2023 Cadillac LYRIQ Vehicle Security
Vehicle Security
This vehicle has theft-deterrent features; however, they do not make the vehicle impossible to steal.
Vehicle Alarm System
Arming the Alarm System
- Turn off the vehicle.
- Lock the vehicle in one of three ways:
. Use the remote key.
. Use the Keyless Access system.
. With a door open, press
on the interior of the door. - After 30 seconds the alarm system will arm, and the indicator light will begin to slowly flash. Pressing on the remote key a second time will bypass the 30- second delay and immediately arm the alarm system. The vehicle alarm system will not arm if the doors are locked with the mechanical key. If the driver door is opened without first unlocking with the remote key, the horn will chirp and the lights will flash to indicate pre-alarm. If the vehicle is not started, or the door is not unlocked by pressing
on the remote key during the 10-second pre-alarm, the alarm will be activated. The alarm will also be activated if a passenger door, the tailgate, or the hood is opened without first disarming the system. When the alarm is activated, the turn signals flash and the horn sounds forabout 30 seconds. The alarm system will then re-arm to monitor for the next unauthorized event.
Disarming the Alarm System
To disarm the alarm system or turn off the alarm if it has been activated:
- Press on the remote key.
- Unlock the vehicle using the Keyless Access system.
- Start the vehicle.
To avoid setting off the alarm by accident: - Lock the vehicle after all occupants have exited.
- Always unlock a door with the remote key, or use the Keyless Access system. Unlocking the driver door with the mechanical key will not disarm the system or turn off the alarm.
How to Detect a Tamper Condition
If is pressed on the remote key and the horn chirps three times, an alarm occurred previously while the alarm system was armed. If the alarm has been activated, a message will appear on the Driver Information Center (DIC).
Immobilizer
See Radio Frequency Statement395.
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 vehicle is turned off. The immobilization system is disarmed when the vehicle is turned on and a valid remote key is present 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 your vehicle. When trying to start the vehicle, the security light may come on briefly. If the vehicle does not start and the security light stays on, there is a problem with the system. Turn the vehicle off Nand try again. If the vehicle will not turn on or off, and the remote key appears to be undamaged, try another remote key. Or, you may try placing the remote key in the backup location. See Remote Key Operation8. If the vehicle will not turn on or off with the other remote key or in the backup location, the vehicle needs service. If the vehicle does turn on or off, the first remote key may be faulty. See your dealer. It is possible for the immobilizer system to learn new or replacement remote keys. Up to eight remote keys can be programmed for the vehicle. To program additional remote keys, see “Programming Remote Keys to the Vehicle” under Remote Key Operation8. Do not leave the remote key or device that disarms or deactivates the theft-deterrent system in the vehicle.
