If a battery is damaged in its function, it will not transmit the signal required by the immobiliser and operate the key fob. This could stop your vehicle from starting, and will require a professional to fix the immobiliser system.

Once you've purchased a brand new battery, take the old one from the fob and then carefully open the case. You'll find an opening or notch along the seam separating the top and bottom halves. Then, insert the end of the screwdriver, either flathead or coin, into the slot and work it around the edges to pop open the fob. Then, you can insert the new batteries and then snap the two halves together. After you've completed the process, you can recycle the old battery at a nearby collection site.

If the new battery doesn't fix the problem it could be an issue with the RFID system on the key fob itself. In most vehicles that feature push-button ignition, the fob must be held close to the ignition barrel to confirm its existence.

Key for the Transponder that isn't working

A transponder key that is faulty can have serious consequences. In contrast to traditional keys made of metal, which merely mechanically engage the ignition the transponder key is equipped with an electronic microchip that sends an unique code to the car's immobilizer system, verifying its identity before permitting it to start the engine. This adds a layer of security, decreasing the risk of thefts and other crimes committed by vehicles. Transponder keys, just like any electronic device, are susceptible to a variety of issues related to the chip's function.

Transponder chips can be fragile and even a slight physical damage can impact their capability to function. This is why it's crucial to regularly inspect your transponder key for signs of wear and tear as any such damage can be a direct cause for a malfunctioning car immobiliser.

The microchip inside a transponder is also sensitive to humidity and other environmental conditions. This could affect the ability of keys to communicate with an immobilizer system. Therefore, it is essential to keep your key fob and key chain away from water and other contaminants as much as possible.

It's also important to remember that a transponder is specifically programmed for a specific vehicle, and changing any sensitive parts can cause issues with compatibility that could impact its function.

Faulty Antenna or Receiver

Another reason why the antenna might not be working is because the receiver is far from the antenna. Connect the receiver to another antenna and test. If the error message is still present then you may need to install a better antenna or redirect the coaxial cable.

Antennas aren't bad, but they can be twisted, pinched or loose from their connectors, causing the RF strength of the signal to decrease. Also, you should check if there is any equipment between the antenna and the receiver, for instance a surge protector or splitter, as this may impact the strength of the signal.

If the EEPROM programming method is used to program a new car key, it will require the removal of specific modules from your vehicle (security components) and then reading the "password" and stored data from them. This requires expertise as the information could be corrupted. A professional auto locksmith can minimise the risk by reading data directly from the module a specific tool.

Faulty Electronics

Many modern cars come with security systems that block them from starting the engine if they don't have the remote or car key.

This can be due to a number of factors, such as a battery that is depleted in the fob or a physical damage to the key. If you're experiencing this issue follow the instructions of the manufacturer to reset the system, or call a professional mechanic to get help.

When you insert the transponder chip into your key, it sends an encoded code to the car's immobiliser system which is then compared to codes stored in the computer. If the codes match, identical the engine will start and the immobiliser will turn off. If the immobiliser fails to detect the signal it won't turn over and you may be stranded.
