With a valid permit is it legal to have your gun locked (secured in a locked box) in your car while on school property.
This cannot be answered with a simple yes or no. There are different issues here that need to be addressed.
First, a permit is not required for Nevadans to have firearms in our vehicles in Nevada, Nevada allows it's citizens to be armed in our vehicles and in our homes. As well, the firearm is not required to be locked up in a compartment in our cars. It can be out in the open such as on the dash or in a rifle rack. The firearm is not allowed to be cc on our person while we are in our cars unless we have a valid cc permit. This is what I was taught. I hope it's correct because that is how I do it.
Second, as for having a firearm in your vehicle on school property, here is what the Nevada Revised Statute says:
NRS 202.265 Possession of dangerous weapon on property or in vehicle of school or child care facility; penalty; exceptions.

(c) A nunchaku or trefoil;
(d) A blackjack or billy club or metal knuckles;
(e) A pistol, revolver or other firearm; or
