If a battery fails in its function, it will not transmit the signal required by the immobiliser to operate the key fob. This could stop the car from starting, resulting in the requirement for a professional technician to complete an repair to the immobiliser system.

Most times replacing the battery is all you need to revive a dead battery and get it back to working. A good quality coin-style battery can be found at your local hardware store or even some general retailers for between $5-10. Once you've purchased a new battery, remove the old one from the fob, and carefully open the case. There's a slot or notch along the seam that separates the bottom and top halves.

When you're done your work, you can reuse the old battery at a nearby collection site.

If the new battery does not fix the problem, there may be an issue with the RFID system within the key fob. Most vehicles with a push-button ignition design require the fob to be positioned close to the barrel of ignition to verify its presence and send the correct signal for the vehicle to start. If the RFID on the key fob is not able to communicate with the vehicle, you will be required to have a replacement key made or take it to a dealership to fix the immobiliser.

Key for transponder not working

A transponder key that's not working can have serious consequences. Unlike traditional metal keys, that mechanically engage the ignition, a transponder key is equipped with an electronic microchip which transmits an individual code to the car's immobilizer system, which confirms its identity prior to allowing it to start the engine. This adds a layer of security, decreasing the possibility of thefts as well as other vehicular crimes. Transponder keys, as with any electronic device, are prone to various problems that are related to the chip's function.

Transponder chips can be delicate and even a minor physical damage will affect their capacity to function. It is essential to check your transponder keys to see if there are signs of wear, as they could be the reason for an immobiliser that is not working properly.

Additionally the internal microchip that is in the transponder key is sensitive to water and other environmental conditions, which can also affect its ability to communicate with the immobilizer system of a vehicle. It is therefore essential to keep the key fob and the keychain as far away from water as is possible.

It's also important to note that a transponder is specifically programmed for a specific vehicle, and changing any of the parts that are sensitive could cause compatibility issues that can affect its function. It is best to avoid making any modifications to the key unless you are equipped with the right expertise and equipment.

The coaxial antenna cable may have been damaged or disconnected. This can occur when pets roam around the house or the cable is bent or damaged during installation.

Another reason the antenna might not be functioning is that the receiver may be too far away from the antenna. You can check this by connecting the receiver to another antenna. If the error message remains, you might require a new antenna or change the coaxial cable.

Antennas don't really go bad however they may get bent or pinched, or loose from the connector, which may cause the RF level to decrease. Also, you should check if there is any equipment installed between the antenna and the receiver, like a surge protector or splitter, as this may impact the strength of the signal.

If the EEPROM programming method is employed to program a new car key, it will require the removal of specific components from your car (security components) and reading the "password" and stored information from them. This requires expertise as the information could be corrupted. A professional auto locksmith has a comprehensive knowledge of the circuit board and can minimize this risk by reading the data directly from the module using an instrument that is specifically designed for this purpose.

Faulty Electronics
