A consumer product dispensing system and method may include a product dispensing unit having a plurality of vending compartments. Each compartment may be adapted to contain a consumer product and may be accessible through a separate door secured with a lock. A single use access mechanism attached to each door may allow a customer to unlock the lock for a one-time access to one of the vending compartments. Once the lock is unlocked, subsequent unlocking of the lock may be prohibited until the lock is reset. The single use access mechanism may include a key capture lock system and a single use access mechanism actuating element such as a key. Such a system and method may be useful for dispensing consumer products at a location remote from the point of sale.
