Vehicle perimeter intrusion protection and anti-theft monitoring on the 2023 Cadillac CT5 are regulated by factory immobilizer modules, key fob radio-frequency transmitters, and door-lock status sensors.
How to Fix It:
-
Close All Doors and Hood: Ensure all windows, doors, the trunk, and the hood are completely shut to allow the security system to arm properly.
-
Press Key Fob Lock: Press the lock button on your key fob once or touch the passive entry sensor on the door handle to lock all doors.
-
Verify Security Light: Watch for the red security indicator light on the instrument panel to flash, confirming that the alarm system is fully armed.
