Welcome to the forum. In one of the first four threads is the
Washington OC FAQ's its well worth reading through before posting questions.
Please read up on all the sections in RCW 9.41.

#1) - RCW 9.41.050 will fill you in on having a weapon in your vehicle. In both cases of loaded and unloaded, the pistol is to be locked within the vehicle and concealed from view from outside the vehicle. You might think about a small gun safe for the vehicle vs. the glove box or console.
#2) - There is no law against you locking it in your vehicle. If that was the case then I wouldn't be able to enter school property at all.
#3) - I can't speak for all detention centers but the few I have visited had lock boxes. With my gun safe in the truck I found it easier to lock up and head in.
