: Trunk won't lock after closing

Whenever I go to slam (not hard) my trunk to close it, it makes a locking noise.

However it never locks. Is it suppose to lock or make the noise?
(It does lock when I hit the lock button on the drivers and passenger door)

I was just wondering if it is suppose to lock. For example lets say everything is locked and I want to only open the trunk with the key, when I go ahead and close the trunk it only makes a locking noise and never really locks, I then have to unlock either the driver or passenger door to lock the trunk.

Is this normal?

I have an 05 and when I close the rear gate it makes a lock noise as well but doesn't lock unless I lock my doors then it does lock this is a normal noise nothing to worry about I belive it is an electronic security latch when the doors lock it locks as long as all doors are unlocked it will be unlocked

It acts as a fifth door, so when you lock all the doors it also locks.
