Car Immobiliser Repair

In the late 20th century automakers began using car immobilisers due to hot-wiring becoming more popular among thieves. The immobiliser prevents the engine of your car from running when the chip in the key fob is damaged or does not match.

It is crucial to fix your car's key immobiliser as soon as it becomes faulty or damaged. Here are a few common causes of your car's immobiliser not working: function:

Dead Batteries

A dead battery is among the most frequently cited causes of key fob problems. Battery problems can be caused by prolonged use or harsh environmental conditions, or the aging process. When a battery dies it will not provide the power required to operate the key fob and send the signal required by the immobiliser system. This could stop the car from starting, which results in the requirement for a professional to perform an repair to the immobiliser system.

Most of the time an easy replacement is all you need to revive the battery that has died and make it functional again. A good quality coin-style battery is available at a local hardware shop or at 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. There's an opening or notch on the seam that separates the bottom and top halves. Use a flathead screwdriver, coin or flathead screwdriver into the slot, and then work your way around the edges. Then, you can insert the new batteries and then snap the two halves together. When you're done, you can recycle the old battery at a battery collection facility close to you.

If the new battery doesn't fix the problem it could be a problem with the RFID system in the key fob itself. The majority of vehicles with a push-button ignition design require the fob to be placed close to the ignition barrel to verify its presence and send the right signal for the vehicle to start. If the RFID inside your key fob isn't able to communicate with the car, you will need to have the key made for your vehicle or take it to the dealership to have an immobiliser repaired.

If changing the battery does not solve the issue it's worth taking the key fob apart and examining any buttons that seem off-center or damaged. Because your key fob is constantly tossed around when you use it and it's not uncommon for some of the buttons to become displaced or stuck over time.

Key to the transponder is not working properly.

A defective transponder key can be an unfortunate incident that could have serious consequences. In contrast to traditional keys made of metal, that simply mechanically activate the ignition keys, transponder keys are equipped with an electronic microchip that sends an individual code to the vehicle's immobilizer system, which confirms its identity prior to being able to start the engine. This adds a layer of security that reduces the possibility of theft and other types of vehicle crime. But, like other electronic device, transponder keys are susceptible to a myriad of issues that are 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's vital to inspect your transponder keys for signs that indicate wear, as they could be the cause of a malfunctioning immobiliser.

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

It is important to keep in mind that transponder keys are programmed specifically for a specific vehicle. Modifying any of the parts that are sensitive could cause compatibility issues which could impact its functionality.

Faulty Receiver or Antenna

The transponder chip in your car key transmits an electrical signal to the ECU that lets it determine whether or not it is the right one to start the vehicle. If it isn't the correct key, the immobiliser system will stop the engine from beginning. This is to prevent thieves from accessing your car's engine with a stolen or duplicated key.

It's also possible that a coaxial antenna cable is damaged or disconnected. This can happen when pets run around the house or when the cable is bent or pinched during installation.

The receiver may be too far from the antenna. You can check this by connecting the receiver to another antenna. If the error message persists then you might require a new antenna or reroute your coaxial cable.

Antennas aren't bad, but can be bent, pinched or detached from their connectors, causing the RF level of the signal to drop. You should also check whether there is any equipment installed between the antenna and the receiver, for instance a surge protector or splitter as this may influence the signal strength.

If the EEPROM programming method is employed to program a new car key, it requires the removal of specific components from your car (security components) and reading the "password" and other stored information from them. This requires a lot of expertise, as there is a possibility that the data may be corrupted. A professional auto locksmith will minimise the risk by reading data directly from the module using an instrument that is specifically designed for this purpose.

If you're experiencing this problem follow the instructions provided by the manufacturer to reset the system or seek help from a professional.

When you insert the transponder into your key, the chip transmits a signal to the immobiliser system in the car. This code is then examined against the codes that are stored on the computer. If the codes coincide then the engine will start and the immobiliser shut off. If the immobiliser is unable to detect the signal, the engine will not turn over and you may be stranded.

Many problems could cause the immobiliser in your car to stop working properly. However, the majority of them are simple and affordable to fix.
