A secure storage system may provide secure, portable, and rapidly accessible storage for articles such as firearms. Such a system may have a shell with first and second shell members that can be closed to keep the articles secure, or opened to provide accessibility. A locking mechanism may be used to lock the shell in the closed configuration. The locking mechanism may be controlled by a wireless receiver that receives a signal to unlock the shell. The shell may include a secure-side programming interface to allow a user to set control system parameters when the system is in the unlocked state.
