If the problem persists then it could be due to electrical problems or wiring issues. If this is the case, it's best to have a professional diagnose and fix the issue.

Transponder Chip

In cars manufactured after 1995, a small electronic chip called transponder is integrated into the head of your car mobile key fob repair. Also referred to as a 'chip key' or a 'transmitter and responder mobile key fob repair, it is designed to stop the engine from starting if a third party has an exact copy of your car key. It functions by sending an audio frequency signal from the key to the immobiliser system of your car. If the code stored in the computer of the car matches the signal transmitted by the key the immobiliser will then be deactivated and the engine will start.

The key with the transponder is also referred to as a "fob" or a "smart" key due to the fact that it is more difficult to copy than mechanical keys. Utilizing specific techniques, it is feasible to duplicate a standard car key but not the transponder key. Transponder chips are powered by an infrared signal and not battery power.

To turn on the transponder, the ignition cylinder needs to be in the ON position. The ring emits a burst IR energy which is received by a microchip within the key. The chip then sends a unique code to the immobiliser in your car. The car's computer compared the code in its memory with that from the transponder chip and If they are compatible the engine will be able to start.

If the immobiliser detects that an unauthorised transponder or key is being used, it will disable the engine and prevent any of its vital components from working. Without a functioning engine, the vehicle will not be able to move and it would be very easy for criminals to hot-wire the vehicle and drive away.

If you do not take action and the security light on your vehicle will continue blinking, and you won't be able to start it.

Security Light

The immobiliser uses a small battery to transmit an electrical signal to the chip inside your key. This is an anti theft device that prevents anyone from driving your car without the correct key. If the system cannot detect a digital serial number from the chip on your key, it will shut off the engine immobiliser, which will stop the car from starting.

The car immobiliser is a fantastic way to deter thieves, however it can sometimes get out of in sync. This can be due to interference or the system is too sensitive. This could require a reset. To do this, simply disconnect the battery. It should be left disconnected for around 15 minutes before reinstalling it and begin the car. This will reset the system and make it ready to accept your key once more.

The security light is an immobiliser's way of warning you of the presence of a problem. If you try to start the car but the light is solid on it means that the chip inside your key doesn't match the code stored in the ECU. This can happen when your car's key has been replaced with an alternative key that is not programmed for the vehicle, or when an ECU was not swapped correctly.

If this is the case you should bring your transponder key or chip to a professional to get them correctly programmed for the vehicle you are driving. It's possible that the system isn't able to accept the key due to a software upgrade or glitch. To test, put your key in the ignition and turn it to the ON position. Do not try to start the vehicle. Let the key remain in this position for 10 minutes. This should cause the security light to light up and then to go off. If it doesn't, you'll have to repeat the process and wait another 10 minutes. This should solve the problem if you repeat it three times.

Programming

A car immobiliser prevents the car's engine from operating without a correctly programmed key or fob. It makes use of a unique RFID micro-chip that can't be duplicated and has its own digital serial number. The immobiliser will be disengaged if it doesn't recognise the code. That's why it's so difficult to beat.

Modern cars have this system as standard. This makes it very difficult to wire the car hot or use another key for starter. The system works by analyzing the chip inside the key fob or key, and sending a passcode back to the ECU (electronic control unit). The ECU recognizes that it is the correct key and that there hasn't be compromised code. The system will not allow the car to start in the event that it does not receive the correct code. Some models even inform the owner when they attempt to use an unapproved fob or key.

However it isn't completely secure. Some thieves have managed to bypass the immobiliser by using techniques such as 'hot-wiring.' This involves using the wrong wiring in a vehicle in order to trick the ECU. However, this method is quite risky and requires a lot of experience to do it without electrocuting yourself. Additionally, many modern car thieves have switched over to more advanced methods, such as using specialized apps or Bluetooth to steal the car's data and then remotely control it using their phone.

Car owners will frequently see warning lights that indicate an immobiliser gone haywire. This can happen for various reasons, but one of the most frequent is a dead or defective battery on the key fob. This problem can be fixed by replacing the battery.

If this does not work, it could be that the transponder chip is defective or the ECU is mismatched. This is more complicated to determine and fix and may require a specialist car locksmith or dealership. However, a car immobiliser may also be damaged due to water ingress or even physically being pulled away from the fob or key. If any of these problems occur it's recommended to visit an auto garage or a local dealer to seek assistance.
