* Trunk release button inside the car: This is the most common method. Look for a button, usually located on the driver's side armrest, center console, or near the steering wheel. It might be labeled "Trunk," "Boot," or have a trunk icon.
* Key fob: Most modern Cadillacs have a key fob with a button specifically for unlocking the trunk. Press this button to remotely unlock the trunk.
* Key in the lock: Older Cadillacs may have a keyhole in the trunk lid itself. Insert your key and turn it to unlock.
* Emergency trunk release: In case of emergency, most Cadillacs have an interior emergency trunk release, usually located in the trunk itself or under the rear seat. This is meant to be used if you're trapped inside the car and need to escape via the trunk. The location varies by model year.
To know the *exact* location of the trunk release for *your* Cadillac, consult your owner's manual. The manual will show diagrams and specific instructions for your vehicle.
