Car Immobiliser Repair
In the late 20th century, automakers began to use immobilisers for cars because hot-wiring was becoming more popular with thieves. The immobiliser stops your vehicle from starting if your key fob chip is damaged or doesn't match.
It is therefore important to repair your car key immobiliser as soon as it becomes faulty or damaged. Here are some of the common causes 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 from long-term usage, exposure to harsh environmental conditions, or simply ageing. When a battery fails to function, it is unable to transmit the signal required by the immobiliser and operate the key fob. This can prevent the car from starting, resulting in the need for a professional to carry out an immobiliser system repair.
In most instances, a simple battery replacement will bring back the battery that was dead. You can buy a high quality coin-styled batteries at your local hardware store, or even from some general retailers, for $5-10. After purchasing the latest coin-style battery remove the old one and then open the case. You'll find a slot or notch along the seam that separates the top and bottom halves. Then, insert the tip of a flathead screwdriver or coin into the slot, and then move it around the edges. Then, you can insert the new battery and snap the two halves of the fob together. After you've completed the process recycling the old battery at a nearby battery collection site.
If the new battery fails to fix the problem, there may be an issue with the RFID system inside the key fob. In the majority of vehicles that have ignition that is push-button, the fob is required to be positioned close to the barrel of ignition to confirm its existence. If the RFID inside the key fob cannot communicate with the vehicle, you'll need to have a new key made or take it to a dealership to fix the immobiliser.
If changing the battery does not resolve the problem, it may be worth taking the key fob apart and examining any buttons that seem to be not in the right place or are damaged. It's common for buttons to become out of alignment over time, because your key fob is likely be jostled around a lot.
Faulty transponder key
A damaged transponder key is an unfortunate occurrence that can have serious consequences. Transponder keys differ from traditional metal keys that engage the ignition mechanically. They have 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 that significantly reduces the possibility of theft and other types of crime committed by vehicles. However, as with her latest blog transponder keys are subject to a range of issues, including those related to the chip's function.
Transponder chips can be delicate and even a small physical damage can impact their capacity to function. This is why it's crucial to regularly check the transponder chip for signs of wear and tear, as any such damage can be a direct cause of a malfunctioning car immobiliser.
The internal microchip of transponders is also sensitive to moisture and other environmental conditions. This can interfere with the ability of keys to communicate with an immobilizer system. 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 is important to keep in mind that a transponder car key is programmed specifically for a specific vehicle. Modifying any of the parts that are sensitive could lead to compatibility problems that could affect its functionality. It's recommended to avoid any type of modification to a car key, unless you have the proper expertise and tools to do it safely and efficiently.
A professional locksmith can help you if your key requires to be repaired or replaced. They can duplicate your key, or create an entirely new one and program it to match the immobilizer system in your vehicle, ensuring that it functions in a proper manner. This process isn't as simple as simply copying a car key made of metal. It requires tools that are specialized to ensure that the software is programmed with the correct information.
Antenna or Receiver is damaged.
The transponder chip that is in your car key transmits a signal that is recognised by the ECU to verify that it's the right key that can start the vehicle. The immobiliser will stop the engine from starting if it's not the correct key. This is a way to prevent thieves from using stolen or cloned keys to gain access to your car's motor.
If the signal isn't able to reach the ECU due to an issue with the antenna or receiver, your car won't start. A professional auto locksmith is capable of helping you solve this problem.

It's also possible that a coaxial antenna cable has become disconnected or damaged. This could happen if your pets play around the home, or if the cable is twisted during installation.
The receiver could be too far 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 damaged, but they can get bent or pinched, or loose from the connector, which could cause the RF level to drop. It is also important to determine if there is any equipment installed between the antenna and the receiver, like a surge protector or splitter as this may affect the signal strength.
If you choose to use the EEPROM method to program the car key, you will need to extract specific modules (security components) from your vehicle and read the "password" from them. This requires a lot of expertise since the information could be corrupted. A professional auto locksmith has a comprehensive understanding of the circuit board and can minimise the risk by reading data directly from the module with a specific tool.

If the codes are the identical the engine will be turned on and the immobiliser will shut off. If the immobiliser fails to recognize the signal, it will stop the engine from turning and can leave you stranded in a remote location.
