i lost my car key. need to get my registration out of the car becuase i need it to order a new key. if AAA opens the car so i can get my registration, will they be able to lock it again?

If you can get it opened, you can use the inside key lock and close the doors after locking the car. Make sure you have all the necessary paperwork and information necessary for new keys to be made so you don't have to call AAA out again.

A A A was able to open the car and lock it again but the security system does not allow you to get into the glove compartment or trunk.

Your next stop would be either getting something to pop the lock on the glove compartment or call a locksmith. (locksmith's are no doubt cheaper.) Will the place you bought the car if it is a dealer accept your sales receipt, insurance card, or anything else you have to prove ownership? How about past motor vehicle renewal notices? Try AAA motor department bureau to get a copy of your registration? There must be a way to convince the dealership you won the vehicle.
