An Intermediate Guide For Car Key Immobiliser Repair
Car Immobiliser Repair
In the latter half of the 20th century, automakers began to use immobilisers for cars because hot-wiring was becoming more popular among thieves. The immobiliser blocks your car's engine from starting in the event that the chip inside your key fob is damaged or does not meet.
It is crucial to repair your car key immobiliser immediately if it starts to fail or is damaged. Here are a few common reasons for the immobiliser in your car not being able to work:
Dead Batteries
A dead battery is one of the most frequently cited causes of key fob issues. Problems with batteries can be caused by long-term use, harsh environmental conditions or ageing. When a battery is damaged, it will no longer provide the power necessary to control the key fob, and also transmit the signal needed by the immobiliser system. This can prevent the car from starting, which results in the requirement for a professional technician to complete an immobiliser system repair.
In most cases, a simple battery replacement can bring back a dead one. You can purchase a good quality coin-styled batteries at your local hardware store, or even from some general retailers, for around $5-10. Once you've purchased a new battery, take the old one from the fob and carefully open the case. Look for an opening or notch along the line that divides the top and bottom halves of the fob. Push the end of the screwdriver, either flathead or coin, into the slot and then work around the edges until you can open the fob. Then, you can insert the new batteries and then snap the two halves together. When you're done you can reuse the old battery at a battery collection center close to you.
If the new battery does not solve the issue, it might be a problem with the RFID system within the key fob. The majority of vehicles with an ignition system that uses a push button require that the fob be placed close to the barrel of ignition to verify its presence and send the proper 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 dealer to fix the immobiliser.
If changing the batteries does not solve the problem it's possible to disassemble the key fob to look for buttons that are out of place or damaged. It's common that buttons become misaligned over time, as your key fob is likely to be tossed around frequently.
Key to the transponder is not working properly.
A damaged transponder key is an unfortunate occurrence that can have serious consequences. Transponder keys are different from the traditional keys made of metal that engage the ignition mechanically. They have an electronic microchip that sends a unique number to the immobilizer system of the car to confirm its identity. This adds an additional layer of security that greatly reduces the chance of theft as well as other types of crime committed by vehicles. However, just like any other electronic device transponder keys are subject to a variety of problems which include those that concern the chip's function.
Transponder chips are delicate and even a tiny amount of physical damage could affect their ability to function. It's vital to inspect your transponder keys for signs that indicate wear, as these can be the reason for an immobiliser that is not working properly.
The microchip inside transponders are also sensitive to moisture and other environmental conditions. This could affect the ability of keys to communicate with an immobilizer system. Therefore, it is important to keep your key fob and key chain away from a variety of contaminants and water as much as possible.
It is important to keep in mind that a transponder car key is programmed specifically for a specific vehicle. Changing any sensitive parts could result in compatibility issues which could impact its functionality.

This process isn't as simple as simply replicating a key from a car. It requires special tools to ensure that the software is programmed with the correct information.
Receivers or Antennas that are not working properly
The transponder chip inside the car key sends signals that are recognized by the ECU to ensure that it is the correct key that can start the vehicle. The immobiliser stops the engine from starting when it's not the right key. This is to prevent thieves from accessing your car's engine by using a stolen or copied keys.
If the signal isn't recognized by the ECU due to a fault with the antenna or receiver the car won't start. A professional auto locksmith will help you resolve these issues.

Another reason that the antenna may not be working is because the receiver may be too far from the antenna. You can check this by connecting the receiver to a different antenna. If the error message persists it is possible that you need to replace the antenna or redirect the coaxial cable.
Antennas aren't necessarily damaged however they may get twisted or pinched or they might come loose from the connector, which can cause the RF level to decrease. Also, you should check if there is any equipment installed between the antenna and the receiver, for instance a surge protector or splitter, because this could impact the strength of the signal.
If the EEPROM programming method is used to program a new car key, it involves extracting specific modules from your car (security components) and reading the "password" and stored information from them. This requires a great deal of expertise, since there is a chance that the data may be damaged. A professional auto locksmith has a thorough understanding of the circuit board and can minimise this risk by reading the data directly from the module using a special tool.
Faulty Electronics
Many modern vehicles are equipped with security systems that prevent the engine from starting if the car fob or key aren't present.

It's a great way to curb the crime in vehicles however, it could also be a problem.
If the security light on your dashboard is solid, it indicates that the car immobiliser isn't accepting the signal from the fob or key.

If car key repair service experiencing this issue Follow the manufacturer's guidelines to perform a reset on the system, or contact a professional mechanic to get help.
When you put the transponder chip inside your key, it transmits an encoded code to the immobiliser system in your car that is then compared to codes stored in the computer. If the codes match, identical, the engine will turn on and the immobiliser will turn off. If the immobiliser isn't able to detect the signal, it will prevent the engine from turning and may cause you to be stuck in a strange location.
