Cadillac CT4 Trunk does not lock or open Inspection at your home or office.

Common reasons for this to happen:

• Broken latch: The latch is what allows your trunk to close. The latch in your trunk operates the same as the latch in your door or seatbelt. There is a connecting unit on the trunk and on the frame of the car, and when you close the trunk the two pieces latch together, sealing the trunk securely. When you open the trunk, the latch releases and allows the door to unhinge. If this latch is damaged while the trunk is closed, it can lose its ability to release. This will often happen if the car absorbs impact around the trunk. When your latch breaks, you’ll be unable to open the trunk.

• Damaged trunk cable: Some vehicles don’t have a handle on their trunk, and rely entirely on a lever in the cabin (or a button on the keys) to open. In this case, you release the latch not by pulling on a handle on the trunk, but by tugging on a trigger (usually near the driver’s seat), which accesses the trunk latch via a cable. When this cable is broken, there is no connection between the trunk latch and the trunk opening lever, and you won’t be able to open the trunk.

• Lock actuator malfunction: The lock actuator is what controls the lock on your trunk. It is a small motor with gears that shift when you lock the trunk, so that the latch cannot release the door. If this motor dies, the trunk latch will no longer be able to lock or unlock.

• Broken locking mechanism: When you press the trunk lock button inside your vehicle or on your car keys, it sends a signal to the actuator to lock the doors and the trunk. If this button doesn’t lock any of the doors, then most likely the battery in the button is dead or the button is faulty. If the button locks the doors, but doesn’t lock the trunk, then the actuator is probably at fault.
