Car Immobiliser Repair
In the latter half of the 20th century automakers began using immobilisers for cars because hot-wiring was becoming more popular among thieves. The immobiliser prevents your car's engine from starting when the chip in your key fob has been damaged or does not meet.
This is why it's essential to get your car's key immobiliser repair done promptly if it's malfunctioning or broken. Here are a few most common reasons for the immobiliser on your car not working:

A dead battery is one of the most frequently cited causes of key fob problems. A battery can go bad through prolonged use, exposure to harsh environmental conditions, or simply aging. When a battery is damaged and is no longer able to provide the power necessary to operate the key fob and transmit the signal needed by the immobiliser system. This can prevent the vehicle from starting, resulting in the requirement for a professional to carry out an immobiliser system repair.
Most of the time replacing the battery is all that is required to revive an old battery and get it working again. A good coin-style battery can be found at a local hardware shop or even some general retailers for between $5-10. Once you've purchased a brand new battery, remove the old one from the fob and then carefully open the case. You'll find an opening 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 batteries and snap the two halves together. Once you are done you can reuse the old battery at a collection site close to you.
If the new battery doesn't fix the problem, there might be a problem with the RFID system within the key fob. Most vehicles that have the push-button ignition feature require the fob to be placed close to the barrel of ignition to verify its presence and send the right signal for the vehicle to start. If the RFID on the key fob cannot communicate with the vehicle, you will be required to have a replacement key or take it to a dealership to fix the immobiliser.
If changing the batteries doesn't solve the issue You may need to take the key fob apart to look for buttons that are not in place or damaged. It's normal that buttons become misaligned over time, as your key fob is bound to be jostled around a lot.
Key to the Transponder is not working.
A faulty transponder key is an unfortunate occurrence that can cause serious damage. Transponder keys are different from conventional keys made of metal, which engage the ignition mechanically. remote car key repair feature an electronic microchip that transmits an unique number to the immobilizer system of the vehicle to verify the identity of the key. This adds an extra layer of security, which reduces the chance of thefts and other crimes committed by vehicles. Transponder keys, as with any electronic device, are susceptible to various issues that are related to the function of the chip.
Transponder chips can be fragile and even a minor physical damage can impact their capability to function. It is essential to check your transponder keys for signs of wear, as these can be the reason for an immobiliser that is not working properly.
Additionally the internal microchip that is in a transponder key is also sensitive to water and other environmental conditions, which could hinder the ability of it to communicate with a vehicle's immobilizer system. It is therefore essential to keep the key fob as far away from water as you can.
It's also important to remember that a transponder is specifically programmed to a specific vehicle, and changing any of the parts that are sensitive could lead to compatibility issues that can affect the functionality of the key. Therefore, it's recommended to avoid any type modification to a car key as long as you have the skills and tools to do it safely and effectively.

A faulty Receiver or Antenna
The transponder chip on your car key transmits an electrical signal to the ECU that allows it to verify whether the key is the right one to start the vehicle. If it's not the correct key, the immobiliser system will stop the engine from starting. This is to stop thieves from using stolen or cloned keys to access your car's motor.

Radio frequency interference could be caused by heavy electrical equipment lighting systems, computers, digital devices cable television systems, and transmitters. The coaxial antenna cable might have been damaged or cut off. This could happen when your pets run around in the house, or if your cable is twisted during installation.
The receiver could be too far from the antenna. You can test this by connecting the receiver to another antenna. If the error message persists it is possible that you require an additional antenna or change the route of your coaxial cable.
Antennas do not really fail, but they can get bent or pinched, or even loosen from the connector, which can cause the RF levels to drop. Make sure there's nothing between the antenna and receiver such as a surge protector, splitter, or splitter, that could affect the strength of the signal.
If the EEPROM programming method is used to program a new car key, it involves the removal of specific modules from your car (security components) and reading the "password" and other stored information from them. This requires a great deal of expertise, since there is a risk that the data may be damaged. A professional auto locksmith can minimise the risk by reading information directly from the module with a specific tool.
Faulty Electronics

If you're experiencing this issue, follow the manufacturer's instructions to perform a reset on the system, or call an expert mechanic for assistance.
When you insert the transponder into your key, the chip transmits an immobiliser system in the car. This code is then examined against the codes that are stored on the computer. If the codes match, same, the engine will turn on and the immobiliser shuts off. If the immobiliser doesn't detect the signal, it'll stop the engine from turning and may leave you stuck in a secluded area.
