Car immobilisers became a requirement for automakers at the end of the 20th century, as hot-wiring cars became increasingly popular with thieves. The immobiliser blocks the engine of your car from starting in the event that the chip inside your key fob is damaged or does not match.

This is why it's essential to get your car's key immobiliser repair completed promptly if it's malfunctioning or broken. Here are a few typical reasons for your car's immobiliser not working: work:

Dead Batteries

A dead battery is among the most frequent reasons for key fob issues. Problems with batteries can be caused by long-term use and harsh environmental conditions as well as ageing. When a battery dies it will not supply the power needed to control the key fob and send the signal needed by the immobiliser system. This can prevent your vehicle from starting and may require a professional to repair the immobiliser system.

In most cases, a simple replacement can bring back a dead one. You can purchase a good quality coin-styled batteries at your local hardware store or even from a few general retailers, for $5-10. Once you've purchased a new battery, take the old one from the fob and carefully open the case. You'll find a slot or notch along the seam separating the top and bottom halves. Push the end of an screwdriver with a flathead or coin into the slot and work around the edges until you can open the fob. Then, insert the new batteries and then snap the two halves together. When you're done your work, you can reuse the old battery at a nearby battery collection site.

If the new battery doesn't solve the issue, it may be a problem with the RFID technology in the key fob itself. The majority of vehicles with an ignition system that uses a push button require that the fob be held up close to the barrel of ignition in order to verify its presence and send the correct signal for the vehicle to start. If the RFID inside the key fob is not able to communicate with the vehicle, you will need to have a new key made or take it to a dealership to repair the immobiliser.

If changing the batteries doesn't resolve the issue, you may want to take the key fob apart to find any buttons that are out of place or broken. Since your key fob likely gets jostled about a lot when you use it, it's not unusual for some of the buttons to get stuck or misaligned in time.

Faulty transponder key

A faulty transponder key is an unfortunate incident that could result in serious consequences. Transponder keys are different from conventional keys made of metal, which engage the ignition mechanically. They are equipped with an electronic microchip which sends an unique number to the immobilizer system in the car to confirm its identity. This adds an additional layer of security that significantly reduces the chance of theft and other types of vehicular crime. However, just like any other electronic device transponder keys are prone to a variety of problems which include those that concern the functionality of the chip.

Transponder chips are fragile, and even a small amount of physical damage could affect their ability to function. It's vital to inspect your transponder keys for signs of wear, as these can be the cause of an immobiliser that is not working properly.

The microchip in the internal circuit of transponders is also sensitive to environmental and moisture conditions. This could affect the ability of the key to communicate with an immobilizer system. It's therefore important to keep the key fob and keychain as far away from water as you can.

It's important to remember that a transponder car key is designed specifically for a particular vehicle. Modifying any of the parts that are sensitive could lead to compatibility problems that could affect its functionality. It is best to avoid making any modifications to the key unless you're equipped with the right expertise and equipment.

A professional locksmith can help you if your key requires to be replaced or repaired. They can duplicate your key or design a new one from scratch and they'll be able to program it to match your particular vehicle's immobilizer system, ensuring that it works as intended. This process isn't as simple as copying a regular car key made of metal, and it requires specialized tools to ensure that all of the correct information is entered into the software.

Antenna or Receiver is damaged.

The transponder chip inside the key of your car transmits signals to the ECU that allows it to determine whether or not the key is the correct one to start your vehicle. If it isn't the correct key, the immobiliser system will prevent the engine from beginning. This is done to prevent thieves from accessing your vehicle's engine by using a stolen or copied keys.

If the signal cannot be accepted by the ECU due to a problem with the antenna or receiver, the car will not start. A professional auto locksmith is capable of helping you solve this issue.

Radio frequency interference could be caused by electrical equipment that is heavy, lighting systems, computers, digital devices cable television systems, and transmitters. The coaxial antenna cable might have been damaged or cut off. This can occur when pets roam around the house, or if the cable is twisted or damaged during installation.

The receiver might be too far away from the antenna. You can check this by connecting the receiver to a different antenna. If the error message is still present it is possible that you need to replace the antenna or redirect the coaxial cable.

Antennas aren't bad, but can be bent, pinched or loose from their connectors, which can cause 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 influence the signal strength.

If you use the EEPROM method to program the car key, you will require the removal of specific modules (security components) from your vehicle and then read the "password" from them. This requires a lot of expertise, since there is a possibility that the data may be corrupted. A professional auto locksmith has a deep understanding of the circuit board and can minimize the chance of this happening by reading the data directly from the module using a special tool.


Faulty Electronics

Many modern vehicles are equipped with security systems that block the engine from starting if the car fob or key isn't in the car. These systems use transponder chips, RFID (Radio-Frequency Identification) technology or immobiliser control units to authenticate the key or fob once it's inserted into the ignition. It's an effective method to decrease car crime, but it can also be a disaster.

If remote car key repair is solid on your dashboard, this means that the immobiliser in your car is not receiving the signal from the fob or key.

If you're experiencing this problem follow the instructions of the manufacturer to reset the system, or consult a professional for help.

When you insert the transponder chip in your key, it sends a code to the immobiliser system in your car that is then compared with the codes that are stored in the computer. If the codes match, same the engine will turn on and the immobiliser will turn off. If the immobiliser isn't able to detect the signal, it'll stop the engine from turning and may leave you stuck in a secluded place.
