Watch Out: What Car Key Immobiliser Repair Is Taking Over And What Can We Do About It
Car Immobiliser Repair

Car immobilisers became a necessity for automakers in the late 20th century as hot-wiring vehicles became increasingly popular with thieves. The immobiliser stops the engine of your car from running in the event that the chip inside the key fob is damaged or does not match.

This means that it is crucial to get your car's key immobiliser repair done quickly when it's faulty or damaged. Here are some of the most common reasons for the immobiliser of your car not working:

Dead Batteries

Key fob problems are often caused by batteries that are dead. A battery can go bad due to long-term use, exposure to harsh environmental conditions or simply ageing. When a battery dies, it will no longer supply the power needed to operate the key fob, and also transmit the signal needed by the immobiliser system. This can stop your vehicle from starting, and will require a professional to repair the immobiliser system.

In keys repair , a simple replacement can bring back the battery that was dead. You can buy a high quality coin-styled battery from your local hardware store or even from a few general retailers, for $5-10. After purchasing a new coin-style battery, carefully take the old one off and then open the case. Look for a slot or notch along the line that divides the top and bottom halves of the fob. Then, insert the end of the screwdriver, either flathead or coin, into the slot and work it around the edges to open the fob. Then, insert the new batteries and snap the two halves together. Once you've finished, you can recycle the old battery at a nearby collection site.

If the new battery doesn't fix the problem, it may be a problem with the RFID technology in the key fob itself. In most vehicles that feature push-button ignition, the fob is required to be positioned close to the ignition barrel to verify its presence. If the RFID in the key fob does not communicate with the vehicle, you'll have to get a new key or take it to a dealership to repair the immobiliser.

If changing the battery doesn't solve the issue it's worth taking the key fob apart and looking for any buttons that seem not in the right place or are damaged. It's common for buttons to become dislocated over time, since your key fob is likely to be tossed around a lot.

Faulty transponder key

A transponder key that's not working can 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 a unique number to the immobilizer system of the vehicle to confirm its identity. This adds an additional layer of security that reduces the risk of theft as well as other types of vehicular crime. Transponder keys, like any electronic device, are vulnerable to a variety of issues that are related to the chip's function.

remote key fob repair near me can be delicate and even a slight physical injury can affect their ability to work. This is why it's crucial to check your transponder key for indications of wear and tear, because any damage that occurs could be a direct cause for an immobiliser malfunctioning in your car.

The microchip in the internal circuit of transponders is also sensitive to humidity and other environmental conditions. This can affect the ability of a key to communicate with an immobilizer system. This is why it's important to keep your key fob and key chain safe from water and other contaminants as much as is possible.

It is important to keep in mind 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 which could impact its functionality. It is recommended to not make any modifications to a key unless you are equipped with the appropriate knowledge and equipment.

If you're in the unfortunate position of having a key that is in need of repair or replacement, an expert locksmith can help you out. 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 properly. This isn't as easy as copying a regular car key made of metal. it requires specialized tools to ensure that all of the proper details are entered into the software.

A faulty Receiver or Antenna

The transponder chip in the key of your car transmits signals to the ECU that lets it determine whether or not the key is the right one to start the car. The immobiliser will stop the engine from running in the event that it isn't the correct key. This is to stop thieves from using stolen or counterfeit keys to gain access to your car's motor.


If the signal is not recognized by the ECU because of a problem with the antenna or the receiver the car won't start. A professional auto locksmith will be in a position to assist you in resolving this problem.

Radio frequency interference is caused by heavy electrical equipment lighting systems computers, computers, digital devices cable television systems, and transmitters. It is also possible that the coaxial antenna cable has been damaged or broken. This could happen when pets run around the house, or if the cable is twisted or damaged during installation.

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 is still present then you might require a new antenna or reroute your coaxial cable.

Antennas don't really go bad however they may get bent or pinched, or they might come loose from the connector, which may cause the RF levels to drop. It is also important to determine if there is any equipment installed between the antenna and the receiver, such as a surge protector or splitter, since this can affect the signal strength.

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 other stored data from them. This requires a lot of expertise since the data could be damaged. A professional auto locksmith has a deep knowledge of the circuit board and can minimise the risk by reading data directly from the module using an instrument that is specifically designed for this purpose.

Faulty Electronics

Many modern cars have security systems that stop them from starting the engine if they don't have the remote or key to the car. These systems use RFID (Radio Frequency Identification) or immobiliser controls to authenticate a fob or key that is put into the ignition. This can be a fantastic method to prevent theft of vehicles however, as with any other piece of electronic equipment, it's possible to fail.

If the security light is on across your dashboard, this means that the immobiliser in your car isn't receiving the signal from the fob or key.

If the codes coincide, the engine will start and the immobiliser shut off. If the immobiliser fails to recognize the signal, it'll stop the engine from turning and may cause you to be stuck in a remote area.
