Immobilizer: 2023 Chevrolet Blazer Mirror Features Owners Manual
With the 2023 Chevrolet Blazer, welcome to the convenience and security of the automotive future. This Owner’s Manual for Mirror Features delves into the Immobilizer, one of the cutting-edge safety features. An essential component of your car’s security is the immobilizer, which makes sure that only authorized users with the right key or key fob can start the engine. This guide offers thorough explanations of the Immobilizer system built into the rearview mirror as part of 2023 Chevrolet’s Blazer dedication to your safety, improving your ownership experience and bringing you peace of mind.
Immobilizer Operation
This vehicle has a passive theft-deterrent system. The system does not have to be manually armed or disarmed. The vehicle is automatically immobilized when the remote key leaves the vehicle. The immobilization system is disarmed when the ignition is turned on or in ACC/ ACCESSORY and a valid remote key is in the vehicle.
The security light, in the instrument cluster, comes on if there is a problem with arming or disarming the theft-deterrent system.
The system has one or more remote keys matched to an immobilizer control unit in the vehicle. Only a correctly matched remote key will start the vehicle. If the remote key is ever damaged, you may not be able to start the vehicle. When trying to start the vehicle, the security light may come on briefly when the ignition is turned on.
If the engine does not start and the security light stays on, there is a problem with the system. Turn the ignition off and try again. If the ignition will not change from off to on or ACC/ACCESSORY, and the remote key appears to be undamaged, try another remote key. Or, you may try placing the remote key in the cupholder in the centre console. See Remote Key Operation 0 7.
If the vehicle will not start with the other remote key, or with the remote key in the cupholder, the vehicle needs service. If the vehicle does start, the first remote key may be faulty. See your dealer who can service the theft-deterrent system and have a new remote key programmed to the vehicle. learn new or replacement remote keys. Up to eight remote keys can be programmed into the vehicle. To program additional remote keys, see “Programming remote keys to the Vehicle” under Remote Key Operation 0 7. Do not leave the remote key or device that disarms or deactivates the theft-deterrent system in the vehicle.
