Remote door locking security and keyless entry transmission on the 2023 Cadillac CT5 are managed by radio frequency key fobs, body control module receivers, and electronic door latch actuators.
How to Fix It:
-
Press the Lock Button: Aim your key fob toward the vehicle and press the lock button once to secure all doors and trunk automatically.
-
Verify Light Flash: Watch for the exterior hazard lights to flash or listen for a brief horn chirp confirming that all doors are fully locked.
-
Test Door Handles: Pull a door handle after walking away to ensure the security system is engaged and doors remain latched.
