receiver or Antenna

The transponder chip that is in your car key sends a signal that is recognised by the ECU to ensure that it's the right key that can start the vehicle.

The receiver could be too far from the antenna. Connect the receiver to a different antenna and test. If the error message persists it is possible that you require a new antenna or reroute your coaxial cable.

Antennas aren't necessarily bad, but can be twisted, pinched or detached from their connectors, which can cause the RF quality of the signal to drop. Examine if there's anything between the antenna and receiver such as a surge protector, splitter, or splitter that could impact the strength of the signal.

If you use the EEPROM method to program the car key, you will have to remove specific modules (security components) from your vehicle and then read the "password" from them. This requires expertise as the data could be damaged. A professional auto locksmith has a comprehensive understanding of the circuit board and can minimise this risk by reading the data directly from the module using an instrument that is specifically designed for this purpose.
