Thanks for making that clear. I was thinking vehicle trasport but a locked trunk can mean more than one thing. And a locked case need not be in the vehicle's trunk - as in a console safe, or a small lock-box under the seat.
I'm presuming these transport laws were enacted, in part, to address someone without a carry license having immediate access to a loaded firearm in a vehicle, again in part, for officer safety, or to address stop-and-shoot hunting.
But attempting to ascribe some logic to them might be stretching things...
The
Illinois Supreme Court case that was recently decided is a fascinating study on the matter. The lower court said storing a gun in a locked console wasn't storing it in a locked case, saying a case, by definition, is portable. The ISC trashed that arguement. Sadly, it's gone back to the lower court as at issue is whether the gun was in an opened console safe with the keys dangling from the lock, as the police say, or whether the console safe was locked and the keys were in the glove box, as the driver and passenger say. The problem was, the driver's wallet was in the console safe and he claimed he told the police that he had to enter his console safe where his gun was locked to produce a license on a stop.
Bottom line - if the cops lie, you're screwed. Also, don't keep your driver's license/registration and gun together in the same place.
The practical application of interest to me is in keeping a long-gun in the back of the car. If I had one I could bring to MA (except for a Mosin Nagant and Ruger 10/22, they all have evil features), a push-button safe with mag aside unloaded rifle seems legal.
