Car Immobiliser Repair
Car immobilisers became a requirement for automakers in the latter part of the 20th century, as hot-wiring cars became increasingly popular with thieves. The immobiliser stops your car's engine from starting when the chip in your key fob has been damaged or does not match.
It is therefore important to repair your car's key immobiliser immediately if it starts to fail or is damaged. Here are a few most frequent reasons for the immobiliser on your car not working:
Dead Batteries
Key fob problems are often caused by batteries that are dead. A battery can go bad through prolonged usage, exposure to harsh environmental conditions, or simply ageing. When a battery dies, it will no longer provide the power necessary to operate the key fob, and also transmit the signal needed by the immobiliser system. This can stop your car from starting and need a professional repair the immobiliser system.
In the majority of cases, a simple battery replacement will bring back the battery that was dead. A high-quality coin-style battery can be purchased at a local hardware shop or even at a general retailer for between $5-10. After you've bought a new battery, remove the old one from the fob, and carefully open the case. Find slots or notch on the edge that separates the bottom and top halves of the fob. Then, insert the end of an screwdriver with a flathead or coin into the slot and then work around the edges to open the fob. Then, insert the new batteries and then snap the two halves together. When you're done you can reuse your old battery at a collection facility near you.
If the new battery does not fix the problem, there may be an issue with the RFID system inside the key fob. In most vehicles with ignition that is push-button, the fob must be placed close to the barrel of ignition to verify its presence. If the RFID on your key fob isn't able to connect with the vehicle, you'll have to make a key specifically for your vehicle, or take it to the dealer to have an immobiliser repaired.
If changing the battery does not resolve the problem It's worth taking the key fob apart and looking for any buttons that seem off-center or damaged. It's common for buttons to become out of alignment over time, because your key fob is likely to be tossed around a lot.
Faulty Transponder Key
A transponder key that is defective could have severe consequences. Transponder keys are different from traditional metal keys that engage the ignition mechanically. They are equipped with an electronic microchip that sends an unique number to the immobilizer system in the car to verify its identity. This adds an additional layer of security that significantly reduces the risk of theft as well as other types of vehicular crime. But, like other electronic device transponder keys are prone to a range of issues, including those related to the functionality of the chip.
Transponder chips can be delicate and even a small physical damage can impact their capability to function. It is crucial to examine your transponder keys for signs that indicate wear, since these could be the reason for a malfunctioning immobiliser.
In addition, the internal microchip in the transponder key is sensitive to water and other environmental conditions, which could affect its ability to communicate with a vehicle's immobilizer system. It is therefore essential to keep the key fob and keychain as far from water as possible.
It's also important to keep in mind that a transponder key has been specifically programmed to a specific vehicle, and altering any part that is sensitive can cause compatibility issues that could affect the functionality of the key. It is recommended to not make any modifications to a key unless you're equipped with the right expertise and equipment.

The coaxial antenna cable might have been damaged or cut off. This could happen when your pets play around the home, or if the cable is twisted during installation.
Another reason the antenna might not be working is because the receiver may be too far from the antenna. Connect the receiver to a different antenna and then check. If the error message is still present it is possible that you need to install a better antenna or redirect the coaxial cable.
Antennas aren't necessarily bad, but they can be pinched, twisted or loose from their connectors, causing the RF strength of the signal to decrease. Also, you should check if there is any equipment installed between the antenna and the receiver, such as a surge protector or splitter, because this could affect the signal strength.
If the EEPROM programming method is employed to program a new car key, it involves extracting specific components from your car (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 will minimize the chance of this happening by reading data directly from the module using a specific tool.
Faulty Electronics

If you're experiencing this issue, follow the manufacturer's instructions to perform a reset on the system, or contact an expert mechanic to get help.
When you insert the transponder chip into your key, it sends an encoded code to the immobiliser in the car which is then compared to codes that are stored in the computer. If the codes match, the engine will start and the immobiliser will turn off. If the immobiliser is unable to detect the signal that it is looking for, the engine will not turn over and you could be stuck.
