Remember, that the law is different with regards to Transport and Storage.
Assuming you have a LTC-A, the only items that need to be locked in either a container or a trunk are large capacity rifles or shotguns. This is the law. Its not debatable. You may wish to debate the advisability of this. But that is another thing. Also note that trigger locks DO YOU NO GOOD with respect to transport.
When you park the car, you are now dealing with Storage laws. So that Remington 1100 that was legal to transport in a soft case in the back seat of your truck without any locking devices, now needs to be locked when you leave the vehicle with either a locking container or a trigger lock.
