Sorry. Was too fast with the video reply.
If the trunk closes (latch closes) but does not lock, then the lock motor is no good.
Remove the trim from the lid and look for a square plastic box with a rod attached to it. That is the "lock" motor.
Check the motor for power and ground with a test light. If power and ground ok but the motor does not do anything, replace the motor.
You can see a similar motor in the above video.
