You specifically mention your car. Why don't you just lock it up in you car. Use a good lock-box, bolted down under the seat. It works even better if you're driving your car to the other site.
If he's driving to a secure site they will or can search the car, and probably have a prohibition on weapons on site. Army base etc.
I have the same issue as kalash. Can't store anything in the car cause I go onto secure sites.
