 What is the Immobilizer/Anti-Theft System on an INFINITI?

The immobilizer or anti-theft system on an INFINITI is a sophisticated technology designed to prevent unauthorized operation of your vehicle. It verifies that the key to start the engine is correct. If the key is incorrect, this system blocks different actions to prevent the car from starting.

 A warning light will turn on when the immobilizer system is activated on your INFINITI. If the car does not recognize the key signal, two things may happen: The engine may turn on for a few seconds and then stop, or the engine will not turn on. Depending on the electronic immobilizer system, the car’s computer will disable the fuel pump, the ignition coil, and the injectors.

 Why is the Immobilizer Activated on an INFINITI?

 The main reason is that the car’s computer does not recognize or detect the signal from the chip inside the key. The most common reasons as to why this happens are:

  •  A low battery of the key or the remote control: the chip will not send the signal.

  •  The key’s chip is damaged or has been decoded: it may happen if the key is damaged or gets wet.

  •  Faulty electrical wiring may happen in the antenna, immobilizer unit, or the engine’s computer.

How to Reset the Vehicle Immobilizer/Anti-Theft System on Your INFINITI

 Resetting the immobilizer system on your INFINITI is a straightforward process that you can do yourself.

 Here are the steps:

  •  Leave the ignition switch in the ON position for approximately 5 seconds.

  •  Place the ignition switch in the OFF or LOCK position and wait approximately 10 seconds.

  •  Repeat steps 1 and 2.

  •  Restart the engine while holding the device (which may have caused the interference) separate from the registered INFINITI Vehicle Immobilizer System key.

    These steps may vary slightly depending on your INFINITI vehicle’s specific model. Always refer to your vehicle’s owner’s manual for the most accurate information.
